Living with a pet means coexisting with any allergies, hair everywhere and unwanted smells — from litter boxes to bad breath.
Pet odors, hair and dander can linger, even with regular grooming and cleaning. That’s when an air purifier can become a valuable investment.
But that is only the case if you buy the right air purifier.
You should focus on finding a model that comes with a removable pre-filter (ideally washable), activated carbon filtration (for odors), a high quality particle filter (for allergens), good performance at quiet fan speeds, a control panel with the option to lock all buttons, and enough power to change the air 4-5 times per hour.
I kept all that in mind when shortlisting the air purifiers for this list. As always, I have bought and tested all these devices myself, so everything I’ll share is based on my experience and first-hand data.
I also made a point of sticking to air purifiers without an ionizer or with bipolar ionization technologies that could be disabled without negatively impacting air cleaning performance.
1. Best for large spaces: Levoit EverestAir
The EverestAir boosts power and smart features in a sleek white and silver design that makes it stand out from the crowd.
💡exclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
For $499.99, you get a good looking air purifier with enough air cleaning power (PM1 CADR of 375 cfm) to provide five air changes per hour in rooms up to 562 sq. ft. when running at top speed (57.8 dBA).
The pre-filter is easy to remove so you can vacuum pet hairs and extend the life of the main particle filter that sits behind it.
The bonded filter has a high quality particle filter on one side (to remove the smallest of particles from the air) and a gas filter on the other with 400g of pelleted activated carbon (to adsorb odors and gases).
The air quality sensor displays particle readings on screen and it unlocks a smart mode where it adjusts fan speeds automatically.
The color-coded LED lights on the display show the percentage of clean air in the room.
And the VeSync app unlocks features like scheduling and display lock to ensure curious pets don’t change settings.

2. Best for smelly pets: Alen BreatheSmart 75i (with the Fresh Filter)
A large air purifier with an H13 HEPA filter and 3.6 lbs of pelleted activated carbon to remove unwanted pet smells from the air.
The 75i is Alen’s largest and most powerful air purifier. With an estimated PM1 CADR of 333 cfm, it can provide five air changes per hour in rooms as large as 448 sq. ft.
Similarly to the EverestAir (above), the 75i comes with a removable pre-filter, which is easy to access and keep clean regularly.
It also has a laser particle sensor (which you won’t need to clean regularly) and you get an air quality indicator on screen.
There are multiple filter options available. For pets, I recommend the Fresh filter, which comes with a HEPA H13 and a carbon filter.
Alen’s Fresh filter is packed with 3.6 lbs of pelleted activated carbon, which is a lot more than what you get with most other devices.

3. Best under $200: Levoit Vital 200S
For less than $190, you can get an excellent air purifier with a removable pre-filter, carbon filtration, quiet operation and smart features.
This has been my top recommendation for most people since 2024 because it is affordable, performs as well as much more expensive units and comes with all the smart features readers ask about. It also has an estimated PM1 CADR of 260 cfm, it can provide five air changes per hour in rooms no larger than 390 sq. ft.
The Vital 200S comes with a washable pre-filter that will make it a lot easier to regularly remove pet hairs before they obstruct airflow.
You also get a bonded particle and carbon filter, which has enough carbon to help with mild pet smells but won’t be enough in cases where you’re dealing with serious odors.
In terms of air cleaning, it outperformed more expensive devices like the Winix 5510 and the Coway Airmega 250S, while generating less noise.
The control panel is simple and easy to figure out without reading the manual. You get a button to activate the child lock and you will also see a color-coded ring that shows air quality in real-time.

4. Best for small spaces: Levoit Core 400S (with Smoke Remover filter)
A smart and quiet air purifier with a filter packed with 450 grams of pelleted activated carbon to help with pet smells.
💡exclusive code for HouseFresh for 10% off a single purchase on Levoit.com: HOUSE10
There are many other much smaller devices than the 400S, but if you want to keep your air clean of pet hair, dander and odors, then you shouldn’t go smaller than this. The cylindrical design will make it easier to find a spot for it even in the smallest of rooms.
Even though you’ll see there’s a Pet Allergy filter, I recommend choosing the Smoke Remover filter as it comes with 50 grams more of carbon.
The filter itself is a cylindrical filter, so vacuuming the pre-filter won’t be as easy as with rectangular models like the Vital 200S.
Size-wise, the Core 400S is similar to the Winix T810 but it offers better air cleaning performance at quiet fan speeds that won’t disturb your pet.
Based on our tests, we estimate a PM1 CADR of 213 cfm, it can provide five air changes per hour in rooms up to 319 sq. ft.

5. Best for homes with multiple smelly pets: Austin Air Healthmate
An air purifier made in the USA with a filter packed with 15 lbs. of carbon that can remove the most stubborn, pungent pet odors from the air.
If you have multiple pets at home, you’re likely to need a lot more carbon than what you usually get with most air purifiers you’ll find in stores. For those cases, I recommend the Austin Air HealthMate and its filter packed with 15 lbs. of activated carbon and zeolite.
Its metal body is heavy but durable, with a flat top that many cats will enjoy sleeping on.
Even though it’s heavy, it comes on wheels so you can easily move it around your house as needed. It’s one of the only devices I’ve tested with wheels that roll well on carpets.
The filter inside the HealthMate is bigger than most small air purifiers you’ll see recommended online.
Instead of a touchscreen display or colorful buttons, the HealthMate comes with a dial to switch between three fan speeds — no risk of your pet accidentally switching the device off.

Special mentions
These are the air purifier models that nearly made the cut
I have tested over 130 different air purifiers and have found many excellent options for pet owners. Not all of them made my shortlist, but perhaps they will be a good choice for you.
Smart Air SA600
The SA600 has two H13 HEPA filters, two activated carbon filters, and two removable pre-filters. With a PM1 CADR of 249 cfm at top speed, it can change the air five times per hour in rooms up to 373 sq. ft.
It didn’t make this list because it’s too large for small spaces and too expensive ($279.95) for the under $200 category.
Alen BreatheSmart 35i
With a PM1 CADR of 162 cfm at top speed, the 35i cleans the air five times per hour in 247 sq. ft. rooms. You get different filters but for pet owners, I recommend the Fresh filter (H13 HEPA + carbon pellets).
Even though its performance is top-notch, it is more expensive than the Core 400S, which is my top pick for small spaces.
Dyson Big+Quiet BP06
It has a PM1 CADR of 198 cfm at top speed, so it can provide five air changes per hour in rooms up to 297 sq. ft. It has an H13 HEPA filter for pet allergies and a wraparound filter with 900g of carbon for pet odors.
The BP06 is the best Dyson air purifier I’ve tested, but I haven’t included it because it’s expensive ($800+) and keeps going out of stock.
Coway Airmega 150
The Coway 150 has the most convenient pre-filter design for pet hair: you can remove it without opening the device AND is washable.
With a top speed PM1 CADR of 156 cfm, it can clean the air five times per hour in 234 sq. ft. spaces. It has solid particle and carbon filters, but the Core 400S offers higher performance and more carbon.
AirFanta 3Pro
This PC fan-powered air purifier offers incredible value for money, costing $164.99 and offering an impressive PM1 CADR of 353 cfm. At top speed, it can clean the air five times per hour in spaces up to 529 sq. ft.
It didn’t make the cut because the fans on top are too exposed and the design might not survive being pushed around by curious pets.
Coway Airmega 250S
This is a beautiful device from Coway that doesn’t have an ionizer and comes with a smart, easy-release pre-filter like the Coway 150.
We estimate a PM1 CADR of 249 cfm, which can provide five air changes per hour in rooms up to 373 sq. ft. I didn’t include it because it costs upwards of $400 but offers less power than the cheaper Vital 200S.
What to look for when buying an air purifier for pets
To find out if the unit you are considering is the right one for the job, these are a few questions that will guide you in your search:
1. Does the air purifier have the right filters?
When it comes to pets, a three-stage filtration system is the most comprehensive option, as it includes a pre-filter, an activated carbon filter, and a particle filter.
- Stage 1: Pre-filter. These are designed to pick up larger particles (such as pet hair) before they reach the main filter. Their key function is to prevent fur from clogging the main filters, thus extending their lifespan. Removable pre-filters are more straightforward to clean; some are washable to rinse the shed fur effortlessly.
- Stage 2: Activated carbon filter. This is the layer that clears the air from unwanted pet odors — the carbon works by absorbing odors (and VOCs) that pass through the filter, removing them from the air.
- Stage 3: Main particle filter. Particle filters are made of pleated sheets that create a maze of randomly assorted fibers capable of capturing the smallest of airborne particles, including pet dander, dust, and pollen.
2. Is the air purifier capable of dealing with your room size?
This is a key issue when choosing the right air purifier for you. A unit suited for smaller rooms won’t be able to make the air changes per hour (ACH) needed to clean the air in large spaces. Therefore, it won’t be efficient at removing the odors and lacks the power to remove all airborne pollutants.
This is where the unit’s CADR (Clean Air Delivery Rate) comes in, indicating its cleaning performance in CFM (Cubic Feet Per Minute). We’ve included each unit’s CADR and room size recommendation in our spec tables.
But you can use our calculator to find the exact CADR you need based on the size of the space where you want to use the air purifier:
3. Does the unit produce any chemical by-products?
Ionization features are often found in air purifiers to enhance their performance. Air purifiers with ionizer functions release ions into the air that attach to airborne particles, forcing them to drop onto surfaces so you can vacuum and wipe them.
The problem is that, in the process, these devices can generate small amounts of ozone, which can be detrimental to the health of those with pre-existing respiratory conditions.
If you worry about the health of your pet, then you should stick to air purifiers without ionizers or with ionizer functions that can be disabled, like the ones on my list of recommendations.
To wrap it up
Taking good care of your pets (with frequent grooming, healthy food and periodic visits to the vet) is a solid step forward in reducing their odor and the amount of hair floating around in the air. Regular home cleaning makes for another important element in the equation, but that’s not always enough.
Introducing the right air purifier to your home can make a BIG difference. Just make sure you are buying a device powerful enough for the space where you will place it with a high quality particle filter, a pre-filter that is easy to clean, and a good amount of pelleted activated carbon to deal with odors. Pay attention to sound levels too, as pets are sensitive to noise, and stay away from ionizer functions that cannot be disabled.
