Cats and dogs bring a lot of joy to our lives, but they also bring fur, dander, and odor along with them. Pet hair and dander can be a serious allergy trigger, even disrupting sleep and causing asthma complications. Air purifiers with certain features can remove pet-related allergens from the air, easing or even eliminating pet-related allergy symptoms and odors. 

We have found the best air purifiers for pets, ranked from one to six. The first three picks are excellent, the fourth and fifth are good but have more “cons, and the sixth is an example of what not to choose for pet-related purposes.

AirHonet’s Best 6 Air Purifiers for Pets – Reviewed

🏆 The Top Choice: Winix 5500-2 Air Purifier

winix 5500 2 front

Product Award:  Best Air Purifier for Pets


  • True-HEPA filter
  • Activated carbon filter
  • Auto mode
  • Air quality indicator 
  • Sleep mode

Why is this the Best Air Purifier for Pets?

The Winix 5500-2 gets the top spot because it has true-HEPA filtration, an activated carbon filter, and a pre-filter. The pre-filter catches pet hair and large dust or dirt particles your furry friends drag into the house. The AOC (carbon) filter absorbs pet odors, and the true-HEPA filter catches irritating dander. 

As well as the ideal trio of filters, this model for medium rooms also has functional features such as an auto mode which increases the fan speed when extra pet allergens are detected. It has a sleep mode that dims the lights and uses the quietest fan speed. This means that you get everyday functionality that fits into your 24/7 routine as well as effective filtration.

The rave reviews and countless customers reporting reduced odor and pet-related allergy symptoms make this classic model a clear winner. 

Note that this does include PlasmaWave technology which may emit small amounts of ozone, however, we don’t see this as a “con” as you can switch it off and forget about it. 

The filters are reasonably easy to maintain, with a washable pre-filter and carbon filter. However, the carbon filter does need to be replaced every few months, and the true-HEPA needs to be replaced each year. Replacement filters come in handy packs from Amazon, so sourcing them is easy.

This Air Purifier is Good For:

✔️ People who use an air purifier in their bedroom at night
✔️ People who want a hands-off operation with Auto mode
✔️ People who want the option of an ionizer

The Runner Up: Levoit LV-PUR131

levoit lv pur131 product

Product Award:  Best Quiet Air Purifier for Pets


  • Pre-filter
  • True-HEPA filter
  • Activated carbon filter
  • Auto mode
  • 100% ozone free

Why is this a Great Air Purifier for Pets?

The runner-up is the Levoit LV-PUR131. This deserves a high spot on the list because it has the trio of filters required for excellent purification for pet-inhabited homes: pre-filter for fur, true-HEPA filter for dander, and carbon filter for odors. What’s more, it is affordable and has a cost-effective and simple upkeep routine. 

Another excellent feature is that it does not have any ozone-producing filters or technology. This is important when searching for air purifiers for pets, as ozone can be harmful to animals.

This model caters to medium rooms and offers a quiet operation great for apartments or bedrooms where you need peace. The CADR rating on this machine is not the best, as it will take about an hour to completely clear a 360 square foot room. However, if you have only one pet or your pets don’t shed drastically, this isn’t an issue. 

Like our top pick, this model features an Auto mode which changes the fan speed according to how contaminated the air is. This is handy for homes where pets are more active at certain times of the day as it can detect and catch kicked-up dander, dirt, and fur. 

Finally, the maintenance requirements are pleasantly simple and affordable. Just replace the HEPA and carbon filters every six months, (they come in one easy pack). 

This Air Purifier is Good For:

✔️ People who want an air purifier without an ionizer
✔️ People who want an easy, fuss-free maintenance routine
✔️ People who want to track the quality of the air in their home

Second Runner Up: Honeywell 50250-S

honeywell 50250 s product

Product Award: Best Low-Maintenance Air Purifier for Pets 


  • True-HEPA filter
  • Activated charcoal filter
  • High CADR for dust
  • No ozone 
  • Low maintenance costs

Why is this a Very Good Air Purifier for Pets?

Next is the Honeywell 50250-S. This gets a high spot on the list because it has a true-HEPA filter and a pre-filter which doubles as an odor-reducing charcoal filter. This covers pet hair, dander, and pet-related smells. This model doesn’t have any ionizers or ozone-producing features that can pose health risks to your pets.

This model for medium-large rooms doesn’t have the bells and whistles of other models. It doesn’t have different modes or an air quality indicator. However, not everyone requires these, they just want a reliable and effective filtration system. This product certainly delivers, all with a low price tag. 

One of the best things about this choice is that the air true-HEPA filter can last for up to five years, as long as it is regularly cleaned. This reduces overall maintenance costs.

This Air Purifier is Good For:

✔️ People who cannot/do not want an ionizer or ozone-emitting technology
✔️ People who want a long-lasting filter and low maintenance costs
✔️ People who have a lower budget

The Good But Not Great: BlueAir Classic 205

blue pure classic 205 product image 1

Product Award: Best Air Odor-Reducing Purifier for Pets


  • True-HEPA filter
  • DualProtection filter option for odors and harmful gas

Why is this an “Okay” Air Purifier for Pets?

The Blueair Classic 205 is fourth on the list. There are some great features such as the true-HEPA filter which removes 99.97% of particles as small as 0.1 microns. This is especially great for dander which has been broken up into tinier particles. The optional DualProtection filter is great for reducing odors and harmful gases in the home which may be a health threat to pets.

However, the Classic 205 gets a lower spot on the list because it has an internal ionizer which cannot be switched off by the user. Blueair does state that their products do not emit ozone, but customers have stated otherwise. It pays to err on the side of caution, especially with pets in the home, as ozone can be dangerous if not fatal. 

While the Classic 205 is designed to be WiFi compatible, many users have found this to be a slow and frustrating feature. In terms of maintenance, the filters must be changed every 6 months, and are fairly priced. This model does have some great highlights, but the “cons” put it lower on the list. 

This Air Purifier is Good For:

✔️ People who require an air purifier with strong odor-reducing abilities
✔️ People who aren’t concerned about ionizers or who have “mostly outdoor” pets
✔️ People who require extra protection against pet dander

BlueAir Pure Blue 211+

blueair pure blue 211 plus black product

Product Award: Best Dirt-Reducing Air Purifier for Pets 


  • Energy Star Rated
  • Carbon filter 
  • Multiple color choices

Why is this an “Okay” Air Purifier for Pets?

The Blueair Pure Blue 211+ is not a bad product by any means, but it’s just not the best choice for people with pets. The filtration is not true-HEPA, which means you may not be getting the utmost protection from very small pieces of dander. It could be a perfect choice for other purposes such as pollen allergies. 

Another reason why we have placed this low on the list is that it has a record of producing a chemical-like smell. While this can go away after a few days, some users have found that it is permanent. This could be distressing or dangerous for pets in the home, so it’s best to avoid such complications. 

If your pets regularly bring dust or dirt into the home but pet hair and dander is a minor problem, this could be a good choice. Customers have reported that the 360 filtration does help to reduce dust and visible particles.

This Air Purifier is Good For:

✔️ People with hypoallergenic or low-shedding pets
✔️ People who want to reduce visible dust or dirt bought inside by pets
✔️ People who want to reduce pet odors

Hamilton Beach TrueAir Pet 04384

hamilton beach 04383 product

Product Award: Best for Small Spaces 


  • Carbon filter partially removes odors
  • Small and compact
  • Can be placed vertically or horizontally

Why is this last on the list of the best air purifiers for pets?

Last on the list is the Hamilton Beach TrueAir pet 04384. You may be surprised to see a pet-specific product on this list. Despite the name, this model for small rooms has been criticized for not removing sufficient amounts of pet hair.

It might be fine for pets who shed minimally, but don’t rely on this for moderate-high shedders! This model is not Energy Star or AHAM certified, which places it low on the list. 

The filtration is not true-HEPA, which is another reason why it lands at the bottom of the list. Pet-inhabited homes need excellent protection, which means “the real deal” when it comes to HEPA filters. 

The filters need to be replaced every few months but are quite affordable. 

While this model is designed for small rooms, it’s not ideal for bedrooms as it is reasonably loud and could disrupt sleep. Lastly, many customers have reported a burning smell coming from this model. While this may not happen to you, the risk is considerable. It’s best to avoid foul-smelling emissions from home appliances as some pets have very sensitive respiratory systems.

How To Choose An Air Purifier For Pets?

  • True-HEPA filter

A true-HEPA filter is your best bet for the most effective protection against pet-related allergens. A true-HEPA filter will catch 99.97% of particles as small as 0.3 microns in size. While pet dander is generally from 2.5 to 10 microns in size, particles can be broken into much smaller pieces. You should look for the best protection you can find, with means true-HEPA. 

  • Carbon filter 

Look for an air purifier with a carbon filter, also known as activated charcoal. These will absorb pet-related odors, helping to keep your home smelling fresh. This will also help to reduce your cleaning and home maintenance chores as you won’t be battling “pet smell” as often. 

  • Pre-filter 

A pre-filter is very handy when it comes to air purifiers for pets. The prefilter catches the largest particles, especially pet hair. By catching fur and fuzz, the pre-filter allows the HEPA and carbon filters to remain clearer and cleaner for longer. 

How Do Air Purifiers Help With Pet-Related Problems?

Air purifiers use a fan to draw air into the mechanism. Airborne allergens such as pet hair, dander, dust, and dirt your pet has bought inside will be drawn into the machine. The pre-filter catches large allergens such as pet hair, while the true-HEPA filter catches smaller particles such as dander.

An activated carbon filter will absorb odors, leaving the air fresher. Clean, allergen-free air is then sent back into the room. This process can alleviate pet-related allergy symptoms, and help your home to be fur-free and smelling pleasant. 

5 Tips For Taking Care of Pet Odors at Home

  1. Keep your pet’s bedding and blankets clean, as they can often create more odors than the pets themselves. Warm-wash them with natural detergent (to protect your pet’s skin) and leave to dry thoroughly. 
  2. If your pets are often rolling, playing, or even have the occasional “accident” on your carpets, get them steam cleaned twice a year.
  3. Use baking soda to quickly remove sudden spills, accidents or particularly noticeable odors on carpets. A simple solution of vinegar and baking soda is effective on odors when sprayed onto fabrics and carpets (try a patch test first)
  4. Open windows and doors daily to ensure sufficient airflow through your home 
  5. Bathe your dog/s regularly and when you notice an increase in odor. Use a natural, gentle shampoo to avoid irritating your dog’s skin and therefore increasing dander and hair shedding

Frequently Asked Questions

Are air purifiers safe for pets?

Yes, they are safe for pets as long as no ozone is emitted. Some air purifiers are a little less stable in their construction so do pose a risk of falling if you have very rowdy pets running around. If so, choose a model with a very sturdy, stable construction or one which can be wall-mounted.

Do air purifiers remove hair from carpet and furniture?

No, air purifiers only remove pet hair from the air. You must use an effective vacuum cleaner with a true-HEPA filter and a carpet brush to remove pet hair from carpets. When vacuuming, turn the air purifier up to the highest speed to catch any disrupted fur or debris.

Do ionizers harm pets?

Ionizers emit small amounts of ozone into the air. This can be dangerous for pets, and can even prove to be fatal if there are high enough amounts of ozone present. If you have pets at home, it’s best to avoid ionizers and ozone-emitting technology altogether. 

Do air purifiers help with pet-related allergies?

Yes, if the filters are properly maintained, cleaned, and replaced. An air purifier with a pre-filter and true-HEPA filter will effectively remove pet hair, dander, dust, and saliva-coated cat fur from the air. This helps to reduce pet-related allergies.
