15 Best Air Purifiers For Pets

Investing in a high-quality air purifier may be the simplest method to improve your home's quality of life rapidly.

Taking the time to research and select a right air purifier for your living area is doubly important for pet owners due to its capacity to properly eradicate pet-produced allergies.

At its best, an air purifier suitable for use with pets will be powerful enough to clean an entire room, quiet enough not to disturb you while in use, and fairly priced to allow you to furnish every room in your home.

BestForPets (bestforpets.org) has discovered that not every air purifier can live up to these expectations after rigorous testing and research-and to spare you the time and money of picking through any duds. 

This is a complete guide to the best air purifiers for pets and people who love them. 


Honeywell HPA300 True HEPA Air Purifier – Overall Winner

Honeywell’s HPA300 is a highly efficient true HEPA filter air purifier that comes with everything you need for clean air in rooms up to 465 square feet.

Its three air cleaning settings (including an ultra-powerful Turbo setting) allow you to dial in the ideal combination of noise level and purification, making it a versatile option suitable for any area in your home.

The HPA300 can circulate the whole volume of air in a room up to five times on its highest setting.

This Honeywell air purifier is quick and efficient, and it can easily keep up with pet hair and dander all year.

Replace the prefilter every three months and the main filter once a year, and you’ll have perfect air quality every day.

While all of these features would be enough to make the Honeywell a strong contender at any price, its low cost easily makes it our top option.

Overall, you won’t be able to find a better air purifier for the price.


  • The dimensions are 9.25 x 20 x 22.25 inches.
  • Covers up to 465 square feet of floor space.
  • 4 different filtering speed settings
  • Push-button controllers that are simple to use
  • It has an auto-off timer option.
  • The control panel dimmer allows it to be used in the bedroom while sleeping.
  • The filter change indication informs you when it is time to replace the filter.


  • The pre-filter is not washable and must be replaced every three months.


LEVOIT Core 300 Air Purifier – Excellent Buy

Unlike the other air purifiers on this list, which can clean the air in even the largest of living rooms, the LEVOIT Core 300 Air Purifier serves a distinct purpose.

It is available at a quarter of the cost of any other true HEPA filter purifier we evaluated as a tiny and ultra-efficient air purifier.

It covers up to 219 square feet of room space and is a low-cost equipment that may be the best air purifier for pets for the money.

We like the Core 300’s tiny frame and sturdy build, which measures 8.7 x 8.7 x 14.2 inches and weighs just under 9 pounds.

It’s lightweight and easy to move from room to room, making it an ideal addition to your bedroom or home office.

Even better, it’s Energy Star Certified, which means you’ll save money on your electricity bill.

In short, the LEVOIT Core 300 is a cost-effective and efficient air purifier that is excellent for treating a single room in your house.


  • Operating noise level of 24 decibels is extremely low.
  • The compact and space-saving design fits in any room.
  • The proprietary Vortexair design generates a strong airflow, enabling for coverage of up to 219 square feet.
  • Its abrasion-resistant inner structure and high-precision motor bearing make it one of the market’s longest-lasting purifiers.
  • Energy Star certified for energy efficiency


  • Filters have a lifespan of 6 to 8 months.


Premium Choice: Coway Airmega 400 Smart Air Purifier

The Coway Airmega 400 is supposed to filter the air for a staggering 1,560 square feet of room space, the most of any air purifier we tested.

It’s the only air purifier powerful enough to take care of your entire space in a single box for anyone with an open floor plan that includes a living room, kitchen, and dining room.

The Airmega 400 has 5 fan modes, the lowest of which is practically silent and the highest of which is a modest 43.2 dB.

The fan speed can be programmed to automatically adjust to the air quality of the room, as well as configured to run for 1, 2, 4, or 8 hours.

This huge air purifier is Energy Star certified, making it extremely efficient, and a 1-year manufacturer’s guarantee protects your significant initial investment.

Overall, the Coway Airmega is the most expensive air purifier on our list, but it is far from excessive due to its strong design and abundance of useful features.


  • Large room coverage – over 1500 square feet of purifying power
  • Permanent pre-filters are washable and reusable indefinitely.
  • The pollution sensor displays the current air quality in real time.
  • When operating at any of its five fan speeds, it is exceptionally quiet.
  • Smart adjustment mode adjusts to the air quality in the vicinity.
  • Electricity bills are reduced because to energy-efficient architecture.


  • It’s quite pricey.
  • Because of the bright LEDs, it is less ideal for usage in bedrooms.


Hathaspace True HEPA Air Purifier Smart

The Hathaspace True HEPA Air Purifier is a good middle-ground between our top recommendations because it is both tiny and capable of purifying up to 350 square feet of room space.

It’s just big enough for most living rooms while being much less expensive than whole-house ones like our top selection.

We particularly like the Hathaspace’s 5-stage filtration technology, which includes an Activated Carbon filter in addition to a HEPA filter and an ozone-free ionizer layer for optimal absorption.

This makes it one of the few purifiers in our tests that can remove scents from the air, making it an appealing alternative for multi-pet households that tend to gather pet odors more quickly.

When set to auto mode, the Hathaspace will only turn on when it detects a need for air purification.

While you will need to change and clean the filters on this more frequently than most air purifiers, this should not prevent you from taking advantage of a remarkably convenient unit at a low price.


  • A cold catalyst filter, activated carbon filter, antimicrobial coating, genuine HEPA filter, and optional ionizer are all part of the 5-stage filtration system.
  • The smart air quality sensor activates the system for purification only when it is required.
  • It includes a remote control for convenient use.
  • Sleep mode is whisper-quiet at 20 decibels.
  • A two-year warranty protects your investment.


  • For the price, coverage is quite limited.
  • Replacing several filters can be expensive.


Beach TrueAir Air Purifier Hamilton 04384

Hamilton Beach’s TrueAir Purifier is the smallest and least priced air purifier we evaluated, offering an impressively compact and low-cost solution for cleansing the air in a single small room.

With only 140 square feet of coverage, don’t expect it to cover an entire living room; however, if you’re looking for a low-cost option to try an air purifier in your bedroom or workplace, it might be worth a closer look.

The TrueAir efficiently removes odors and allergens from the limited area it can cover by combining a real HEPA filter with two carbon zeolite filters.

It’s nearly silent on its lowest setting and measures just 10.84 x 8.08 x 16.43 inches, making it ideal for apartment bedrooms.

The Hamilton Beach, as one of the few purifiers we examined with a permanent HEPA filter, is likely to be the most cost-effective option for cleaning the air in a small room over time.


  • Ultra-portable and ultra-compact
  • A low-cost method of testing an air purifier in your home or office.
  • A three-stage filtering system aids in the removal of smells and allergens.
  • There is no need to purchase replacement HEPA filters because the permanent filter may be vacuumed.


  • 140 square foot covering area is extremely limited.


True HEPA Filter Germ Guardian Air Purifier

The Germ Guardian Air Purifier is specially intended to battle the growth of germs and viruses in your house, and it has a final UV light filtration stage in addition to HEPA and carbon filters, making it one of the most comprehensive filtering systems we evaluated.

While its 167-square-foot room coverage restricts its total utility, the additional filtration steps make it a suitable companion for allergy sufferers’ beds.

The Germ Guardian’s drawbacks are its relatively loud operation and exorbitant price in comparison to its coverage area.

A 3-year guarantee, on the other hand, is better than any other purifier in our evaluation, and this, combined with its Energy Star Certified efficiency, earned the Germ Guardian our approval.


  • 5-stage purification is thorough and prevents odor buildup.
  • The final stage of UV light filtration kills bacteria and viruses.
  • Electrical efficiency is certified by Energy Star.
  • The impressive 3-year warranty protects your investment.


  • For the price, the coverage region is limited.
  • Frequent filter changes are required.


Ultimate Pet Filtration Air Purifier Winix HR900

The Winix HR900 Ultimate Pet Filtration Air Purifier is a worthy alternative to our top pick, covering a good 300 square feet of room space while providing 5-stage filtration complete with odor absorption.

However, given its somewhat expensive price range, we found ourselves wanting for broader coverage area to justify the substantial initial expenditure.

A washable odor control carbon filter is a fantastic design element that allows the Winix to collect pet scents without increasing maintenance costs with regular replacements.

When combined with a washable pre-filter, it makes the HR900 an affordable long-term solution for pet owners’ air purification.


  • The 5-stage filtration system absorbs and removes smells, allergens, and pet hair.
  • With a coverage area of 300 square feet, it is perfect for most living rooms or bedrooms.
  • Washable carbon filters and pre-filters save money over time.


  • On the pricey side
  • A greater service area would be more cost effective.


MYair Purifier BISSELL 2780A

The Bissell MYair Purifier, another contender for a small, compact air purifier, is only limited by its small room coverage area.

With a purifying capacity of roughly 100 square feet, it has the smallest coverage area of any purifier in our reviews.

While the Bissell’s utility is obviously limited by its small room size, the design overall is rather well-made.

A 3-layer filtration system aids in the reduction of odors and allergens, and the low operating noise level makes it suited for use in bedrooms and offices.

Overall, we can only suggest the MYair Purifier as a viable alternative to our best value pick, particularly for those seeking odor removal as part of their tiny purifier package.


  • A three-stage filtering system minimizes odors and allergens.
  • Transportable and portable
  • The operation is quiet.


  • Small room coverage area
  • Given the coverage, the price is difficult to justify.


Air Purifier Rabbit Air SPA-625A BioGS

At first sight, the Rabbit Air SPA-625A appears to be a solid competitor for an air purifier for pets, with certification for filtering a 625 square foot room and 4 stages of filtration and deodorization.

Indeed, the product’s silent operation, long-lasting filters, Energy Star certification, and 5-year warranty all witness to its high quality.

So, why is it ranked so low on our list? Unfortunately, the Rabbit Air is simply too pricey for us to endorse it wholeheartedly.

In comparison to our top recommendations, the SPA-625A provides too few additional benefits to justify a price nearly twice as high as our top pick.

It’s clearly efficient and sturdy, but until the price drops, it’s likely to be a niche selection due to its aesthetically beautiful appearance.


  • Superior filtration quality
  • Excellent coverage area


  • Far too costly
  • Doesn’t provide enough value to justify the price.
  • Filtration speeds are slow.


BreatheSmart Classic Air Purifier by Alen

The Alen BreatheSmart Classic Air Purifier, which is more expensive than even our Premium Choice option, is a strong and well-equipped air purifier that is simply way too pricey to justify its performance.

The BreatheSmart, despite its 1100 square feet of covering area, odor and allergen filtration layers, and ultra-quiet operation, cannot compete with its excessive price.

At nearly three times the price of our top pick, it lacks the utility to compete in this category.

Furthermore, the Alen comes with no manufacturer’s warranty. That is a deal breaker for us for a machine of this pricing.


  • A broad covering area
  • Filtration of odors and allergens that is effective


  • Far, far too costly
  • This product comes with no warranty.
  • Frequently replacing filters
  • The bulky shape makes it difficult to transfer from room to room.

Buyer's Guide: Choosing the Best Pet Air Purifier

It can be difficult to verify whether a given air purifier’s promises are verifiably real or simply salesmanship without going to the trouble of laboratory-grade testing.

To prevent wasting money on a subpar product, it’s a good idea to educate yourself about the ins and outs of air purifiers, which we address in the following sections.

What Benefits Can an Air Purifier Provide to You and Your Pets?

An air purifier is meant to do one thing incredibly well in order to create the greatest environment for you and your pets: catch and eliminate tiny particles from the air in your home.

A well-designed air purifier may collect nearly 100% of pet dander from the air, in addition to filtering out common allergens such as dust, mold, pollen, and smoke.

Combining an air purifier with a daily vacuuming program will swiftly eradicate the negative impacts of pet-related allergens for mild to moderate allergy sufferers.

Overall, air purifiers can be a low-cost investment in improving your and your pet’s quality of life, allowing you to enjoy your days more and sleep better at night.

What to Look for When Purchasing an Air Purifier

We reduced our comparison categories down to the following qualities after testing and studying dozens of air purifiers appropriate for pet-friendly homes:

Quiet operation may be the most significant distinction between a low-quality air purifier and a high-quality device. We search for purifiers that run quietly enough that you can sleep while they’re on, and we prefer models that don’t have extremely bright or aggressive lighting characteristics.

Effective filtration is the deciding factor in any pet air purifier. If it is not a HEPA (High-Efficiency Particulate Air) filter, it is not worth purchasing for your home. True HEPA filters are the most effective at absorbing and removing airborne particles, including pet dander.

Room Coverage Area should be proportionate to the size of the room in which you intend to use your air purifier – the larger the coverage area for the price, the better value you’re receiving for your money. If you have the cash for a larger purifier, it’s a wise investment to make; a high-coverage purifier in a small room will filter the air faster and more efficiently.

You can pick between all-day filtration and intermittent bursts, which are sometimes more energy efficient. Look for purifiers that have at least two fan speed options, high and low.

The final aspect that determines if a purifier is worth investing in is the longevity of both the equipment and the filters. More expensive air purifiers frequently come with longer warranties, making them the safest option for long-term use.

Air Purifier Types

There are five types of air purifiers on the market today, each with their own set of advantages and disadvantages.

These are distinguished by their filtering mechanisms and include:

HEPA filters must trap at least 99.97% of all particles larger than 0.3 microns, including allergens and pollutants including chemicals, bacteria, viruses, pet hair, mildew, and bacteria. They are the most effective trapping medium available today and our top recommendation for pet owners.

Because activated carbon filters can chemically react with certain airborne contaminants, they are a viable alternative to HEPA filters for people who are sensitive to odors or chemicals. They are not, however, as effective at absorbing dust and pet dander as a HEPA filter.

UV technology is frequently utilized as an add-on to particle filtration systems, where it gives an extra layer of protection by destroying germs and viruses. They are typically used in professional settings and can help decrease or eradicate airborne scents over time.

Negative ion purifiers use magnetic polarization to capture and trap airborne particles, but are less effective than the filters discussed above. We do not recommend using an ionic air purifier as the sole purifier in a home.

Ozone purifiers are a dangerous alternative for home air filtration and should be avoided; we discuss them here so you don’t get one for your home.

More information regarding the potential effects of ozone in enclosed places can be found on the Environmental Protection Agency’s website.

HEPA Filters and How They Work

HEPA filters function by physically capturing airborne molecules in their extremely fine mesh sieves, and were developed from a lengthy line of folded paper filters that may date back to World War I.

These filters can trap approximately 100% of all particles larger than 0.3 microns in diameter by combining paper filters with a layer of dense glass fiber. To put this in context, the diameter of a human hair is typically between 50 and 150 microns.

If you want to understand more about this type of filter, watch this video from How It’s Made on YouTube, which describes the full air filter manufacturing process:

How to Install and Maintain an Air Purifier

Once you’ve decided on an air purifier for your home, there are a few basic procedures to do to ensure optimal filtering performance. Take a look at the following:

Remove the plastic covering on the filter when your air purifier arrives. Many air purifiers come with the filter already installed but not yet unwrapped; using your new purifier in this manner will be useless at best and potentially harmful at worst.

Place your new purifier at least 18 inches away from any walls or furniture, preferably in the center of the room. This maximizes airflow and filtration efficiency.

Air purifiers operate best in the room in which they are placed, so consider purchasing multiples for a bigger space or moving it from room to room in your home on a regular basis.

If you want the best possible air quality, keep your doors and windows closed and your air purifier on the lowest setting 24 hours a day.

Set a reminder on your calendar to clean the prefilter once a month and to replace the filter at the manufacturer’s recommended interval (usually one year per filter).


In our opinion, the Honeywell HPA300 True HEPA Air Purifier‘s combination of silent operation, large room coverage, and low price puts it head and shoulders above the competition.

Only the Honeywell air purifier, which we tested for these evaluations, struck the sweet spot of giving approximately 500 square feet of air-purifying coverage at a fair price.

This is the air purifier to get if you want to improve the quality of life for you and your pets.

However, for smaller areas or on a tighter budget, the LEVOIT Core 300 Air Purifier is a more affordable alternative to our top selection.

It’s small, quiet, and ideal for improving the air quality in your bedroom or workplace rather than a huge living room or dining room.

Choose the LEVOIT if you need a space-saving air purifier to clean a specific room in your home.
