Fortunately, air purifiers can help improve the air quality in your home and eliminate the toxins that your furry family members may be unable to prevent. Our best air purifier reviews help you find the best fit for your needs.

Article Overview

Best Air Purifiers For Pets

Ahhhhh, now you can stop holding your breath as it’s the moment you’ve been waiting for: our recommendations for the best air purifier for allergies and pets.

Note: While conducting our research for this article, we noticed some users complaining about the release of cool air from air purifiers. To clarify, this is totally normal, and it’s natural for there to be a slight breeze.

Pet Odors: GermGuardian AC4825 Review

GermGuardian AC4825 3-in-1 Air Cleaning SystemView on Amazon

The GermGuardian AC4825 is a high-performing air purifier for dog smells at a reasonable price. This air purifier claims to capture 99.97% of dust and allergens (as small as 0.3 microns), including pet dander, mold spores, and plant pollens.

It has UV-C light technology, which kills bacteria, viruses (including rhinovirus, e.coli, and streptococcus), germs, and mold spores in the air. The charcoal filter reduces cooking, smoking, and pet odors, and the HEPA air filtration system helps reduce exposure to asthma triggers. For all of these reasons, we think it’s the best air purifier for pet odors.

Our Personal Experience

We bought this air filter to minimize dog smells in our basement since that is where their dog crates are. It has exceeded expectations by getting rid of the doggy smell quickly, reducing the amount of time we have to run it.

As a bonus, it also reduces fire pit and cigar odors that waft in through the basement door and damp smells when it rains. It’s so quiet that we sometimes forget to turn it off, but I am not complaining about that! It’s been a great air purifier for pet smells. – Michelle S., Canine Journal

Pros

Cons

  • CADR rating: 100+
  • HEPA filter lasts for 6-8 months
  • Earned the Energy Star by the U.S. EPA
  • Certified energy efficient
  • Is great at removing smelly odors
  • Customers state allergies are more manageable indoors
  • Small design
  • Quiet on low and medium
  • Easy to set up
  • 3-year warranty
  • Small light can be annoying to some if they keep it running during the night; however, it’s easy to cover
  • A small number of customers say there’s a plastic smell when you first use it, but it goes away after a day or two of use

Dog Hair: Filtrete Air Purifier Review

Filtrete Air PurifierView on Amazon

Like other air purifiers in this article, Filtrete’s air purifier claims to capture 99.97% of airborne particles (as small as 0.3 microns), including dust, lint, dust mite debris, mold spores, pollen, pet dander, smoke, smog, bacteria, viruses, exhaust particles, and ultrafine particles. This air purifier can help clean air in rooms up to 250 square feet.

It has a change filter indicator to help you know when the filter has reached the end of its life. The top has a soft-touch display to adjust the fan speed, set a timer, dim the control panel lights, and reset the filter change indicator. We think this is the best air purifier for dog hair because it helps eliminate the smell and debris that comes with a shedding dog.

Our Personal Experience

I was sent a similar smart Filtrete air purifier (a smart air purifier and has a few advanced features) to test out in exchange for an unbiased review. I noticed our bedroom had a fairly strong pet odor in it, so I thought testing the air purifier in there would help me notice the most changes.

The air quality in our bedroom was absolutely terrible, I’m embarrassed to even share the numbers with you. When I set up the air purifier, the bedroom air quality was in the 120-range, which is deemed “poor.”

When I had the humidifier running in our bedroom, it worsened the air quality tremendously. This can happen depending on the type of water you use, how clean your humidifier is, how old the filter is, and more. Without the humidifier running, the air quality numbers were much lower in our bedroom. On average, our air quality is now less than five, which is deemed “good.”

This version of the Filtrete air purifier integrates with an app to adjust the fan speed, set a timer, see the filter life, learn more about pollutants, and more from my phone. I’ve been pleased with it and think it’s a great contender for the best air purifier for pet dander.

Since using the Filtrete air purifier, I’ve noticed the amount of dust, pet dander, and dog smell has decreased dramatically in our bedroom. We’re now considering purchasing a whole-home air purifier or additional units to be in other areas of concern in our home. – Kimberly A., Canine Journal

Large Spaces: Coway AP-1512HH Mighty Review

Coway AP-1512HH Mighty Air PurifierView on Amazon

This advanced air purifier uses a four-stage filtration system (pre-filter, deodorization filter, true HEPA filter, and vital ion) that captures up to 99.97% of particles (0.3 microns) in the air. It’s amazingly effective in reducing odor, pollen, pollutants, and many other allergens. We’ve read many customer reviews stating it’s the best air purifier for allergies and pets.

Its real-time pollution sensor lets you know how clean or dirty your indoor air is all day long. You can set the timer to turn off after one, four, or eight hours. And to save energy, this purifier will automatically stop the fan and go into Eco mode when no pollution is detected for 30 minutes.

This Coway purifier is designed to accommodate room sizes up to 361 square feet and is ideal for apartments, a great room, and other mid-sized spaces. Many users, however, report excellent performance in much larger spaces, which is why it’s the best large room air purifier for pets.

Pros

Cons

  • CADR ratings: 246 dust, 240 pollen, and 233 smoke
  • 4-stage filtration system
  • HEPA filter lasts for a year and odor filter for 6 months
  • Energy Star certified
  • Pollution sensor communicates indoor air quality in real-time
  • Filter lifetime indicator for pre-filter and HEPA filter
  • Quiet on low and medium
  • Attractive design and compact size
  • 3-year warranty
  • Set up instructions can be confusing
  • Some users say the fan is too noisy on high setting

Bedrooms: Levoit Core P350 Review

LEVOIT Air PurifierView on Amazon

The Levoit Core P350 air purifier has a Pet Lock that prevents the change of settings by pets or children. It can cover up to 219 square feet and has a three-stage filtration system (fine preliminary filter, true HEPA filter, and activated carbon filter) that captures up to 99.97% of particles (0.3 microns) in the air.

It’s effective in absorbing pet odors and decomposing them to eliminate second-hand pollution, which is why we think it’s a great air purifier for pet urine odor. You can set a timer for 2, 4, 8, or 12 hours.

This Levoit air purifier is smaller than others and runs quietly in the background so it’s a good option for your bedroom. It’s also a great air purifier for pet hair and dander and can help eliminate odors.

Pros

Cons

  • CADR rating: 240
  • HEPA filter lasts 6-8 months
  • 3-stage filtration system
  • Quiet
  • Easy to setup
  • Attractive design and compact size
  • 1-year warranty
  • Not Energy Star certified

What Are My Other Options For Air Purifiers?

Below are more air purifiers we reviewed that may be great fits for your home.

Dyson Pure Cool Link Review

View on Amazon

If you want a sleek and modern air purifier for dust and pet hair, look no further. The Dyson Pure Cool Link Air Purifier claims to remove 99.97% of allergens and pollutants as small as 0.3 microns.

Dyson has an app that includes information about the filter’s life, acts as a remote control, and lets you schedule when the purifier is on and off. It also has a night mode, which is quieter and dims the display.

The main reason this didn’t make our top picks for the best air purifier for pet hair is because of its high price point (without the technological advances you’ll find in the Molekule). You can get other HEPA air purifiers for much less, and they do just as good of a job as this Dyson does. Unless you want an air purifier with an app, we recommend looking at our top picks.

Pros

Cons

  • 360° air intake
  • Night mode
  • Can sync with your smartphone via app (iOS | Android)
  • Works with Amazon Alexa
  • Filter is replaced every 12 months
  • HEPA filter
  • 2-year warranty
  • Expensive
  • Since it’s more technical with the app, it can be tricky getting it set up at first
  • Issues with the app in the past

Holmes Review

Holmes HAP242-NUCView on Amazon

If you’re looking for a less expensive option to use in a 10′ x 11′ room, then the Holmes HAP242-NUC air purifier is a great choice. It claims to remove up to 99% of airborne particles as small as 2 microns. You can place the purifier vertically or horizontally on a desk, table, or other surfaces.

As stated, it works best for smaller rooms, approximately 110 square feet, so using this in an office or bedroom is ideal. This Holmes air purifier has a carbon filter which helps remove up to 44% of odors from the air.

Pros

Cons

  • CADR rating: 70
  • Filter lifespan varies based on the filter you buy
  • Filter change indicator
  • Small design
  • Quiet on low, medium, and high modes
  • Great value
  • Only collects particles down to 2 microns
  • Not stylish
  • Some customers complain of a chemical smell
  • Not the best air purifier for smoke
  • HEPA type filter is not a true HEPA filter

Honeywell 50250-S Review

Honeywell is a household name of security equipment, HVAC equipment, doorbells, and air quality equipment, including air purifiers. This Honeywell model’s glass fiber HEPA filter collects up to 99.97% of particles as small as 0.3 microns.

The system will notify you when you need to change or clean the filter. The pre-filter, which is carbon activated, captures larger particles and reduces odors and should be replaced every three months. However, if you vacuum the pre-filter, it can be extended to three to five years.

Pros

Cons

  • Filter can last 3-5 years
  • CADR rated 250 for smoke, dust, and pollen
  • AHAM Certified for rooms up to 390 sq ft
  • Filter change indicator
  • 360° air intake
  • Customers state allergies are more manageable indoor with this

Molekule Review

Molekule air purifierVisit Website

Is the Molekule the next-gen of air purifiers? That’s what they claim — and consumer feedback seems to agree that this new technology’s ability to clean the air is more effective than traditional HEPA-filtered purifiers. Molekule’s major selling point is PECO, an innovative nanotechnology that utilizes free radicals to oxidize pollutants and kill airborne viruses and airborne chemicals (called VOCs). They say that this technology can destroy pollutants 1,000 times smaller than traditional HEPA filters.

The only major downside we see for this product is its high price tag, which will turn away some consumers. They do, however, offer a 60-day money-back guarantee.

Pros

Cons

  • Very effective against mold and many allergens
  • Innovative technology has been third-party tested (and they publish test results)
  • Can choose room sizes (<200 sq ft, 200-400 sq ft & >400 sq ft)
  • Three operating modes: silent, boost, and auto
  • Glowing customer reviews about its performance
  • 60-day money-back guarantee
  • 1-year warranty
  • Very expensive
  • Replacement PECO filters are expensive (but you get your first year free)
  • Some users had problems with the smartphone app being buggy

Price

Molekule gives you one year of free filters and offers a 60-day money-back guarantee.

  • $799 (they also offer financing through affirm)
  • $129 subscription (optional) for a 1-year supply of PECO filters (change every 6 months) and pre-filters (change every 3 months)

Best Air Filters For Pets

Filtrete AC Furnace Air FilterEach of the air purifiers above takes its own specific filter. However, there are filters in your home’s furnace that need to be changed regularly. Depending on the type of air filter you get, you may need to change it every one to three months. However, if you suffer from allergies or have multiple pets, you may want to change your filters more often.

We recommend these Filtrete Odor Reduction pet dander air filters for furnaces for the best air filter for pet hair. These air filters can last up to three months and remove strong odors from the air, including smells from pets, cooking, mildew, and smoke. For the best air filter for homes with pets, consider Filtrete’s Odor Reduction.

Whole-Home Air Purifier Systems

If you don’t want to have an air purifier in every room, you can install a whole-home air purifier solution. These air purifiers can be in the thousand dollar range, so they aren’t as affordable as the air purifiers we reviewed for this article.

It’s an investment, for sure, but if you want a house full of clean air, a whole-home solution may be best for you.

What Are Air Purifiers?

Generally speaking, all air purifiers have an intake where the air is taken into the system to be filtered and another spot where it’s released after filtration.

By using an air purifier, the air in your home will smell and feel squeaky clean. You’ll notice your ability to breathe easier and may even find that you don’t need allergy medication as often.

Can Air Purifiers Prevent Illness, Like COVID-19?

Air purifiers won’t necessarily prevent you from getting coronavirus, but they can improve the air quality in your home to help someone suffering from COVID-19. Additionally, running an air purifier could help protect other family members or caregivers.

Understanding how COVID-19 spreads continues to evolve, but the general consensus is that it travels via viral droplets transmitted from the body. Air purifiers can help reduce airborne germs that cause the flu and common cold. So this device may reduce some COVID-19 airborne pathogens as well, but experts haven’t verified it.

Air Purifier Terminology & Technology

Cat sitting next to air purifier (caption: Best Air Purifier For Pets)Before we get into our best picks, we wanted to explain a little more of the technical side of how air purifiers work and what to look for when picking out the right one for you.

What Are HEPA Filters?

High-efficiency particulate air filters (aka HEPA filters) force air through a mesh screen and collect harmful particles like pet dander, mold spores, pollen, and dust mites. We’ve noted in our reviews which air purifiers use HEPA filters

Air Purifier Certifications

We discuss three certifications in this article: Clean Air Delivery Rate (CADR), Energy Star, and the Association of Home Appliance Manufacturers (AHAM).

  1. CADR is a measurement of how fast an air purifier delivers filtered air. The higher the CADR, the better.
  2. The U.S. Environmental Protection Agency (EPA) gives products the Energy Star rating when they meet energy-efficient guidelines.
  3. AHAM is an organization that inspects the performance of household appliances.

Note: Not all of the products listed below will have all three of these ratings. We provide information about these certifications for the products we could find.

What Is A Micron?

You’ll hear us refer to microns in this article and the size of microns an air purifier can handle. A micron is equal to one-millionth of a meter (in other words, it’s super small).

Here are some common particles in our air and their size in microns to give you some perspective.

  • Human hair: 80-100 microns
  • Pollen: 30 microns
  • Mold spores: 10-30 microns
  • Household dust: 10 microns
  • Pet dander: 5 microns
  • Smoke: 1 micron

If you want your air purifier to get rid of smoke, you’ll need one that can filter particles as small as one micron. If you want an air purifier to help with pet odor and dander, you’ll need one that can handle particles as small as five microns.

Our experts have reviewed some of the best vacuums for pet hair and share our findings with you.
