Verified Review: Our Hands On Experience

We don’t like to recommend products without giving them a try first. During the research stage for writing this review, we purchased a large number of air purifiers to test. The products featured below represent our top picks, and we liked the way they performed better than the other models we tried. Here are a few additional observations we had for each model:

  • LEVOIT Air Purifier for Home: We were impressed with how effective this unit was at eliminating pet odor smells around the litter box area. We also like how quiet the low speed is, and that it allows the machine to operate in the background without causing any disruptions. However, the higher speed was a bit louder than we’d like.
  • Winix 5500-2 Air Purifier with True HEPA: In our home with multiple dogs, we found that this really helped to eliminate that ‘dog smell,’ and were very pleased with the results. However, we didn’t realize how expensive the replacement filters were going to be.
  • Coway Airmega 400 Smart Air Purifier: We were pleased with a lot of the special features on this filter including the washable filters (pre-filter), timer settings, and indicator lights. However, given how large the unit is, we wish it had wheels to make it easier to move around.

Buying Guide for Air Purifiers for Pets

There are a few different considerations to keep in mind as you are shopping for an air purifier for your pets. Using these considerations to guide your search can help ensure that you end up choosing the best product that will meet your needs.

Coverage Area

First, you’ll need to consider the size of the space where you plan to put the air purifier. Different air purifiers offer different capacities, and some are only designed for smaller spaces. Determine the number of square feet in your space, and choose an air purifier that will be strong enough to work in that space.

If you’re looking for a portable filter to move between spaces in your home, choose one that has a large enough capacity for the largest room where it may be used.

Sound

Next, be sure to check the volume for each air purifier you’re considering. Some models are much noisier than others, and depending on where you plan to put the air purifier, could be too loud. Some pets are also more sensitive to sounds, so if this is true for your dog or cat, look for an ultra-quiet air purifier or one that includes quiet modes.

Additional Features

Some manufacturers include additional features with their air purifiers. These may include temperature settings and enhanced odor-eliminating filters. Washable filters are another feature you may want to look for. Washable filters can reduce the overall cost of owning the air purifier since you won’t need to purchase new filters.

You may also want to consider the aesthetic appeal of each air purifier, especially if it will be going in a main living area in your home. Some air purifiers also include different lighting options, which may add to their aesthetic appeal.

Budget

Finally, keep your budget in mind. Are you looking for a more economically-priced option, or are you in a position to splurge a bit and choose an air filter that offers all the bells and whistles?

The Best Air Purifier for Pets: Reviewed for 2021 FAQs (Frequently Asked Questions) 

What are the best air purifiers for a house with pets?

The best air purifier for homes with pets will vary depending on your exact needs. For example, large rooms will require a more powerful air purifier than small rooms will. Whether you’re looking for odor control, relief from allergies, or both, different air filters may offer a better solution. Some are designed more for pet odors, while others have special filters better at filter hair and dander for pet allergies and asthma relief.

Our favorite air purifier for homes with pets is the LEVOIT Air Purifier. We also liked the Winix 5500-2 Air Purifier and the Coway Airmega 400 Smart Air Purifier.

Do air purifiers really work for pet dander?

Some air purifiers can help reduce pet dander. Choosing an air purifier that features a HEPA filter will be the most effective in this regard. Pet dander typically has a width between 5 and 10 microns, and HEPA filters can remove particles that are as small as 0.3 microns from the air.

Does an air purifier remove the dog smell?

Yes, some air purifiers can remove, or significantly decrease, pet smells. HEPA air purifiers are most effective in this regard since they are able to filter much finer particles than other purifiers. Some air purifiers may include additional filters, often made with carbon, designed to trap odors for enhanced odor control.

Do air purifiers collect dog hair?

Air purifiers may remove some of the dog hair that is floating in the air, but they won’t prevent air from getting stuck on furniture or rugs.

Is an air purifier good for cats?

Yes, air purifiers can help with cat odors and dander. Some stronger air purifiers may help with pet allergies and asthma symptoms enough to allow individuals with mild allergies to still be in a home with cats. However, this will depend on the severity of the individual’s allergies.

What are the advantages of an air purifier if you have pets?

There are many different advantages associated with purchasing an air purifier if you have pets. These include:

• Reducing pet dander, hair, and odors
• Removing other allergens from your homes, such as pollen and bacteria, that could be irritating you or your pets
• Optional add-on features such as sleep modes, enhanced odor control, quiet modes, and indicator lights for filter changes
• Available in different capacities to accommodate large rooms and small rooms
• Some feature a portable design and can be moved between rooms in your home as needed.
