Best Air Purifiers for Cat Hair

Before I review the best air purifiers for cat hair, I want to let you know how I decided on these products. What features were important? Why were these important to me? Below are all the features I was looking for in the perfect product and what I based my search around.

• Maximum Power: Air purifiers come in many different strengths, and the power you need will depend on the severity of your allergies and the size of the room you’re using the gadget in. For me, I wanted to find a powerful air cleaner for cat hair.
• Low Noise: You will find that some air purifiers will be noisy, which can be frustrating! Therefore, I looked for a product that was virtually inaudible as to not cause any disruption to me or my pet.
• HEPA Filter: Top of the range air purifiers will have a HEPA filter to catch tiny particles as small as 0.3 microns, though you can get more porous filters that will trap larger particles such as cat hair. As I wanted an air purifier for cat allergies and cat hair, HEPA filters are preferable.
• Carbon Filter: For controlling pet odors, the air purifier must have an activated carbon filter that can catch and absorb nasty smells such as odors from cat urine, feces, dander, and hair.
• Timer Settings: Some air purifiers have timer settings so that they only come on at specific times of the day, which is great for prolonging the life of the filter and saving energy.

Of course, the strength and filter type you need is down to what issue you’re trying to solve. Similarly, whereas having a timer setting and low noise is preferable to me, these may be issues that you’re not too worried about. However, these are the factors I based my search for the perfect air purifier for cat hair on.

1. LEVOIT Air Purifier for Pets & Allergies (Best All-Rounder)

Hands down, the best HEPA air purifier for cat allergies is the LEVOIT Air Purifier. Since using this, my allergies have disappeared! Not only that, but my house is free from cat hair and smells so fresh, will all nasty odors having been eliminated. Plus, for the price, you cannot beat it.

Why is this air purifier so effective? It has a triple filtration system in place that is made up of a pre-filter, a True HEPA filter, and finally a high-efficiency carbon filter. All large dust particles and cat hair are caught in the pre-filter, pet dander and other allergy-causing particles are caught in the HEPA filter, and all odors are absorbed by the carbon filter. In fact, together this powerful trio removes 99.97% of airborne contaminants.

Alongside its impressive filtration, this air purifier is also powerful. The motor rapidly circulates air, allowing for all the air in a small-sized to medium-sized room of up to 129 square feet to be filtered up to four times per hour. Even rooms of up to 516 square feet in size will be cleaned once per hour, and you can choose between three different settings to select a fan speed that suits you.

Another perk is the noise of this air purifier, or should I say, the lack of noise! This product is whisper-quiet and when on the lowest setting makes noise as quiet as 25dB. I leave this on when I go to sleep and am not disturbed by it running whatsoever.

Unfortunately, this air purifier for cat hair doesn’t have a timer and must be switched on and off manually. However, the filter is expected to last for 6-8 months, even when constantly in use. When the filter does need replacing, a built-in replacement indicator will flash so you’ll never have to sacrifice air quality.

Pros

Cons

2. Gocheer Air Purifier for Pet Dander Allergens (App Controlled & Great for Large Rooms)

If you have a larger space that you need to purify, try the Gocheer Air Purifier for Pet Dander Allergens. This product easily cleans up to 1,102 square feet in just 15 minutes!

As this is such a powerful air purifier, it does also work well in medium-sized spaces such as master bedrooms or living rooms, as you can have it running on the lowest setting while not compromising its efficiency. This is great at it prolongs the life of the filter and keeps noise to a minimum. That being said, this air purifier is pretty quiet as it is even on the loudest settings!

Just as with my top pick, this air cleaner for cat hair also uses a combination of a True HEPA filter and an activated carbon filter to capture all airborne particles that are 0.3 microns in diameter or larger. This includes cat hairs, dander, and nasty litter box and pet odors. Of all the particulates and allergens of this size, this air purifier captures 99.97% of them.

This air purifier has four different fan speeds to choose from, as well as an auto mode setting which continually monitors the air and adjusts its speed accordingly. I also love the timer setting which can be set to turn the gadget off automatically after 1, 2, 4, or 8 hours, which is great for conserving energy and prolonging filter life, and means you can adapt how you use the air purifier based on your individual needs.

What’s really great about this gadget though is how it’s controlled. It has an advanced touch screen panel where you can easily control everything from fan speed to timer settings, and from sleep mode to lighting. There is also a child lock feature to prevent your little ones from messing with the settings. Additionally, you can also change all these settings through a smartphone application when connected to Wi-Fi for added convenience.

The main downside of this air purifier is its size. It is free-standing, measuring 14.7 inches long by 15.9 inches wide, and has a height of 31.9 inches. However, if you have space for it in your home it is an incredible product.

Pros

3. Hamilton Beach TrueAir Air Purifier (Best Budget Option for Cat Hair)

Another wonderful product is the Hamilton Beach TrueAir Air Purifier. If you’re on a budget but still wish to rid your home of cat hair, this could be the solution you’ve been dreaming of!

This high-performance system has a triple filtration process, again combining a pre-filter specifically to catch pet hair and large particles, an activated carbon filter to trap and absorb odors, and a True HEPA filter to capture dander and other allergens.

What is fantastic about this product is that the pre-filter and HEPA-grade filter are both permanent and you can vacuum them to keep them clean. This can substantially cut costs for cat owners who could end up spending a fortune on filter replacements. The carbon filters will need replacing, but the costs will still be kept lower than if a total filter replacement was required.

This air purifier also runs quietly while working powerfully, with three different fan speeds which can cover an area of up to 140 square feet. This is not as large coverage as other air purifiers but is ideal for a small bedroom, office, or nursery.

Pros

Cons

4. Hathaspace Smart True HEPA Air Purifier (5-in-1 Purification System)

If you really want to understand what’s in the air you’re breathing, try the Hathaspace Smart True HEPA Air Purifier.

This air purifier has a 5-in-1 purification system. The cold catalyst filter catches cat hair and other large particles, the activated carbon filter absorbs pet odors, the antibacterial filter targets bacteria and germs, the True HEPA filter removes all allergens as small as 0.3 microns, and lastly, the ionizer releases negatively charged ions to further eliminate odors. With this five-layer protection, your home will be hair- and allergy-free.

Unfortunately, ionizers also release ozone into the room, making them not ideal for everyone. However, this air purifier only releases a tiny amount that is safe for your health, and there is the option to turn the ionizer off if you’re feeling wary of it.

This product also has several smart features, such as the air quality sensor which detects and displays the quality of the air in your home. This will conveniently be displayed on the screen so you can learn more about the quality of the air you’re breathing.

There is also an auto mode, and when the air purifier is in this setting, it will adjust the fan speed automatically based on the real-time air environment picked up by the air quality sensor. Alternatively, operate the gadget yourself by using the convenient remote control, meaning you won’t even need to get up from the couch or your bed!

This air purifier for cat hair is also powerful, cleaning the air in a 350 square foot room twice per hour. Despite the strong power, you’ll also find this product is quiet when on its lowest settings, and even has a sleep mode so that you can have a peaceful slumber without being disturbed. However, when on full blast it can be a little noisy.

Pros

Cons

5. Blueair 221+ Air Purifier (Best for Eco-Conscious Pet Owners)

If you have a large room that you wish to clear of cat hairs, try the Blueair 221+ Air Purifier. Not only does this air purifier do a good job at trapping airborne particulates, but it also has a low energy consumption of 30 to 60 watts, great for those concerned about the environment and wishing to contribute to a healthier planet.

The simplicity of this design is what makes it so fantastic. Whereas some of you may love fancy touchscreen displays and a breakdown of the quality of the air you’re breathing, others prefer a minimalistic design. The Blueair Air Purifier has one button which is used to adjust the settings, which also glows red when the filter needs replacing.

Once again, a three-stage filtration process ensures all cat hairs, allergens, dander, and pet odors are trapped and eliminated from the air. The pre-filter catches large particles and is washable to keep costs down, extend the lifespan of the gadget, and please the eco-conscious owner. Catching odors is the activated carbon filter, and smaller allergens and pollutants are captured in the HEPA filter.

Unfortunately, this is not a True HEPA filter as it falls just slightly short of the specs. That being said, it only narrowly misses the mark and still removes 99.97% of particulates from the air.

The other downside of this air purifier for cat dander is that it is freestanding and takes up valuable floor space. However, it does have 360-degree air intake for optimal performance no matter where you place it in your room. It is also designed best for large spaces where floor space will likely not be an issue, cleaning a 540 square feet room five times per hour.

Pros

Cons

6. Alen FLEX Air Purifier for Large Rooms (Removes 99.99% of Airborne Particulates)

Another sleek and modern air purifier for cat allergies that I love is the Alen FLEX Air Purifier for Large Rooms. Coming in eight different colors, this product will complement any décor in any home.

When it comes to filtration, this gadget has a medical-grade H13 True HEPA filter, removing 99.99% of bacteria and other airborne particulates such as cat dander, pet hair, and odors. It can trap airborne particles that are as small as 0.1 microns, providing top quality purification.

You can also set the fan to four different speeds depending on your needs. Plus, on the turbo setting the air purifier emits pink noise frequency, a lower tone than white noise. This is proven to help you sleep, and so ideal for anyone worried that the sound of their air purifier will keep them up at night. Combined with purified air to help improve sleep, you’re guaranteed a peaceful slumber.

If you have a large room, this air purifier for cat hair also cleans rooms of up to 700 square feet twice per hour. This makes it great for bedrooms, family rooms, and kitchens.

There is also a timer function on this machine, meaning you can set it to run for 2, 4, or 12 hours. This will help to conserve energy and prolong the filter life as it won’t accidentally be left running. Also, if you have kids, a handy lock button means they won’t be able to accidentally adjust the settings.

Pros

Cons

7. Pure Enrichment PureZone Halo Air Purifier (Fab for Smaller Spaces)

Another fantastic product, especially if you are short on space, is the Pure Enrichment PureZone Halo Air Purifier. Measuring only 12” by 12”, this air purifier can conveniently fit anywhere around your home, making it the perfect size for rooms up to 100 square feet.

It too has a True HEPA filter combined with an activated carbon filter which together acts as an extremely effective air purification system, removing 99.97% of cat hair, dander, and pet odors. Due to this passive purification, you can also rest assured that you will be safe from respiratory illnesses as it is 100% ozone free.

This air purifier does lack a pre-filter, which is not essential in removing contaminants. However, it does capture large particles such as cat hair so that the other filters have a prolonged lifespan, making this a minor downfall.

For anyone not too tech-savvy, this air purifier for cat hair is also extremely easy to control with four simple buttons. Using these, you can select between three automatic timer settings, or run continually after choosing one of three fan speeds. Optional lighting can also be controlled here, with the choice of a bright light, a blue mood light, or sleep mode.

According to reviews, the lowest two settings are ultra-quiet, whereas the third is slightly noisier. That being said, this does completely depend on your tolerance to sound and it is still a fantastic product.

Pros

Cons

8. RabbitAir MinusA2 Ultra Quiet HEPA Air Purifier (Customizable Panel & Filter)

Anyone wanting to tailor their air purifier to their exact needs and home décor, the RabbitAir MinusA2 Ultra Quiet HEPA Air Purifier could be for you.

This air purifier for cat allergies and pet hair has an incredible 6-stage filtration process, including a permanent and washable pre-filter for pet hair, a medium filter for dander, a HEPA filter for allergens, a charcoal-based activated carbon filter for odors, a negative ion generator for general freshness, and a customized filter of your choice. Depending on your air quality to start, all filters will last up to 2 years when used for 12 hours daily!

For the customized filter, you have the choice from Germ Defence, Pet Allergy, Odor Remover, or Toxin Absorber, allowing you to decide which factor you wish to cleanse further from your air. This level of personal control extends beyond the inside of the unit, and you can also choose a series of designs for the front panel so that the air purifier works well in your home.

I also love that this air purifier can be freestanding or mounted on the wall. This is great if you don’t have the floor space for a larger model, but do have a big room to clean. The RabbitAir MinusA2 purifier can clean a 700 square foot room up to twice per hour while taking up no space on your floor.

For any cat owner concerned about noise, this air purifier is also known to be whisper-quiet. The cutting edge motor runs at an impressive six different speeds, with noise levels ranging from only 20.8 dBA to 45.6 dBA. This is as quiet as rustling leaves and only gets as loud as a babbling brook.

Pros

Cons

9. Germ Guardian Pluggable Small Air Purifier (Best Portable Design)

The sleek Germ Guardian purifier has got your back wherever you go. I’ve been traveling with it for a while now, and all I can say is that it’s one of the best small portable purifiers I’ve ever tried. Since I can’t imagine going away without my cats, I often bring them with me on trips, so the purifier tags along our journey.

The device weighs only two ounces, meaning that you can also easily move it around your home and take it from one room to another with ease. Then, you simply need to mount it on the wall and purify the area around the litter boxes for your felines, or anywhere else in your home!

If you’re severely allergic and want to get a purifier that will cover your bedroom, this might not be the device for you. It doesn’t have a large range since this is a small device that’s not as powerful as others I reviewed on this list. But it’s ideal for small spaces and travel, as already mentioned.

In addition, you won’t have to replace a filter – this unit uses a UV-C bulb instead which needs replacing 10 to 12 months. It will effectively reduce unpleasant pet smells and kill airborne viruses and germs. Yet, unfortunately, the lack of a true filter means it doesn’t get rid of allergens.

Pros

Cons

10. Pure Enrichment PureZone Portable Air Purifier (Best for Traveling)

Do you travel around a lot and always take your pets with you? Or perhaps you are visiting friends and family that have cats and are looking for a solution to help ease your cat allergies? Well, here is your answer – the Pure Enrichment PureZone Portable Air Purifier.

As the name suggests, this gadget is fully portable and perfect for anyone who needs to pack up their air purifier and take it with them. The unit only measures 8.5 x 3.3 x 2.7 inches and weighs 0.6lbs. Plus, there is an adjustable handle at the top so you can conveniently carry it with you wherever you go!

The air purifier also runs on a rechargeable lithium battery so you won’t need to be near a power supply to use the unit. Simply charge it up before you go using the USB charger provided and it will run for up to 12 hours straight. You can then plug it in at your final destination for continued fresh air while away from home.

This air purifier may be small, but it is still powerful. It uses advanced two-stage purification with both a True HEPA filter and an activated carbon filter. The former removes 99.97% of all cat hair, dander, and other allergens, while the carbon filter traps all nasty odors and smoke.

You have the choice of three different fan speeds while the air purifier is running. The lowest is incredibly quiet and barely noticeable so great while sleeping. This also means you can take it on public transport or flights without feeling like you’re disturbing other passengers.

Pros

Cons

11. BISSELL air320 Smart Air Purifier with HEPA (Every Purchase Saves Pets)

The BISSEL air320 Smart Air Purifier with HEPA is a very fancy piece of kit tailored towards those of you with large homes. Specifically, it’s recommended for rooms of 327 square feet or greater. It filters all the air in this room 4.8 times every hour and even comes with AHAM certification to prove it.

It relies on triple filtration to achieve this. The fabric pre-filter helps to catch all larger particles in the air to avoid them clogging up the other filters. Then, a medical-grade HEPA filter captures 99.97% of particles 0.3 microns and smaller. This includes all allergens and irritants such as pet dander. Finally, the carbon filter traps and removes odors.

One of the things I love most about this gadget is its automated CirQulate System. Within the air purifier, there are particle sensor monitors that continually test the air in your home. The fan speed will then adjust automatically to guarantee you have continuously clean air.

The usability and maintenance of this unit are also incredible. There is a simple dial and button on top of the unit which you use to adjust the fan speed and power. Additionally, the filters can easily be accessed from the front when they need to be cleaned or replaced.

The one thing this air purifier is missing is timer settings; you cannot schedule the machine to turn on and off at specific times of the day. However, it is ozone-free, has five different fan settings, and its auto mode means it can keep tabs on the air in your home while you’re busy.

Finally, BISSELL is a proud supporter of The Pet Foundation, a charity focused on helping homeless pets. Whenever you purchase one of their products, the company donates a portion of its profits to this charity. So, you’re helping to save pets with every purchase!

Pros

Cons

12. Hathaspace Air Purifier with True HEPA Filter (Medical Grade Air Filtration)

We already have one air purifier from the Hathaspace brand on this list, and their impressive collection of products keeps on giving. This Hathaspace Air Purifier with True HEPA Filter is one up and takes cleaning the air in your home to the next level.

The unit guarantees medical-grade air filtration using an H13 True HEPA filter. This is more advanced than the H11 True HEPA filter most air purifiers have – it captures 99.95% of particles between 0.3 microns and 0.1 microns in addition to the usual 99.97% of larger particles.

Like the brand’s other air purifier that I have already reviewed, this gadget too relies on advanced five-stage filtration. It also has a handy sleep mode that won’t disturb you at night, and an auto mode that works to continuously monitor the air in your home and adjust its power accordingly.

However, this unit can cover an area double the size, cleaning all the air in an area of up to 1,500 square feet per hour. It also has four different fan speeds for more fine-tuned control. Plus, I prefer the all-white look of this unit which blends well into any home interior.

One of the biggest perks has to be the feedback it provides users. There is real-time air quality index feedback so you can precisely see the quality of the air in your home every second. I also love the handy filter change indicator. You’ll never forget to change an old filter again so the air in your home is never compromised.

Pros

Cons

13. Lasko Pure Platinum HEPA Air Purifier (Most User-Friendly)

The Lasko Platinum purifier is a premium option worth every single dollar. If you ever decide to get a user-friendly device with all the smart features, sensors, buttons, and electronic controls, this one is it. I’ve always been into gadgets that make my life easier, so I had to try the Lasko purifier.

I’m obsessed with how powerful this air purifier is, and it can easily cover spaces up to 200 square feet. In addition, it removes dust, dirt, pet hair, odors, allergens, and smoke. The air in your home will be completely free of any nasty pet smells and your cat allergies will disappear!

To achieve such powerful filtration, the device is equipped with an advanced three-stage filtration system. It also has an additional UV light for killing bacteria, viruses, and mold spores. There is also a handy filter reminder that lets you know when the filters need replacing.

I also enjoy all the smart features which make the gadget extremely easy to use. These include a timer, a child lock mode, and a sleep mode. You can control the air purifier and all these settings using the remote control. And, if the purifier senses allergens in the air, it starts working automatically without you having to turn it on!

Although this is a fantastic purchase, there is one thing that I have to mention. The brand offers you a one-year filter supply, but you’ll have to purchase the filters yourself once that year is done. They’re on the costly side, just like the device, but thankfully they last a very long time.

Best Air Purifier for Cat Owners Buying Guide

While I think these are all fantastic products and have included options for all size rooms, severities of allergies, and budgets, I understand that they may not be for everyone. In fact, there are a huge number of different air purifiers on the market, meaning you may wish to shop around.

Here is what you should look for in an air purifier for cat hair.

Cost

Air purifiers are not a cheap piece of kit. Plus, there is the cost of replacement filters every 3 to 6 months that also needs to be considered.

It is not always true that the most expensive air purifiers are the best. You can purchase an efficient machine that removes almost all airborne particulates including cat hair, pet dander, and pet odors for cheap. Nevertheless, more expensive gadgets will often come will extra bells and whistles, such as touchscreen displays, additional heating or cooling features, or stronger filters.

I advise you to set your budget first and then take a look at all the products within your price range, as this is a great way to quickly whittle down the huge range of air purifiers on the market.

Filter Type

The success of an air purifier obviously depends on its filter. A machine with a poor filter will struggle to capture and remove anything from the air!

Often, air purifiers will have three different filters; a pre-filter, an activated carbon filter, and a HEPA or HEPA-style filter. The best air purifiers will have all three and include a True HEPA filter to capture 99.97% of airborne particulates.

That being said, the filtration system you need largely depends on your reason for getting an air purifier. If you simply want an air purifier for cat hair, yet are not bothered about removing allergens or odors, a more porous filter will suffice. If you additionally want an air purifier for cat litter odor or other pet smells, having an activated carbon filter is a must. And if you have severe allergies because of your pet, a True HEPA filter will ensure all allergens are captured successfully.

In my opinion, opting for a triple filtration system is best as then you eliminate all cat hair, dander, allergens, and odors. If you can hit four birds with one stone, then why not?

When choosing a product, the availability of the filter is also essential. Unfortunately, some big companies discontinue their filters which can be extremely frustrating if you have just bought their air purifier. Always check with the supplier as to how long replacement filters will be available or else you may become unstuck.

Filter Replacements

In general, most filters last for months, but you’ll need to replace them once or twice a year. When choosing a product, the availability of the filter is essential. Unfortunately, some big companies discontinue their filters which can be extremely frustrating if you have just bought their air purifier. Always check with the supplier as to how long replacement filters will be available or else you may become unstuck.

Filter cost is another consideration. We all dream of getting the most expensive purifier, equipped with top-notch features that will make your life so much easier. However, a costlier device might mean more expensive filter replacements. When you put together a list of potential purifiers you want to buy, dig around to find out how often you need to change the filters and how much they cost. If you’re not ready for a costly investment, you should opt for a device with cheaper filters. 

Size of the Room

How large of an area are you trying to clean the air of? You will find all air purifiers run at different powers, and the strength you need will depend on the size of the room. Some air purifiers will clean the air in rooms of up to 150 square feet a couple of times per hour, whereas stronger products can clean upwards of 1,000 square feet several times per hour.

The best way to choose the right air purifier for you is to measure the size of the room and find a product that can successfully clean the air in the room accordingly. Measure the room with a tape measure and determine the square footage by multiplying the width by the length. Once you have the numbers, finding the right purifier will be much easier. 

Each manufacturer mentions the purifier’s power in the product description part, but they also include the square footage that the device can cover. So, read the description in detail, and you’ll know whether the product is suitable for your room size. 

One thing to keep in mind is that this formula doesn’t take into consideration the ceiling height. If your ceilings are quite tall, you should definitely choose a more powerful purifier, or know that the one meant for your square footage will need more time to do the job.

Number of Pets

In addition to room size, do consider the number of pets you have. This also impacts how powerful you need the air purifier for cat hair to be. The more cats you own, the more cat hair and pet dander will be circulating in the air and need to be removed. This will require more power than otherwise.

Whichever purifier you get you’ll need to change filters faster if you have more cats. Therefore, if you want to make things easier, you should find a model with an auto-cleaning feature and a filter signal that lets you know when you should replace the filters. 

You should also clean the entire purifier more frequently since more dander and cat hair will be circulating in the air. Unfortunately, even the best purifiers can be clogged if you don’t clean them. So pay more attention to the vents and wipe them at least once every week.

Noise

Noise is a huge factor when choosing an air purifier. Almost all air purifiers will come with multiple fan speeds. This is great as it provides you with additional control over the noise of the machine and means you can adjust the speed settings to your preference. However, all products make some noise when running, especially on the highest setting.

Always check the noise levels emitted by the air purifier and be careful not to fall into the trap of only looking at the noise levels for the lowest setting. Often, manufacturers will sell the product as being whisper-quiet, when in reality the gadget is only quiet when on the lowest setting. If you cannot have your air purifier on a higher setting because of noise, it will not be cleaning your air properly. Whereas noise is important, you cannot compromise the cleaning performance of the unit for it.

The noise we can tolerate is down to personal preference, so you must consider this when purchasing a product. If you will be using the air purifier for cat hair in your bedroom, this is even more essential as it could disrupt your sleep.

Timer Settings

In my opinion, it is also worth looking for an air cleaner for cat hair that has optional timer settings.

By setting a timer you can help to save energy, keep costs down, and do your bit for the planet. This is also great for prolonging the life of your filter, as the longer the filter is running without needing to be, the more the filter is getting clogged up unnecessarily.

For example, you may wish to have your air purifier on as you sleep, but don’t need it on for the entirety of the night. Timer settings will allow you to have the unit running for a few hours as you fall asleep. Fancier machines will also allow you to program specific speeds at certain times of the day or week for perfect air purification at all times.

Size & Mobility

You will also need to consider the size of the air purifier as you need to find space for it in your home. Size is also an important factor if you need to move the air purifier around your home.

Some air purifiers are small and easily portable and can be set atop a chest of drawers or a bookcase. However, many are large and freestanding, taking up floor space. Often, the larger the area you need to clean, the bigger the unit. This is because the filter and power must be bigger to clean all of the air effectively, and so the size of the whole unit will increase.

That being said, you can get sleek and innovative designs that take up little floor space, which is ideal if you have a smaller home. Also, look for air purifiers that have casters or handles so that even larger units can easily be moved around the home.

The placement of the unit is also important to ensure it works effectively, which goes hand-in-hand with size. You will need to position the unit away from doors and windows as the fresh air can affect the filtration. Also, some air purifiers take in air from 360 degrees, but those that only have an air intake from one side must not be placed in the corner of a room, nor behind furniture.

Therefore, be sure to choose an air purifier that is the right size to clean the air in the room, but also will fit comfortably into the space so that it can still work effectively.

Speed And Efficiency

Speed and efficiency are two other factors that should influence your decision. No matter which brand or budget you opt for, the device you’ll buy should be fast and efficient. In other words, you first have to learn about Clean Air Delivery Rate (CADR) and speed.

CADR is a number that signifies the volume of filtered air the purifier can deliver per minute. It’s measured using cubic feet, and the final result depends on the type of particles you are removing from the air. The CADR result will also depend on the purifying speed you’ll use. Setting the device to a higher speed will eliminate the particles faster, and if it’s set at a lower speed, it will take it longer to get rid of these pollutants. 

Many manufacturers include a device’s CADR number in the product description. However, if you want a more efficient purifier, you should look for higher numbers and multiple speeds. The smoke CADR numbers should be at least two-thirds of your room’s surface measured in square footage. Again, this is something to keep in mind when you want to ensure that you have a quality product that will work for your room size.

Speed is the factor most people don’t even think about since they’re buying a purifier and not a device such as a hair blower or oven. Nevertheless, air purifiers also have multiple speeds, and according to research, a good device should clean the room six times every hour. 

Additional Features

Many air purifiers have optional additional features that may be beneficial to you. Some of these features include extra filters, auto-clean, sleep mode, child lock mode… the list goes on! All of them are meant to elevate the experience to a new level and make your life easier. Here is a look at some of my favorite extra features you might be interested in.

• Automatic Monitoring: These air purifiers have sensors that continually monitor the quality of the air in the room by assessing the number of airborne particulates in a given area. Based on this, the device will automatically change its fan speed to provide the best cleaning power possible, while not running on a higher than needed power unnecessarily.
• Air Quality Display: Some more advanced machines will also have an air quality display, allowing you to know more about the air you’re breathing and to check that the air purifier is working.
• Night Mode: Another feature could include a night-time mode, whereby the fan runs at a lower and quieter speed and any lighting from the unit is dimmed. This is useful if you are a light sleeper and will be using the air purifier in your bedroom.
• Automatic Cleaning: Many purifiers come with an auto-clean feature that detects pollutants in the air and starts cleaning it without your command. This is an extremely useful feature for everyone since there are times when you’ll forget to turn on the purifier or you’re too busy to get to it.

Why Do I Need a Pet Air Purifier?

You may be wondering if an air purifier is necessary for your home, so here are several reasons that you’d benefit from purchasing one of these gadgets.

Reduces Your Allergies

Pet allergies are extremely common among cat owners, which can lead to unpleasant symptoms such as sneezing and coughing, runny noses, stinging eyes, and difficulty breathing. Being an allergy sufferer myself, I know how frustrating and exhausting this can be when suffering on a daily basis.

Many people assume that cat allergies are down to cat hair when the majority of allergies are caused by dander. Dander is what we call the tiny pieces of dead skin that peel off your cat as it sheds fur. As your cat gets older, their shedding will gradually get worse. It also happens more frequently in the warmer months of the year.

Air purifiers can catch dander and eliminates it from the air, alongside other allergens too such as pollen which causes hayfever or dust mites. Therefore, if you suffer from any form of allergy, having an air purifier would well be your saving grace.

Reduces Your Cat’s Allergies

In addition, these purifying devices can be beneficial for your feline. Although cats appear as strong creatures that can take care of themselves, they can be allergic to a variety of things including pollen, dust, mold, and even cat food!

You should be concerned if you ever see your cat licking its fur off. This is a strong sign that your furry buddy is also an allergy sufferer. Other symptoms include sneezing, scratching, diarrhea, and vomiting.

When the air in your home is purified from these allergens, your cat can feel better and will start healing faster. However, I can’t help but mention that you have to visit your vet if you ever notice symptoms that point to allergies and find the actual cause. Still, getting an air purifier is a great first step.

Reduces Mess

Whereas pet hair itself doesn’t cause allergies, it does cause a huge amount of mess. This is particularly true when the fur starts to form clumps on your carpet and furniture, which will otherwise need to be vacuumed away.

Air purifiers capture cat hair that is airborne in their pre-filter, preventing the fur from settling on your furniture and leaving a mess around your home. This saves you time and effort when cleaning, as well as gives you a nicer and fresher home to live in.

Reduces Odors

As a pet owner, smells such as dirty litter trays or a musty cat scent are often seen as an unavoidable by-product of having a feline friend. However, this doesn’t need to be the case!

Air purifiers can also capture odors in the air. Both True HEPA filters and activated carbon filters are effective in capturing odors. The HEPA filters catch the tiny airborne particles and contaminants that are emitting the nasty smells, and the activated carbon filter absorbs the chemicals that create the odors.

Together, these two filters can effectively remove nasty odors from your home. Whereas they are effective in eliminating pet smells, they can also remove smells from cooking or smoking, which is an added bonus.

What Are The Different Types of Air Purifiers?

There are two main types of air purifiers: active and passive. Active air purifiers are active in the sense that they emit certain particles or ions that neutralize particles in the air to eliminate them. On the other hand, passive air purifiers wait for the air contaminants to run through the filtration system where they are captured rather than destroyed.

Here is a close look at the different types of active and passive air purifiers available.

Active Air Purifiers

There are several different types of active air purifiers which all work at destroying airborne contaminants.

• Ionizers: Ionizing air purifiers release either positive ions, negative ions, or a mix of both into the room. These ions then bind to molecules in the air to destroy them, and while good at reducing odors and destroying allergens, they are not effective in trapping cat hair.
• Ozone Generators: Ozone is also good at cleaning the air as it chemically reacts with airborne particulates to produce water and carbon dioxide. Unfortunately, ozone is also dangerous to human health if inhaled in large quantities.
• UV Light Purifiers: These air purifiers emit UV light which destroys contaminants in the air. However, these only work at destroying pathogens and microorganisms such as viruses, bacteria, and mold, and cannot capture cat hair or allergens.

Therefore, while active air purifiers are effective in destroying airborne bacteria and microbes, they are not ideal for eliminating allergens, cat hair, or dander. Of all three, ionizers are most effective as they can reduce pet odors and dander, but will still fail to reduce the pet hair in your home.

Also, whereas ozone generators are the most detrimental to human health, both ionizers and UV light purifiers release small quantities of ozone. While in small quantities ozone will not pose much risk, those with respiratory conditions could have adverse effects when inhaled. With all this in mind, active air purifiers are a worse option.

Passive Air Purifiers

You can also purchase several different types of passive air purifier, but the thing these all have in common is that they capture rather than destroy contaminants through a filtration process.

• HEPA Air Purifiers: HEPA air purifiers for cat allergies are the most common and effective option. A HEPA air filter is made from a fiber-like material with tiny holes in its surface, acting as a super fine sieve to trap particulates. The best HEPA filters can capture particles as small as 0.1 microns, so always opt for True HEPA over other types.
• Other Filter Types: You can also buy air purifiers that have filters made from polyester, fiberglass, and other materials. The holes in these filters are larger and so let more particles through, and are often used as pre-filters in HEPA air purifiers. These may let allergens through, but they are ideal for trapping cat hair.

All of the products I have recommended are passive air purifiers, as these are the best at capturing allergens, cat hair, and dander. However, certain active features can be combined with a passive purifier, such as Hathaspace Smart True HEPA Air Purifier which combines passive purification with ionization and an antimicrobial coating.

How Else Can I Reduce Cat Hair & Allergies?

It is normal for cats to shed as they are removing dead skin cells from their body. If left on their skin, this can cause irritation, and so shedding is a normal and necessary part of a cat’s life. In fact, if your cat is not shedding, this is more likely a cause for concern.

Some cats will shed more hair and dander than others, which will depend on the breed as well as whether they are indoor or outdoor cats. Yet, no matter whether your cat sheds a lot or a little, the chances are it is frustrating, time-consuming to clean up, and potentially allergy-causing.

Aside from buying an air purifier for cat allergies and pet hair, there are also several other things you can do to help combat these issues.

Create a Cat-Free Space

If you do suffer from allergies like me, you may need to create a cat-free space in your home. This ideally should be your bedroom where you need the air to be free of allergens so that you can get a peaceful night’s sleep. It can be tempting to want to snuggle up with your cat in your bed, but keeping them out of the room is a small price to pay for no more allergies!

If you can’t bear to lock them out altogether, at least stop them from sleeping on your bed. You should also get into the habit of washing your bedding regularly on a hot wash to destroy any allergens on there for when they do sneak up when you’re not looking!

Vacuum Regularly

When you have a cat, you need to get into the habit of vacuuming everywhere. Yes, this means your carpets and floors, but also your furniture. Vacuums are great at sucking up pesky cat hairs, but if you invest in a high-grade HEPA vacuum they can also do a good job at capturing allergens and dander too.

If you have a handheld vacuum for cat litter, this can double up as a vacuum for cat hair. Run it over the areas your cat loves to hang out, such as their favorite perch, the top shelf of your bookcase, or your couch. This is often much more convenient than having to pull out your household vacuum daily and is a worthwhile investment, especially if you have a long-haired cat or suffer from severe allergies.

Bathe Your Cat Regularly

You could also try bathing your cat regularly to reduce the amount of cat hair and dander that is released into the air. When bathing your cat, ensure you only use a shampoo that is intended for pets that is non-toxic, and if you have a kitten, you may need a special shampoo safe for kittens.

Cats are naturally clean themselves, so don’t overdo the washing. Ideally, you should be bathing your cat once every 3 to 6 weeks.

Brush Your Cat Regularly

What most cat owners forget is how crucial it is to brush your cat, regardless of whether you suffer from allergies or not. Felines might be notorious groomers, but they still need your help to maintain that fabulous fur. Short-haired cats require brushing at least one to two times per week, while medium and long-haired cats need brushing every single day.

If you want to reduce hair around the house and help your allergies, you should find the proper tools for brushing and combing. Consider the length of your cat’s fur when choosing a tool. The best brush for cats with long hair is not the same as the best brush for short-haired breeds. Also consider how comfortable the brush is, both on your cat’s skin and for you to hold.

Even if your cat is scared to death from these tools, brushing is still an option – you can purchase special brushes for cats that hate to be brushed. In addition, you can also learn a few tips and tricks to approach your furry friend and perform an entire brushing session with ease.

Keep Your Cat Hydrated

The dryer your skin, the more likely it will shed. When it comes to cats, this is no different. If your cat is not properly hydrated, it may be shedding dead skin cells and hair more than it should be.

Therefore, you can also reduce the amount of shedding by keeping your cat hydrated. Cats can typically be fussy drinkers, so be sure to replenish their water regularly so that it is clean and fresh. You may also find your cat’s water intake increases if you try swapping from a regular water bowl to a cat water fountain.

This is an effective solution as many cats prefer running water over still water. There are many potential reasons for this, but the common opinion is that cats used to drink from running water sources before they were domesticated, so now it’s a part of their genetic evolution.

Stainless steel cat water fountains are an excellent solution for felines who don’t even want to think about drinking water on a daily basis. They’re the most hygienic option, are easy to clean, and are less likely to cause issues to cat fur and skin. In addition, they’re significantly more durable and don’t retain unpleasant smells. They might be a little costlier than plastic fountains; however, they’re worth every dollar.

If you have tried these fountains and still wonder how to force a cat to drink water, you can also try to add some flavor to the water. It can be the juice from the can of wet food you just opened or a little bone broth. Just be sure you don’t add too much or use a liquid that’s rich in salt.

FAQs

Q: Do air purifiers help with cat hair?

A: Yes, air purifiers help to remove cat hair and dander from the air you breathe. However, they can only remove the hair floating in the air, but not once the pet hair has settled on your furniture. However, if you catch the cat hair before it settles, there will be a huge reduction in cat hair around your home as a whole.

Q: Are air purifiers safe for cats?

A: Yes, air purifiers are safe for cats, and will actually benefit them as well as you, as the gadget will clean the air that your both breathe. If your cat has allergies or asthma, they can be even more beneficial.

Q: Do air purifiers help with cat allergies?

A: Yes, cat allergies are predominantly caused by dander, and air purifiers will successfully catch dander and other allergens in their filters. Removing these from the air, your allergies will improve.

Q: Do air purifiers help with pet smells?

A: Air purifiers can help with pet smells such as litter box odors and other unpleasant scents, but it depends on the filter used. HEPA air purifiers with an activated carbon filter are the most effective at removing pet smells, so if you want your air purifier to remove odors, opt for these filters.

Q: Are cat allergies caused by cat hair?

A: No, most cat allergies are caused by dander. This is microscopic pieces of dead skin that fall off with cat hair as it sheds. This is often why people assume they are allergic to cat hair when it is the dander that is also falling off that is triggering an allergic reaction.

Q: Where should I place my air purifier?

A: If you are targeting a specific source, such as an air purifier for litter box dust or odors, then place it nearby. If you wish to clean the air in the room as a whole, it doesn’t matter where you keep the unit, as long as it is not near open windows. Also, gadgets that take in air 360 degrees can be placed anywhere, whereas air purifiers that have an intake at the front of the machine should not be placed in a corner or behind furniture.

Q: How long should I run an air purifier for?

A: Keeping your air purifier running permanently will ensure you have clean air all the time, but the filters will need replacing more frequently and it will use more energy. As a minimum, you should have your air purifier running for at least 12 hours per day, especially on days when  you’re at home.

Q: What is the best air purifier for cat hair?

A: In my opinion, the best air purifier for cat hair is the LEVOIT Air Purifier for Pets & Allergies. This product has a three-stage filtration process to capture cat hair, dander, odors, and allergens and runs whisper-quiet. My air is cleaner, my allergies are gone, and the amount of pet hair reduced!

Q: How often do HEPA filters need to be replaced in an air purifier?

A: True HEPA filters will need to be replaced at least once per year if they are to continue working effectively. However, this does depend on how much air they have processed and how dirty the air was in the first place. The more you use your machine, the more quickly the filter will need replacing.

Q: What is the difference between an active and a passive air purifier?

A: Active air purifiers emit ions, ozone, or other particles to bind with and break down airborne contaminants such as bacteria, viruses, and odors. Passive air purifiers work more like a sieve and capture rather than destroy particles and airborne contaminants.

Q: Will an active air purifier work for cat hair?

A: No, active air purifiers only work to destroy particles on a molecular level, so while they are partially effective in destroying pet odors and dander, they cannot get rid of cat hairs. For this, you will need a passive air purifier.

Q: How can I get rid of cat hair everywhere?

A: Getting an air purifier can capture cat hair when it is in the air, reducing the amount in your home. You can also brush and bathe your cat regularly, keep them hydrated so their skin is not dry and will shed less, and purchase a handheld vacuum to easily clean up any remaining hair.

Q: Is my cat shedding too much fur?

A: All cats will shed different amounts, but one way to tell if your cat is shedding too much is to check if their coat is thinning or if they have bald patches. If so, they are likely shedding too much. Also, look out for excessive hairballs, as if your feline frequently vomits up hair, they could be ingesting excess.

MY FINAL THOUGHTS

Regardless of whether you wish to simply remove cat hair from your home or whether you’re trying to also combat allergies and pet odors, having an air purifier is a fantastic solution.

Remember, a HEPA air purifier for cat allergies is the highest level of filtration possible, so where possible opt for these. Having a pre-filter to trap cat hair is also great to prolong the life of the HEPA filter, and an activated carbon filter will remove odors. A combination of these passive purification processes with active methods can work, but ionizers or ozone generators alone will not be successful for cat hair.

Hopefully, this information and these product reviews and recommendations will give you a great starting point in finding the perfect gadget for you. Purchase an air purifier today and say hello to a cat hair free and odorless home while keeping those sneezes at bay!
