Through our in-depth review process, the first place of the best air purifier for pets is changed. We have to say goodbye to the previous Winix HR1000 – our last best air purifier for pets. And welcome the new Champion – the Winix HR900. Though not being the most expensive air purifier, the Winix HR900 is one of the best devices that come out of the Korean brand, with dual-filtration for all pet issues and a powerful fan. Seriously, there isn’t another air purifier out there with many features at such a low price as this.

The highlight of this Winix HR900 against all types of pest problems and pet allergies is as below. What made the Winix HR1000 the best air purifier for pets last year, once again is the unique selling point of this Winix HR900. The 5-stage air cleaning system, with the core, is a combination of a tier-one True HEPA filter and PlasmaWave technology, allows the Winix HR900 to remove and destroy 99.97% of any particles that your pets are shedding into the air. The particulate matter is down to 0.3 microns, meaning any pet hair and pet dander that trigger your pet allergies will disappear.

The True HEPA filter from Winix HR900 not only captures the tiniest pollutants, but it also lasts longer without cleaning thanks to the dual pre-filter – which covers the True HEPA filter and captures most of the particles like pet hair, fur, and even pet dander. This is also called the Ultimate Pet Pre-filter.

To guarantee that you will no longer live with pet allergies, the Winix HR900 features the unique PlasmaWave technology, that emits electrical discharge to create dual polarity ions (positive and negative) and disperses them into the air. As the ions attach to the surface of air pollutants, such as bacteria or viruses, they naturally remove hydrogen from the molecular structure of air pollutants, thus eliminating them and resulting in a cleaner, fresher air.

Finally, with the Coated Deodorization Activated Carbon filter, Winix HR900 can offer 97% protection against any types of pet odors, smoke and even Volatile Organic Compounds (VOCs). And the performance rating will greatly increase thanks to a more powerful fan of Winix HR900, with CADR of 200 Dust/ 220 Smoke/ 194 Pollen (cfm).

Smart Sensor is here, as is an exceptionally good sensor. With this sensor, you don’t need to control your air purifier anymore, as Winix HR900 automatically detects the indoor air quality, feedback to the users and adjusts the fan speed to deal with the volume of contaminants. So, just set it and forget it, you can play with your pets without worry anymore.


Do you prefer a budget device from a well-known brand? Levoit is the most popular air purifier brand at the moment, and their latest Levoit Core 300 could be the best budget air purifier for pet owners, for less than $100. For every pet problem of yours, this Levoit Core 300 can eliminate quickly. The Levoit Core 300 makes use of a certified True HEPA filter, which can be customized specially for all pet problems. Thanks to this advanced air filtration system, Levoit Core 300 can capture 99.97% down to 0.3 microns particles. For approximately 75% of cat, dander particles are 5 to 10 microns and 25% are 2.5 microns or smaller, this Levoit Core 300 will solve your pet allergies without any troubles. In addition, the Pet Allergy filter from Levoit Core 300 adds high-grade granular carbon, which is more effective to adsorb and chemically decompose pet allergies, odors, cooking smells. It is highly recommended for per lovers.

The fan power isn’t a downside for being a budget air purifier like the Blue Pure 411 because Levoit Core 300 has a capability of 215 square feet, with a massive CADR rating of 135 cfm. Moreover, we can use this air purifier while sleeping, thanks to its perfect quiet operation.

3) Germguardian AC5250PT – AMAZON BESTSELLER

It is not a surprise when you see a GermGuardian air purifier in any list of best air purifiers, especially in the list of best air purifiers for pets. For an affordable price, we highly recommend GermGuardian AC5250PT – one of the Amazon Bestsellers.

GermGuardian AC5250PT improves upon its predecessors with a new Pet Pure Treatment technology to optimize the performance of its True HEPA filter. The new air filter still can capture 99.97% of allergens as small as 0.3 microns such as household dust, pet dander, mold spores, and plant pollen, but will also resist the growth of bacteria on its surface. Such high-quality feature in a $100 air purifier is unbelievable.

The UV-C Light filter is the signature feature of all GermGuardian’s air purifiers, to destroy even the smallest bacteria and viruses in the air. With this powerful combination, you won’t need to live with your pet allergies anymore, all thanks to GermGuardian AC5250PT.

Only one downside, the Activated Carbon filter is attached to the pre-filter. By doing so, you need to replace the pre-filter quite regularly (about 7-8 months). That means you need to replace the whole internal air filtration system annually, and believe me, the cost is high.


Honeywell series has long been the best True HEPA air purifier with a powerful fan and that continues (and shines) with the excellent Honeywell HPA300. More than 25 years in this industry, there is no Honeywell air purifier that could reach the same success as the Honeywell 50250, except for the powerful Honeywell HPA300. Without any Smart features, the Honeywell HPA300 is still the top pick simply because of its reliable and wonderful performance.

Honeywell HPA300 has only a 2-stage air cleaning system, but the standout feature is its True HEPA filter. This air filter can capture an astonishing 99.97% of airborne particles at 0.3 microns, and even the 0.005 microns viruses. That’s why we called the Honeywell HPA300 True Allergen Remover. You will immediately feel the difference in air quality after running this unit in just 10 minutes.

One prominent feature from this Honeywell HPA300 is the unmatched fan power. For a $200 air purifier, Honeywell HPA300 has high CADR of 320 Dust/ 300 Smoke/ 300 Pollen (cfm). This CADR is higher than even the $600 Rabbit Air MinusA2 or $650 Honeywell HPA600B. We don’t imply the CADR rating to indicate the performance of one air purifier, but with such high CADR, Honeywell HPA300 will clean all your pet allergens really quickly.

But, just like the aforementioned GermGuardian AC5250PT, you need to replace the pre-filter because it is attached to the Activated Carbon filter. This will bump up the annual filter cost for the Honeywell HPA300, especially when you need to change the pre-filter once every 3 months.


For us, the Modify MA-40 is the best Modify Air’s HEPA air purifier for pets in 2020. It offers high-quality performance and impressive fan power but at a price that’s a bit easier to stomach than the Modify MA-112. As a brand making only the H13 True HEPA air purifiers, it is not so hard to understand why the Modify MA-40 is one of Amazon’s Choices today.

With the combination of the H13 True HEPA filter and the anions, the Modify MA-40 can effectively remove 99.97% pet dander allergies, pet hair, mold spores, dust mites, pollen, allergens, and other solid particles. Even the airborne impurities as small as 0.1 microns won’t escape this powerful True HEPA filter. Moreover, Modify Air added a seal around the filter to ensure the air does not by-pass the HEPA filter. So to say, you will only breathe the fresh air, without pet dander and pet hair.

Modify MA-40 has a substantial Activated Carbon with carbon pellets to even deal with the toxic odors, smoke, and formaldehyde. Pet odors will never be trouble anymore.

Just like any other high-end air purifiers, the Modify MA-40 makes use of an accurate Smart Sensor, to give you a visual sign of the indoor air quality in your room, as well as automatically adjust the fan speed depending on the air quality reading of the air pollutants.


Today, it is hard to miss the influence of Levoit LV-H132 if you are ready to buy an air purifier. The device itself is a phenomenon, with a sleek design and a beautifully low price. But it seems Levoit just uses the compact air purifier as a start for more premium devices. The Levoit LV-H134 is exactly the attempt this company makes to dominate the mid-range market, which we need more time to have the answer. However, for everyone’s pet issues, the Levoit LV-H134 is truly prominent.

The latest True HEPA filter from Levoit LV-H134 is more sturdy built, which can help neutralize 99.97% of as small as 0.3 microns allergens, including pet dander. To combat the pet odor, this air purifier contains lots of Activated Carbon inside the air filter.

With big size, the Levoit LV-H134 will impress with its high fan power, with CADR rating as high as 312 cfm in general. For the price, this air purifier can cover a large room of 710 square feet with ease. We have tested the performance of this Levoit LV-H134 against two cats and one dog in our lab, and of course, we never experience the pet odors or the common cat allergies from even the most sensitive people.

As for the Smart Sensor, this is one of the most accurate sensors we’ve ever seen. And don’t forget the convenient Sleep Mode, which keeps the air purifier operate at the lowest setting for your night time.


The AIRMEGA 400 muscles its way to the head of the best air purifiers for pets list with both impressive innovations and unexpected discounts for the price. AIRMEGA is the flagship lineup of Coway – the best air purifier manufacturer in Korea at the moment, and the AIRMEGA 400 is the truly high-end solution for any types of pest problems.

AIRMEGA 400 combines both True HEPA and Activated Carbon filters into one Max2 air filter. The performance is incredible, even without an ionizer like the famous Coway AP-1512HH, as the AIRMEGA 400 can remove up to 99.97% of any airborne particles down to 0.3 microns, including of pet dander, pet hair and more.

The carbon part in the Max2 filter is made of high-quality carbon, so it can reduce more than 99 percent of volatile organic compounds and reduces fumes such as NH3 and CH3CHO. You will get a 100% ozone-free air purifier with nearly perfect performance rating, and all for a discounted price.

Capping off an impressive 2019 for Rabbit Air, the Rabbit Air MinusA2 is once again the candidate of the list of best air purifiers for pets. This air purifier is a masterpiece that packs an inordinate amount of features into its sleek body. With such a top-notch air filtration system, the Rabbit Air MinusA2 is the luxury mid-range air purifier you can get to deal with your pet allergies and pet problems.

Rabbit Air MinusA2 runs with not 2 or 3 stages of air filtration, instead, you will be amazed by its 6-stage air cleaning system. First, any allergens need to pass through double the preliminary filtration, which makes sure to capture any types of pet hair, fur or feathers.

Next, our main compliment, is the Advanced BioGS HEPA filter, which is a certified True HEPA filter to capture 99.97% down to 0.3 microns allergens like pet dander, virus particles, pollen, mold, and fungi particles. But due to the Advanced BioGS technology, this HEPA filter can last for at least 2 years without replacing, efficiently reduces the annual filter cost. Also, with the combination of an ionizer, the performance of this Rabbit Air MinusA2 is enhanced further.

If you have extreme allergies with your pets, or you can’t stand the pet odors anymore, you can choose between the Pet Allergy or Odor Remover for the Customized Filter of this Rabbit Air MinusA2. These air filters are specially engineered and designed to improve the removal against some specific irritants.

Don’t forget that Rabbit Air MinusA2 is currently the best air purifier in 2020, it will feature the high-end features like Smart Sensor or Smart Wi-Fi connectivity. We guess that you don’t need a reason to know why you need these modern features, right?

Since 1990, Austin Air has been the most well-known brand in the American air purifier market. They are featured in medical and health newsletters including Dr. Whitaker’s Health & Healing, and also selected by the U.S government to help protect the residents of Anniston, Alabama during the elimination of chemical weapons. With such a strong foundation, there is no doubt the Austin Air Pet Machine is the ultimate solution for all your pest troubles.

This Austin Air Pet Machine is designed specifically for customers with pets looking to remove unwanted odors, pet dander and animal allergens from the home.

If you are a pet owner who (or your family members) suffers from a pet allergy, since this problem is really serious, you should purchase for the best air purifiers available in the market.

We highly recommend that you read these best air purifiers for allergies in 2020, we have listed all the top-rated air purifiers to combat with the allergy pollutant particles.

Important Note: The best air purifier to help remove the tiniest particles of pet dander need to have a True HEPA filter.


The problem with pet hair, fur and feather are much easier. Those visible things are too large to be captured by just an average air purifier, so you won’t need to spend lots of money for a True HEPA filter air purifier.

The best air purifier for pet hair only will have a “HEPA-type filter”, or “HEPA-like filter”.

For the high-end air purifiers, you should look for an air purifier that has washable pre-filter. Because these filters will almost last permanently, these air purifiers are the most reasonable things to buy.


The only filter can help you adsorb odors (as well as other chemicals and smoke) is Activated Carbon filter.

Activated Carbon air filter (many brands just call Charcoal air filter) uses a special form of activated carbon that consists of millions of tiny adsorbent pores, to adsorb and neutralize volatile chemicals on a molecular basis (for example harmful gases, odor, VOCs and some chemicals).
