Which Air Purifier Should I Buy?

Here are 7 of our favorite models for all your household needs

Nov 30

It seems like everybody these days is looking for air purifiers. Between pandemic fears, longer and longer allergy seasons, and pet adoptions on the rise, air purifiers have been in demand to help people cope with bacteria, pollen, and pet dander in the air.

But as with any retail phenomenon, there are far more cheap, poor-quality air purifiers flooding the market than really great ones. If you’re browsing and wondering, “Which air purifier should I buy?” have no fear. We’ve done the work for you.

Here, we round up the best air purifiers for just about any purpose, whether you’re looking to purify the biggest room in your house or you just need to do something about Fido’s hair wreaking havoc on your system.

Do Air Purifiers Really Work?

Before we go anywhere, we should answer the all-important question of whether or not air purifiers work. The short answer is: yes. Air purifiers use filters and fans to remove particles from the air and circulate cleaner air back into the room. However, some are more effective than others, and unless you’re using a purifier with a HEPA filter, you may not notice any changes to your allergies or asthma.

Additionally, it’s essential to set expectations for air purifiers. They work well when it comes to removing particles like dust, smoke, pollen, and other pollutants from the air, but they struggle to remove gases. So if you want to use an air purifier to get rid of that paint smell in your new living room, you may be better off just opening a window and spraying some Febreze.

Now that we’ve gotten that out of the way, let’s check out which air purifier you should buy.

Best Overall Air Purifier

Check all of the air purifier boxes with the AGH550 True HEPA Air Purifier. This purifier uses a True HEPA filter to remove 99.97% of airborne particles and a multi-stage filtration system to go above and beyond. The pre-filter captures large particles like hair and pet dander. The activated carbon filter absorbs pet odors, smoke, and chemical smells. The laser dust sensor kicks on quickly to automatically remove nasty stuff from the air. It’s a smart air purifier that can efficiently cover a 450-square-foot space, all while operating at a whisper-quiet 22dB. All of that is why it’s earned a 4.7-star rating on Amazon.

Get the AGH550 True HEPA Air Purifier for $234.99 (reg. $259).

Best Value Air Purifier

Air purifiers can easily run you hundreds of dollars. That’s why the TaoTronics 3-in-1 True HEPA Filter & UV-C Light Air Purifier is such a great buy at just $64.99. Despite the budget-friendly price, it doesn’t skimp on features. It uses advanced three-stage filtration and a built-in UV light to eliminate 99.97% of pollutants, such as pollen and dust mites. And it can freshen rooms up to 1,350 square feet.

Best Smart Air Purifier

What sets the Sensibo Pure smart air purifier apart from other models is Pure Boost™. This intelligent sensing technology actively monitors the air and kicks on when it notices the air quality has dropped. That way, you don’t have to wait until you start sneezing to turn on the air purifier; you can trust Sensibo Pure to do it for you. Using HEPA and carbon filters, it can tackle particles as small as 0.1μm to protect you against viruses, bacteria, dust, and more. Plus, with the Sensibo app, you can continuously monitor the air quality in any room in real-time.

Best Air Purifier for Pet Owners

If you have pets, you know the worst place for pet dander to gather is in your car. With the Airdog Car Air Purifier, you won’t have to worry about sneezing and getting dry eyes while driving your pets around. It uses advanced TPA® technology to deliver 14,800L of clean air per hour while the filter-free purification is 50x more efficient than a HEPA filter. But just because it doesn’t have a filter doesn’t mean it won’t work overtime. It can effectively sterilize bacteria and mold and remove smoke as well as pet odors and dander.

Best Air Purifier to Eliminate Odors

It’s just about the size of a lemon but works like a charm to decompose odor through natural photosynthesis, creating clean air. Whether a room smells from cat litter, shoes, food, or nearly anything else, the VentiFresh Plus can freshen it up fast. That’s why it was funded nearly 400% on Indiegogo and has earned rave reviews from Engadget, E27, and Techseen.
