Best Air Purifiers for Pets of 2022

Popular Air Purifiers

If you have pet allergies that leave you sneezing and experiencing respiratory symptoms, buying an air purifier may help you breathe easier. These devices are designed to clear the air of small airborne allergens and particles, improving air quality.

Before you purchase an air purifier, it is important to understand its limitations. If you have significant sensitivity to pet dander, these devices might not help. The Environmental Protection Agency (EPA) notes that “the evidence is weak” that these devices can reduce asthma symptoms associated with small particles such as airborne cat dander, for example.

But air purifiers can benefit those hoping to eliminate pollutants and some allergens and particles. We’ve researched a range of these devices and determined the Best Air Purifiers for Pets of 2022 for improving the air in your home through unbiased data analysis.

Choosing the best air purifier for pets and allergens comes down to selecting one that has a clean air delivery rate, known as a CADR. Making sure the air purifier covers the right area for the room where you intend to use it is one of the items to research before buying. A higher CADR results in a greater capacity to filter particles, which is necessary for larger rooms.

Typically, a high-efficiency particulate air filter – or HEPA air filter – is used to achieve a high CADR. To operate at their best, air purifiers also must be kept clear of curtains, furniture, or anything else that can block their airflow.

If you have pets in the house, the noise level could be a factor. When researching an air purifier, consider the decibels or dB(A) and how loud it will be, especially if it’s running all day and night.

If you have pets, you may have allergies to their dander or to the fur they shed. The highest-rated air purifier in the Best Air Purifiers of 2022 is the Coway Airmega AP-1512HH, but it is not the only option. Read on for details of what our data has determined to be the Best Air Purifiers for Pets of 2022.

The Honeywell HPA300finishes in a tie for fifth place in the Best Air Purifiers for Pets of 2022 category. It also places sixth in our Best Air Purifier for Large Rooms of 2022 category and ties for No. 7 in Best Air Purifiers of 2022 overall.

If you have a medium-sized room, the Honeywell HPA300 hits a “sweet spot” between most of the other purifiers on this list. It can handle rooms of up to 450 square feet and has CADR ratings of 300 (smoke and pollen) and 320 (dust). Its HEPA filter lasts up to 12 months.

A variety of different types of air purifiers are available, and each utilizes its own technology to improve the air quality in your home. Common types of air purifiers include those with different options in filters and technology.

  • Mechanical filters: HEPA filters that trap dust and allergen particles
  • Activated carbon technology: Filters that rely on activated carbon to capture air molecules that cause odors and may also have a pleated filter that traps particles 
  • Ultraviolet technology: UV radiation renders airborne viruses, bacteria, and fungal spores inactive
  • Negative ion technology: Purifies the air by producing negative ions that cause impurities in the air to clump together and attach to surfaces 
  • Ozone technology: Produces the molecule ozone, which then reacts with pollutants to change their chemical makeup. However, professional reviewers recommend against these types of machines, as ozone can be harmful. 

Air purifiers are typically designed to capture smaller particles and odors. But if you have a shaggy dog or fluffy cat, you may have larger strands of fur and hair occasionally floating through the air in your home.

Fortunately, many purifiers come with a pre-filter that captures bigger things in the air, such as fur from pets or hair from humans. These filters need to be replaced every few months.

As for pet dander, most air purifiers are built to remove this type of particle from the air.

Studies have found that air cleaners are “somewhat effective” in reducing allergy or asthma symptoms in some people, although improvements are modest, according to the Environmental Protection Agency (EPA). It is likely that some types of air purifiers do a better job of taming allergens than others.

For example, a 2009 study found a slight improvement in bronchial sensitivity in children with asthma who used an air cleaner with a HEPA filter. The Coway Airmega AP-1512HH, No. 1 in our Best Air Purifiers for Pets of 2022 rating, has a four-stage filtration, where the air is pushed through a pre-filter, a carbon filter, a HEPA filter, and a bipolar ionizer.

However, other purifiers might not be the best choice for reducing allergens. The EPA notes that purifiers that use UV technology have not been shown to be effective in reducing dust mite and mold allergens, or reducing symptoms of allergies or asthma.If you are having serious issues with asthma or allergy symptoms, you should always consult a physician to determine which air purifier, if any, is recommended for treating your symptoms.

The cost of an air purifier for pets varies depending on several factors. Most notably, you will pay more for an air purifier if you want one that has the power to purify a large room.

For example, the Coway Airmega 400 purifies a room that is up to 1,560 square feet in size. It costs $649. By contrast, the Coway Airmega AP-1512HH purifies a much smaller room, up to 361 square feet, and is far less than half the price, at $229.

Paying more for an air purifier doesn’t guarantee you will get a better product. The more affordable AP-1512HH is No. 1 in our Best Air Purifiers for Pets rating over its more expensive sister product, the 400. Also, remember that shopping around is a good way to get a deal, regardless of which model you choose.

If eliminating pet smells is your main goal, you might want to purchase an air purifier with technology specifically designed to eliminate odors. For example, some purifiers use activated carbon to capture air molecules that cause odors. Beware the cost of replacing activated carbon filters, however. Professional reviewers note that while other air purifier filters may last up to a year, activated carbon filters need to be replaced every three months and may cost as much as $50.

Also, know that some air purifiers, such as those with mechanical filters, like HEPA filters, may not be odor-eliminating at all.

Manufacturers such as Blueair note that most pet allergies are tied to the proteins found in pet saliva, sweat, and dander. These circulate in the air, causing issues for some people. Pets also can bring allergens into the home from outside.

Blueair and other companies say air purifiers with high CADR ratings can clean the air and reduce allergy symptoms.

Many medical professionals and other experts agree that air purifiers can help improve the air in your home, although they often stress that you should not expect dramatic results. The EPA notes that the best way to clean the air inside your home is to eliminate any sources of pollution and to ventilate the house with fresh outdoor air. But it adds that using an air purifier “can help to improve indoor air quality.”

The Centers for Disease Control and Prevention even notes that using portable high-efficiency particulate air (HEPA) cleaners may help reduce your risk of exposure to COVID-19.

Overall, medical professionals have differing opinions on the value of using air purifiers in the home. If you are considering making this purchase to improve your health, talk to a doctor to get a professional medical opinion on whether such a purchase makes sense.

Our 360 Methodology for Evaluating Air Purifiers

Why You Can Trust Us: 43 Air Purifiers Researched

At U.S. News & World Report, we rank the Best Hospitals, Best Colleges, and Best Cars to guide readers through some of life’s most complicated decisions. Our 360 Reviews team draws on this same unbiased approach to rate the products that you use every day. To build our ratings, we researched more than 43 air purifiers and analyzed 10 reviews. Our 360 Reviews team does not take samples, gifts, or loans of products or services we review. All sample products provided for review are donated after review. In addition, we maintain a separate business team that has no influence over our methodology or recommendations.

The following describes our 360 approach to researching and analyzing air purifiers to guide prospective consumers.

1. We researched the companies and products people care most about.

U.S. News analyzed and compared a variety of publicly available data, including internet search data, to determine which air purifier companies Americans are most interested in. We found 43 air purifiers that stand out in terms of volume of searches and research among consumers, as well as across the different rating sources.

We then compared the available air purifiers provided by our top air purifier companies across several criteria, including cost, CADR, room coverage, noise level, filter type, filter life, power consumption, fan speeds, and dimensions. Research shows that these are the most important criteria for people shopping for an air purifier.

2. We created objective 360 Overall Ratings based on an analysis of third-party reviews.

U.S. News’ 360 Reviews team applied an unbiased methodology that includes opinions from professional reviews as well as consumer reviews.

Our scoring methodology is based on a composite analysis of the ratings and reviews published by credible third-party professional and consumer review sources. The ratings are not based on personal opinions or experiences of U.S. News. To calculate the ratings:

(a) We compiled two types of third-party ratings and reviews:

  • Professional Ratings and Reviews. Many independent air purifier evaluating sources have published their assessments of air purifier companies and their products online. We consider several of these third-party reviews to be reputable and well-researched. However, professional reviewers often make recommendations that contradict one another. Rather than relying on a single source, U.S. News believes consumers benefit most when these opinions and recommendations are considered and analyzed collectively with an objective, consensus-based methodology.
  • Consumer Ratings and Reviews. U.S. News also reviewed published consumer ratings and reviews of air purifier providers. Sources with a sufficient number of quality consumer ratings and reviews were included in our scoring model.

Please note that not all professional and consumer rating sources met our criteria for objectivity. Therefore, some sources were excluded from our model.
(b) We standardized the inputs to create a common scale.

The third-party review source data were collected in a variety of forms, including ratings, recommendations, and accolades. Before including each third-party data point into our scoring equation, we had to standardize it so that it could be compared accurately with data points from other review sources. We used the scoring methodology described below to convert these systems to a comparable scale.

The 360 scoring process first converted each third-party rating into a common 0 to 5 scale. To balance the distribution of scores within each source’s scale, we used a standard deviation (or Z-Score) calculation to determine how each company’s score compared to the source’s mean score. We then used the Z-Score to create a standardized U.S. News score using the method outlined below:

  • Calculating the Z-Score: The Z-Score represents a data point’s relation to the mean measurement of the data set. The Z-Score is negative when the data point is below the mean and positive when it’s above the mean; a Z-Score of 0 means it’s equal to the mean. To determine the Z-Score for each third-party rating of a company, we calculated the mean of the ratings across all companies evaluated by that third-party source. We then subtracted the mean from the company’s rating and divided it by the standard deviation to produce the Z-Score.
  • Calculating the T-Score: We used a T-Score calculation to convert the Z-Score to a 0-100 scale by multiplying the Z-Score by 10. To ensure that the mean was equal across all data points, we added our desired scoring mean (between 0 and 10) to the T-Score to create an adjusted T-Score.
  • Calculating the common-scale rating: We divided the adjusted T-Score, which is on a 100-point scale, by 20 to convert the third-party rating to a common 0-5 point system.

(c) We calculated the 360 Overall Score based on a weighted-average model.
We assigned “source weights” to each source used in the consensus scoring model based on our assessment of how much the source is trusted and recognized by consumers and how much its published review process indicates that it is both comprehensive and editorially independent. The source weights are assigned on a 1-5 scale. Any source with an assigned weight less than two was excluded from the consensus scoring model.

Finally, we combined the converted third-party data points using a weighted average formula based on source weight. This formula calculated the consensus score for each product, which we call the 360 Overall Rating.
