The Best Air Purifiers For Pets Let You Breathe Easier Around Furry Friends

While our furry family members are important and pet owners would never want to give them up, they do present some challenges with regard to indoor air quality. Pet fur and dander can aggravate breathing problems, especially for people who have allergies or are prone to asthma, Fortunately, there are ways to alleviate the symptoms brought on by having animals in the house and one of the main things you can do is use an air purifier for pets.

Pet allergies

Contrary to popular belief, it’s actually the microscopic bits of skin that pets shed – called dander – that are more likely to cause an allergy than the actual fur, says the American Lung Association (ALA). Allergies can also be caused by pet saliva or urine. Pet allergies are actually a big problem with Medicinenet citing that up to 20 percent of the North American population is affected by pets.

The ALA says that 27 percent of US households have cats and 32 percent have dogs, but that “roughly twice as many people report allergies to cats when compared to dogs.”  Cat lovers might want to make note that research has shown that male cats produce less allergen than female cats, although they don’t know why. The ALA notes that because dander is the main allergy trigger, short-haired or hairless animals are just as allergenic as all the rest. “There is no such thing as a non-allergenic dog or cat.” Research has also found dog and cat allergens in homes where pets are not even present. And, lest you think it’s just cats and dogs at fault, people can develop allergies to almost any kind of animal from horses and birds to rabbits, hamsters and other rodents.

Keeping Your Environment Clean

While using an air purifier for pets in the house is one step you can take to improve indoor air quality, there are other things you should do as well. Physically removing dander and fur on a regular basis is key, and this means sweeping and vacuuming frequently. Dander easily sticks to carpets, upholstery, bedding and clothing so wood floors are generally a better option if you have pets. Regardless, you will want to have a vacuum cleaner that includes a True HEPA filter to minimize the volume of allergens that are re-released into the air from the vacuuming process.

Controlling where pets go is another way to keep the environment cleaner. Keeping them out of the bedroom and off of upholstered furniture can lessen the amount of fur and dander that is in the environment.  Lastly, allergy experts recommend bathing you pet, however, if you have cats, we say good luck with that!

What features should an air purifier for pets have?

For the best results, any air purifier you select should have a True HEPA filter. These filters are certified that remove 99.97% of allergens down to 0.3 microns. This will filter out the most common allergens especially pet dander,  no matter the specific animal(s) that you have.

If you don’t have allergies and just have a pet hair problem, some sources suggest that you can get away with using a “HEPA type” filter that removes particles from two to four microns in size. While this can save you money in the short-term, it might not in the long term if you develop allergies and need a purifier to address them.  People can develop allergies at any age, even having had pets in the home for years without issue. WebMD says that adult-onset allergies are quite common. “’You’re fine, you’re fine, you’re fine … until you’re not.’ Nobody knows why.”

What about pet odors?

If pet odors are a concern, a True HEPA filter alone won’t help with that aspect of indoor air. For removing the smells associated with pets a purifier must include an Activated Carbon filter, which will absorb them. Some purifiers offer these as part of a multi-step filtration system, which also frequently includes a pre-filter, which pulls out the largest particles before they reach the HEPA filter. This makes the HEP filter more efficient and longer-lasting.

Choosing the Best Air Purifier for Pets

Where will you place the purifier?  Assuming that the model has a true HEPA filter and an activated carbon filter if you want to control odors, you need to consider the room where you want to use the purifier. It’s important to choose one that is designed for the specific size of the room – large or small.  Many models have a certified CADR — clean air delivery rate  — for general or specific indoor air pollutants, says Healthline. The CADR indicates how many particles and square feet the purifier can handle. According to Good Housekeeping, you want a general CADR of at least 300, and anything above 350 is excellent.

Look for certification. Specifically, you want the AHAM (Association of Home Appliance Manufacturers) Verified mark. This voluntary certification covers the safety and performance of many small home appliances, such as air purifiers. The AHAM certification usually means the product provides a CADR rating and size guidelines.

Prices vary widely on purifiers, so consider your budget, especially if you will want to have multiple units in your home. The cost to run them is typically not major, however depending on the model, replacement filters – which are absolutely necessary – can be costly.

Purifier for Pets FAQ

What is a HEPA Filter?

HEPA stands for high-efficiency particulate air and it uses a fine glass mesh to trap harmful particles. True HEPA filters remove at least 99.97% of particles as small as 0.3 micron in diameter in a lab setting and this is what you want from one of the best air purifiers for allergies. This covers most common indoor air allergens such as dust, dander, pollen and mold, says WebMD. Beware of the terms “HEPA-like” or “HEPA-type,” when describing a filter because these do not have any specific standards backing up their effectiveness.

What certifications s should a purifier have?

Specifically, you want the AHAM (Association of Home Appliance Manufacturers) Verified mark. This voluntary certification covers the safety and performance of many small home appliances, such as air purifiers. The AHAM certification usually means the product provides a CADR rating and size guidelines.

What is a CADR rating?

CADR, is the acronym that stands for Clean Air Delivery Rate. This is how the function of home air purifiers is measured. The CADR rating identifies the volume of air that is cleaned and is expressed in cubic feet per minute (CFM). The rating is used to measure effectiveness with three different kinds of air pollutant particles: smoke, pollen and dust, each of which gets its own score.

What does CARB Compliant mean?

CARB stands for the California Air Resource Board, which aims to achieve and maintain healthy air quality. protect the public from exposure to toxic air contaminants and provide innovative approaches for complying with air pollution rules and regulations. In 2008, CARB enacted regulations on indoor air-cleaning devices to limit ozone emissions.  The means that to be sold in or shipped to California, an air purifier has to comply with CARB regulations.

What other technologies do air purifiers use?

Various air purifiers offer other technologies, such as a UV light, which inactivates microbes but does not remove them from the air. Ionizers are another option, and these create negative ions that help draw particles from the and into the filter. The caution with ionizers is that many of them create ozone, which creates harmful effects of its own. Vice magazine notes that “Most purifiers will mention in their product description if they don’t make ozone, but not if they do.”
