12 Best Air Purifier for Pets of 2022-Review & Buying Guide

85 million US homes have a pet, but about three in ten Americans suffer from pet allergies. They can have horrible symptoms and aggravate respiratory illnesses like asthma. But choosing the best air purifier for pets can help.

So, let’s find out more about these devices and how to pick a good one for your home.

How We Evaluated Air Purifiers for Pets

There’s a lot that goes into researching the finest. Here are the crucial aspects we considered.

Product Size

If you need a device in multiple rooms throughout the day, you can’t have something big and bulky. The average weight of the devices on our list is about seven pounds, but we have an extensive range from 0.5–21 lbs. 

Speed and Levels of Fan Speed

That’s how quickly the product will work through the air. Most purifiers have three-speed settings. But some go up to ten. The higher the fan speed, the quicker the air filters are. We checked whether the different fan speeds can filter and circulate the air sufficiently through the indicated space. 

Noise

An air purifier for pet owners shouldn’t make a racket while you work, sleep, or watch TV. But the sounds will get louder as the speed increases. We selected products with a good range between 18–52 dB, depending on the fan speed. Still, some devices include ultra-quiet modes for when you’re sleeping.

Air Quality Indicator

It’s the most crucial function of these devices because it will tell you how clean the air is and if it’s optimal. Most devices display the air quality through an app or on the device itself using different colors. You’ll be alerted in the same way when it’s time to replace the filters.

Medical-grade HEPA and/or Certified by Asthma & Allergy Friendly

Reviews on air purifiers show these devices are nothing without a certification proving they can clean the air — the more certifications, the better. All the devices on this list use HEPA filters, and some have an Energy Star certification, too.

Manufacturer Reputation 

We don’t trust the manufacturer’s description blindly. We looked closely at reviews for air purifiers for allergies and pets as those give the most honest product feedback. You can rest assured that you’ll find well-researched information below. 

Warranty

Purifier warranties primarily cover technical and physical defects of the product. Most devices on our list have a one-year warranty, but some go as high as five. 

LEVOIT Air Purifier for Home Large Room

For a device that can clean 403 square feet every 12 minutes, it’s surprising that it only weighs about six pounds, making it a top air purifier for pets. The dimensions are slightly bigger (10.79 x 10.79 x 20.47 inches), but it has a lot of work to do — getting rid of mold, pet dander, and pollen.

The air purifier is incredibly quiet, reaching only 24 dB on the lowest setting. Plus, the rubber on the bottom prevents vibrations. It’s one of our top choices for a quiet air purifier. 

The laser dust sensor is super helpful as the device monitors the particles and switches to the correct setting. Three rings with colored lights show you whether the air is good or bad.

But that’s not all. The device links to the app via Wi-Fi, giving you detailed and up-to-date information. Also, you can control the purifier through voice activation with Alexa or Google Assistant. 

The HEPA filters have a three-stage filtration that traps 99.97% of particles and neutralizes odors. What’s more, the core is CARB and FCC-certified. And the device has a CADR rating of 260. It’s one of the top choices for pets and dust. 

The purifier comes with a one-year warranty for any defects. You can purchase replacement filters when indicated by the device.

Buyer’s Guide

There’s a lot to consider when you’re in the market for an air purifier. Here’s what you should know.

What To Look For in a Pet Air Filter

Here’s what you should consider when you’re in the market for an air purifier. 

Coverage: It depends on how much air you need to be filtered and how quickly. If you’re looking for a one-room device, small square footage will be fine. But if you need a device to clean multiple rooms, you have two options — a portable machine to move around or a device for large spaces. 

Filter: Most devices on this list have replaceable filters. So once they’re full, you simply buy a new one and change it on your device. You can wash and reuse permanent filters, but finding an air purifier with a washable filter is no easy task. Permanent filters usually capture particles up to two microns, whereas replaceable filters can capture much smaller particles. 

Number of Pets: It depends on the breed, but overall, one pup doesn’t spread much dander. But having multiple dogs is another story. If that’s your case, you want to look for a device that can catch particles about 0.03 microns (HEPA).

Allergic Family Members: If someone in your home shows symptoms, you want to be on the lookout for an air purifier for pet allergies. These devices can genuinely make a difference, not only for pet dander but for pollen and dust, too.

Types of Particles: Viruses, toxins, smoke, and bacteria are all on the 0.01-micron level. Everything else, including dust, pet dander, and pollen, is 0.03 and above. The finest air purifier will capture particles of all sizes. 

Extra features: Some devices include a timer, LED indicators, odor or temperature control, and app compatibility, so pick the one that suits your needs.

Portable or permanent: The permanent device is fixed to your home, usually part of the HVAC system. But they can be expensive when it comes to the utility bill. Permanent devices circulate throughout your home and you don’t have to move them around or plug them in. In contrast, you can move the portable purifier around the house. 

Plug-in or battery: Plug-in devices can get frustrating if you constantly move and plug them in different areas. But battery-run purifiers need time to charge, so you can’t have them running for an extended period.

What Is a Pet Air Purifier and How Does It Work?

An air purifier helps clean the air of pet dander. The device takes the dirt in the air, filters it, and releases clean, dander-free air. 

The filters trap the allergens and don’t let them back into your space. That’s why cleaning the filters or replacing them is crucial. A full filter won’t work correctly and could give you even worse air, so learn how to check if your filter needs replacing.

Filter Types

Here’s what you should know about the difference between the types of a pet air filter.

HEPA filter: This stands for High-Efficiency Particulate Air filter, meaning it can remove airborne pollutants as small as 0.03 microns that you can’t see with the naked eye. It’s an industry standard for air purifiers. 

Activated carbon filters: They’re usually an addition to HEPA as a second or third line of filtration and are particularly good at removing odors. If you’re dealing with the latter, there’s also a range of pet odor eliminator products you can try, too.

UV filters: Ultraviolet light kills germs and bacteria. A device with a UV filter not only traps pollutants and fibers but will kill off any toxic particles. If you’re looking at an air purifier with no filter, this is a must.

Ozone: Some of you might recognize the smell that comes up when lightning occurs. Many people enjoy it, so some purifiers emit the scent. But it’s been recently discouraged as it can worsen respiratory illness. 

What Type of Air Purifier Is Best for Reducing Pet Dander?

The essential part is the HEPA filter, as it captures all particles — from small to large. That’s why there are different types of devices and an air purifier for cat allergies.

Pet dander is within the microscopic range. It affects you even if you don’t see it, especially if you have allergies. 

What Are CADR Ratings and MERV?

CADR stands for Clean Air Delivery Rate. It’s a term started by the Association of Home Appliance Manufacturers to give a numerical value on how many particles are removed from the air. 

So a higher CADR rating means that an air purifier can remove particles quicker, depending on the room size. Basically, the higher the fan speed, the higher the CADR rating. The highest CADR rating is 450.

Minimum Efficiency Reporting Values (MERV) is the particle size a filter can capture. It’s measured between 0.3 – 10 microns.

Like the CADR, the higher the MERV, the better the purifier is at catching a wide range of particle sizes. 

Benefits of a Pet Air Purifier  

Here are some of the reasons you might benefit from an air purifier.

Allergies and asthma: These two usually go hand in hand. If you have an allergy that affects your respiratory system like pet dander, dust, or pollen, that can aggravate asthma symptoms. An air purifier will clear the air, decreasing these allergens. Also, it’s not just us who suffer. Our four-legged besties can also have allergies. But most of them are from food, so if that’s your case, make sure your pet gets top-quality dog food for allergies. 

Pet and other odors: If you want to eliminate odors, look for an air purifier for indoor pets. Pets come with smells, and that’s part of the package. But that’s mostly when you have a small pup running around, so it won’t last forever. Still, other smells like those from cooking or a blocked drain can be horrible. And air purifiers, particularly those with a charcoal filter, can help a lot.

Pet hair and dander: Three in ten Americans are allergic to dogs and cats. A running nose, itchy skin, and tight chest aren’t fun, so an air purifier can help.

Less cleaning: Since air purifiers can grab bigger particles, there will be less dust and dander to clean up. However, even if you find the best air purifier for indoor pets, you’ll still need to sweep up from time to time. 

What Is Pet Dander?

Like us, animals shed skin and fur, which can be so microscopic that you can’t see it. When you have a pet allergy, you aren’t allergic to the fur, but rather to a compound on animals’ skin. So sweeping up the hair can help but won’t fix the problem. 

Cats are much more prone to causing allergic reactions in humans — about double the rate of a pup. Surprisingly, dogs and cats can be allergic to each other, as well as other air pollutants. A dog allergy testing kit can help you find out if your pup has an allergy.

Other Effective Solutions for Pet Dander

Aside from getting an air purifier, there’s a lot more you can do to reduce pet dander:

Air quality test kit: If you get an air purifier without an indicator, this device will be your best friend for clean and breathable air. The kit will show you the air quality. We recommend this accurate air quality monitor for indoors on Amazon.

Bathe your pup often: It will help keep your puppy’s fur in the best condition while also removing any loose fur that can make its way into the air and on your floor. You can wash your dog once a month if it has no underlying health conditions. 

Clean frequently: Even the greatest air purifier won’t get everything, so keep the broom, vacuum, and mop handy. Don’t let dirt sit for extended periods. Wash the floors and surfaces at least once a week.

Use a progressive vacuum with a HEPA filter: There’s no point vacuuming unless you use the correct filter. Otherwise, it could just move the pollutants and dust around. We recommend the Kenmore Elite 21814 on Amazon, which uses a HEPA filter and has attachments that reach all home areas. 

Air purifying pet-friendly plants: An entirely all-natural way to remove toxins and CO2 from the air. Also, these clean air houseplants on Amazon are super easy to care for. 

Limit your dog’s activity area: Pet gates and playpens are excellent options for keeping your pup in a limited space within the house. We recommend the PETMAKER Freestanding Pet Gate on Amazon. 

Final Thoughts on the First- Rated Air Purifier for Pet Dander

Three in ten Americans are allergic to pets. This can cause symptoms like difficulty breathing, itchy skin, and watering eyes. What’s more, asthma and respiratory issues can get worse.

To help with this, air purifiers remove pet dander, dust, smoke, and even germs and toxins.

The LEVOIT Core 400S is a fantastic choice for getting rid of these allergens. It monitors real-time air quality and adjusts accordingly. 

FAQ

Do air purifiers remove pet odor?

Purifiers with carbon or charcoal filters work wonders when it comes to ridding your home of pet odor. In contrast, a standard air purifier with a HEPA filter won’t do much for the smell, but it can remove harmful bacteria related to the smell and larger particles. 

Where to keep your air purifier?

Generally, placing it by a window or doorway will be your best bet. Since air gravitates towards these areas, it’s easier for the purifier to filter out the particles. Ultimately, it depends on the type of air purifier you get, but this is the rule for portable devices. 

How do you care for an air purifier?

To keep your purifier in good condition, replace the filter every six months, clean the device, and ensure you follow all care instructions that come with the device. Remember, even the absolute best air purifier for pets won’t clean itself.
