Why You Need an Air Purifier for Pets

Even though neither you nor your family members have any pet allergies, a few things could still be harmful. One major air pollutant caused by pets is dander. Most people blame pet hair for allergies, but that’s not always true.

Pet dander is microscopic protein flecks shed by the pet’s skin. As your pet cleans themselves by licking or scratching their skin, dander is released into the air and can be inhaled. This is also why getting a hairless dog or cat won’t necessarily mean it’s allergen-free (1).

Other pet allergens include urine, saliva and blood. Pet allergens spread easily through the air and are close to impossible to spot. These allergens also stick easily to surfaces such as carpets and furniture — even your clothes. Plus, they can stay potent for a long time (2).

Inhaling pet dander or other allergens can cause coughing, sneezing or wheezing, even if you don’t have allergies. Vacuuming your house regularly can help to keep these allergens at bay, but it isn’t always enough.

How Will an Air Purifier Help?

Air purifiers work by drawing in air and filtering it through different stages (depending on the model). Once the air is filtered, it’s released back into the room for you to enjoy.

Most air purifiers use a two-stage filter or more. This includes an activated carbon filter and HEPA filter. Some purifiers will also have a pre-filter that captures larger particles.

The activated carbon filter will absorb odors and even chemical vapors and VOCs. These filters will usually capture particles in sizes from 0.5 to 50 microns (3).

HEPA filters are more thorough at capturing small particles such as dust mites and pet dander. However, these vary significantly depending on the type. A True HEPA filter will remove up to 99.97 percent of all pollutants as tiny as 0.3 microns.

Take Note

True HEPA filters are a must if you have any allergic symptoms caused by a pet. HEPA-grade or type filters aren’t as thorough and will only capture about 99 percent of pollutants. This may not be enough to catch dander, so it leaves the risk of allergic reactions.

If you do not have any allergic effects from your pet, you can easily go for a HEPA-grade filter. This will remove larger particles such as hair and dust, giving you a cleaner home environment.

Finding the Best Air Purifier for Pets

A HEPA filter and an activated carbon filter are important in an air purifier for pets. These will remove unpleasant odors, hair and even dander. But, there are also a few other things you should consider before buying the best air purifier for pets.

Size and Location

The size of the unit is probably the first thing you should consider. Air purifiers come in a range of sizes, and the size usually determines how big of an area it can cover.

Smaller units will usually cover up to 360 square feet, with some only covering 100 square feet. This is due to the size of the fan and filters.

Before deciding on an air purifier, therefore, consider the size of the room it’s going to be covering. Is it for the bedroom? A nursery or office? Or is it going to be cleaning the air of your spacious living room?

Small air purifiers are easily located on a table, shelf or kitchen counter. Large units need more clearance (usually two feet between the unit and walls). These are generally placed next to a sofa or in a corner.

Settings and Modes

Most air purifiers on the market are fitted with different modes and settings to make things easier for the user. These often include sleep modes and auto modes. Some will also have a filter replacement indicator.

An auto mode is very useful for when you’re not sure how polluted your indoor air is. The unit will use special sensors to monitor indoor air quality and then set the fan speed to best suit it. Some units will even notify you via a color-changing LED light on the display.

Sleep modes will lower the fan speed to a minimum, which also reduces sound levels. Some units have nightlights as well, which are handy in nurseries or kids’ rooms.

However, the nightlight feature is often criticized because there tends to be no way of turning it off. It’s also usually too bright. So if you fall for an air purifier that features a nightlight, make sure it has the option of being turned off or on.

Washable Pre-Filter

Pets are generally covered in fur, which they shed at different points in their lives. This shed will often linger around in the air, on furniture, and on clothes.

Pre-filters are excellent at capturing large particles and hair, but they can quickly get clogged. So having a washable pre-filter is the best option for long-haired pet owners. Whenever you feel like the efficiency is reducing, check the pre-filter and give it a rinse.

The Best Air Purifier for Pets of 2021

When searching for the items on our list, we considered the above points. We then researched real customer reviews from pet owners to see how the units stood against the task. With some extra helpful input from our expert team, we found the best air purifiers for pets.

1. Medify MA-50 H13 HEPA Filter

For large rooms that need purified air, the Medify MA-50 Air Purifier is where it’s at.

Fitted with a three-stage filtration system, this air purifier will capture anything from large particles of pollen to fine hair. The higher-grade HEPA filter which is ranked even higher than True HEPA filter will remove even the tiniest particles triggering sneezes or coughs from you.

The MA-50 has a few great features to offer as well. It comes with dimmable control light.

Why We Love It

Medical-Grade Filter

We all love our pets unconditionally, but unfortunately, allergies happen. If you’re feeling extra sniffly or itchy, your pet might be shedding. Pet dander could also be causing an unpleasant reaction.

The higher-grade True HEPA filter in this purifier is classified as an H13. This is one of the most efficient HEPA filters available. It will capture pet dander, hair, smoke and fine hair. Better still, it will remove bacteria and viruses from your air.

Eliminates Odors

If your kitten’s litter box is stirring up a stinky storm, this purifier will come to the rescue. Place it in the same room, or the next, as the box and set it to auto mode. The purifier will monitor the quality of the air and adjust the speed of the fan accordingly.

Cleans Large Rooms

In about 15 minutes, this air purifier will clean a room of up to 550 square feet. It will take only half an hour to clean the air of a room of 1,100 square feet. What an efficient way in getting rid of the stink!

Child-Lock Features

This unit is safe even with toddlers at home because of its child-lock safety features.

Keep In Mind

Expensive Filter

Anything worth having comes with a price. Truly, while it may require you to shell out money for filter replacement, you’d have peace of mind that you get to remove unwanted air particles such as viruses enabling you to protect your family because of its medical-grade filter. Now that’s priceless!

Additional Specs

Filtration Stages Three-in-one filter
Permanent Filter No
Fan Speeds Four
Room Circulation Per Hour Covers 550 square feet four times per hour
Recommended Room Coverage 1,100 square feet

2. Bissell MyAir Personal Air Purifier

Bissell is a leading brand when it comes to vacuums, carpet cleaners and formulas for pet messes — and now we can add air purifiers to the list.

The MyAir air purifier is a compact unit that fits perfectly on any bedside table or office desk. It uses a three-stage filtration system that effectively captures pet dander, hair and unpleasant odors.

We love this unit for its super-quiet operation and the optional nightlight that can be turned off. You get to choose between different modes to suit the room and air quality.

Because it’s a small purifier, it’s recommended to be used in smaller rooms of up to 100 square feet.

Why We Love It

Good for Bedsharing Pets

Who doesn’t like to snuggle up against their best bud at night? Want to enjoy a cuddle without dealing with hairy air? Feel free to run the purifier in the bedroom during the night and day!

Excellent Sleep Mode

When on Sleep Mode, the MyAir purifier will operate at a whisper-quiet level. It features a nightlight that can be turned off if you prefer to sleep in the dark. This is unlike other units with dimmed nightlights that can bother some users.

Easy Maintenance

The three-in-one filter is super easy to replace since there’s only one to worry about. You won’t have to guess the replacement time; the unit will notify you when it’s necessary. It’s also easy to remove.

Odors Will Be Gone

If you’re struggling with unpleasant odors caused by your pets, this purifier will take care of the problem. It’s fitted with an activated carbon filter that absorbs any odor in the room.

Compact Design

The small unit is only 8 inches in diameter and 12 inches high. It is the perfect size for bedside tables, kitchen counters, office desks and in nurseries or children’s rooms.

You can also take it with you when traveling as it fits easily in a suitcase. Then you can enjoy purified air when away from home as well.

Keep In Mind

No Medium Fan Speed

Although we love the compact MyAir purifier, we wish there was a medium fan speed. Now, you can choose between low or high, which is welcome. But something in between would be much appreciated.

Additional Specs

Filtration Stages Three-in-one filter
Permanent Filter No
Fan Speeds Two
Room Circulation Per Hour Not specified
Recommended Room Coverage 100 square feet

3. Winix HR900 Ultimate Pet Air Purifier

Best Five-Stage Filtration Air Purifier

The Winix HR900 was made to tackle common pet issues such as odors, dander and hair. It’s equipped with a True HEPA filter and a washable advanced odor control filter.

If one of your major issues is shedding hair, this will make a significant difference. As air is drawn in, the pre-filter will capture large hair. Meanwhile, the HEPA filter will take care of the smallest strands.

PlasmaWave Technology will break apart odors, chemical vapors and allergens before they have a chance at causing you harm. Plus, it’s safe to use and doesn’t produce any ozone.

Why We Love It

Intended for Pets

The thing that sets this purifier apart from others is that it was made for pet families. The pre-filter removes hair while the True HEPA captures pet dander and all of the fine strands that escape the other filters.

Bad odors such as kitty litter and dog urine will be quickly absorbed by the carbon filter. It’s easy to maintain and can be washed when needed.

Homeowners with multiple pets have only good things to say about this purifier. Many say it completely eliminates unpleasant odors and hair.

Excellent for Large Areas

This air purifier can filter the air of a room of up to 300 square feet. We think this is excellent for a medium to large-sized room. Although it’s rather big, it still looks sleek and modern and can stand subtly in a corner or next to the couch.

Eliminates Pollutants

PlasmaWave Technology breaks apart molecules such as odors and allergens. Because it attacks the particles at a molecular level, they’re broken apart and absorbed by the filter much quicker.

Monitor the Air Quality

Always know how polluted, or unpolluted, your indoor air is. The purifier will monitor the air and notify you via the color-changing light on the display.

Keep In Mind

Sleep Mode Is Less Efficient

When in sleep mode, the HR900 seems to be non-functional. The fan speed is very low, and it doesn’t give as much air either. This was a common complaint from multiple customers.

Additional Specs

Filtration Stages Five-stage
Permanent Filter Washable pre-filter and washable Advanced Odor Control carbon filter
Fan Speeds Not specified
Room Circulation Per Hour Not specified
Recommended Room Coverage 300 square feet

4. Winix 5300-2 Air Purifier

Best Pet Air Purifier for Medium-Sized Rooms

If you liked the Winix HR900 but want something that can take on a larger area, the 5300-2 is for you. It comes with four fan speeds, different modes and smart sensors.

The 5300-2 is further equipped with a three-stage filtration system. This consists of a pre-filter, carbon and True HEPA filters. Similar to the HR900, this unit also uses PlasmaWave Technology to break down odor molecules and allergens.

It’s suitable for rooms of up to 360 square feet and is nearly silent in medium, low and sleep mode. A downside to this purifier, however, is its size; it’s quite large and will take up significant space.

Why We Love It

Odor Eliminator

If you’re getting frustrated with the pet smell that seems to linger in your home, this will help. The three-stage filtration system includes an activated carbon filter that absorbs bad odors and VOCs.

If that’s not enough, the PlasmaWave will break down odors at a molecular level, destroying them before they settle. It does the same with viruses, bacteria and allergens. Winix claims it won’t produce any ozone, so you can use it with ease of mind.

True HEPA Filter

The True HEPA filter effectively removes up to 99.97 percent of pollutants found in the air. This includes dust mites, pollen, pet dander and allergens at the tiny size of 0.3 microns. It will also capture other harmful pollutants such as mold spores and organic chemicals.

Four Fan Speeds

You get to choose between four fan speeds to suit the room and air quality. The high and turbo settings are super-efficient and will draw in large amounts of air in one go.

Different Modes

When needed, you can set the purifier to specific modes to suit the room and time of day. There’s an auto mode that utilizes smart sensors to monitor the air quality and then set the fan accordingly.

Sleep mode is excellent for late nights. While you’re sleeping, it’s nearly silent, reaching only 27 decibels. There’s also no annoying lights that could disturb your sleep.

Keep In Mind

Replacement Filters Are Expensive

Unfortunately, when it’s time for a filter replacement, you may be in for a shock. The replacements are quite overpriced, which also put off several customers.

Additional Specs

Filtration Stages Three-stage
Permanent Filter No
Fan Speeds Four
Room Circulation Per Hour Not specified
Recommended Room Coverage 360 square feet

5. Levoit True HEPA Energy Star Air Purifier

Best Eco-Friendly Pet Air Purifier

Although air purifiers are a great appliance to have at home, they can draw a significant amount of electricity. However, with one like this from Levoit, you can have pure air and low bills.

Using only 40 watts, this air purifier is Energy Star certified. This means you can save on your bills and be more eco-friendly while breathing clean air.

The PUR131 is equipped with a three-stage filtration system that includes a carbon filter and True HEPA. It will quickly remove unpleasant pet odors, dander, hair, allergens, mold and other pollutants.

This purifier is best suited for medium to large rooms of up to 360 square feet. It’s excellent for living rooms, bedrooms and kitchens.

Why We Love It


This air purifier can clean a room of up to 360 square feet, 4.5 times per hour. Even if you have a hairy dog that’s shedding, the dander won’t be lingering for long.

The three-stage filtration includes a pre-filter, honeycomb activated carbon and True HEPA filter.

The pre-filter captures larger particles such as hair, dust and pollen. The True HEPA filter, on the other hand, takes care of tiny pollutants. Bad odors such as smoke, kitty litter and other smells will be quickly absorbed by the activated carbon filter.


You can set the timer to turn the unit off after a certain amount of time. Choose anywhere between one and 12 hours. This is an excellent way to save some extra energy.

Filter Replacement Indicator

The smart filter replacement sensor will calculate air quality, fan speed and run time to determine when a change is needed. It will then notify you on the display panel when it’s time to replace the filter. This feature is very helpful as it ensures the purifier is working at all times.

Optional LED Lights

For night use, having bright LED lights can be a major bother for many people. However, the PUR131 makes it possible to turn the light on or off as you like.

Keep In Mind

Humming on High Speed

Unfortunately, when at high speed, this purifier tends to make a humming sound that can be annoying.

Additional Specs

Filtration Stages Three-stage

6. Coway Airmega 400 Air Purifier

If you need an air purifier for a larger area, this will suit you. The Coway Airmega covers a whopping 1,560 square feet, cleaning the air twice per hour.

The purifier is fitted with a Max2 filter that combines activated carbon and True HEPA filters. It effectively removes airborne pollutants and odors that could be bothering you.

Despite the great coverage, it’s surprisingly sleek and not as cumbersome as similar units. Instead of drawing air in only from one side, this purifier is fitted with powerful dual suction to clean the air more efficiently.

Why We Love It

Amazing Coverage

If you live in an apartment or have a large living space, this will be the perfect addition. The broad coverage will effectively remove pet dander, bad odors and hair.

Air Quality Monitoring

Keep up to date with the quality of your indoor air. It monitors the air through different sensors and then notifies you through the LED ring on the front of the unit. Additionally, in auto mode, the purifier automatically adjusts the fan speed to accommodate the potential pollutants in your air.

Dual Suction

Unlike other air purifiers that only draw air in from the front, this one will draw air in from two sides. It then effectively lets clean air out from the top.

Filter Indicator

When it’s time to change the filter, a light on the display will light up to notify you. Filter lifespan is calculated based on how much air it processes.

Washable Pre-Filter

The pre-filter will capture all large particles of dust, pollen and hair. It’s easy to care for and can be washed when needed. Make sure it’s entirely dry when put back in.

Keep In Mind


This air purifier is quite loud; even when in sleep mode, it still makes a noticeable sound. It might be due to the size and strong dual suction.

Additional Specs

Filtration Stages Two-in-one filter and pre-filter
Permanent Filter Washable pre-filter

7. Hamilton Beach TrueAir Ultra-Quiet Air Purifier

Best Quiet Air Purifier for Pets

If you’re looking for an air purifier that’s affordable in the long run, the TrueAir is for you. It features a permanent HEPA filter that can easily be cleaned when needed. There are also two replaceable carbon zeolite filters that capture and absorb odors.

This air purifier was made with pet families in mind. It has a compact size and can be placed on the side or standing up. The TrueAir is best suited for smaller rooms of up to 140 square feet, but it’s still highly effective.

There are three speeds to choose from. The settings and dial-operation are easy to figure out and use.

Why We Love It

Easy Maintenance

HEPA filters can be pricey, but this purifier features a permanent filter that requires no replacement. When you feel like the performance quality is reducing, simply vacuum the filter and it will be good as new.

Two Carbon Filters

Pet odors won’t stand a chance against this purifier with two carbon zeolite filters. These effectively absorb bad odors and chemical vapors, leaving you with fresh air to inhale.


Air purifiers can be large and cumbersome which makes it difficult to find a suitable location. However, the TrueAir is compact and fits easily on a bedside table or on a shelf. It certainly doesn’t hurt that it can be placed either horizontally or vertically.

Keep In Mind

Not for Allergies

This purifier uses a HEPA-grade filter, not a True HEPA, so it will only capture up to 99 percent of airborne pollutants. It’s efficient for pet hair and odors, but if you’re dealing with allergies, we highly suggest you choose a different unit.
