Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy, but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ‘em) products and single out the most convincing ones. While we’ve written about homeopathic allergy cures and excellent (but expensive) air purifiers before, we’ve gone deep here on the best air purifiers you can find on Amazon. (Note that reviews have been edited for length and clarity.)

Best three-in-one HEPA air purifiers

Pure Enrichment PureZone 3-in-1 True HEPA Air Purifier

“Very attractive and functional piece of hardware. You can tell this is a quality piece right out of the box just by the decent weight of the product. It is not cheaply made. Got that luxury look to it; with touch-sensitive buttons, smooth top grill, and white all-around finish. Got it up and running in one minute and I can tell it’s working by the fan blowing air up top and the sucking of air into the two sides and bottom slits. A true plus is the three-in-one filter, which makes it super easy to replace. This is an excellent unit and I would highly recommend it for any bedroom or small area!”

GermGuardian AC4825 3-in-1 HEPA Air Purifier

“Although I dust and vacuum fairly often, I noticed I still had issues with my asthma when spending periods of time in my room. It wasn’t until nursing school when I started to learn about HEPA filters for hospitals that I realized proper filtration could be a game changer for my symptoms. I’ve had this air purifier for about five months now, and I would buy one for every room in my house if they were a little less expensive. My symptoms aren’t nonexistent, but they’ve definitely improved and that’s all I could ask for. This particular filter that I’ve just replaced is completely coated with a thick layer of dust bunnies (and goodness knows what else) after only a few months of use. My symptoms make total sense now that I see how much stuff gets left behind when cleaning.”

Best air purifier with a permanent filter

Envion Therapure TPP240 Permanent Filter Air Purifier

“What’s not to love about this purifier? I have sinus issues and deal poorly with both too much pet dander & pollen/allergies so I run several air purifiers. We have both true HEPA filters and those like this one which are ‘HEPA-type’ and have permanent filters. Honestly I don’t see that much of a difference other than the fact that I spend a fortune buying replacement filters for my true HEPA filters. I think I’m going to replace them all with permanent filter machines instead.”

Best air purifier with a washable filter

Winix 5500-2 Air Purifier with True HEPA With Washable AOC Carbon Filter

“The filter is washable, which is wonderful, it means less cost in upkeep … It looks sleek in black and isn’t very noticeable at all which is an aesthetic plus. More than looks is how well it performs, it really pulls the junk out of the air so you can breathe much easier.”

Best air purifier for smokers

VEVA 8000 Elite Pro Series True HEPA, With Four Activated Carbon Pre-Filters

“Not sure if the manufacturer will appreciate this review but I’m pretty sure I am not the only cigarette smoker out there so here goes. When we moved into our new house, I chose my 10-by-15-foot home office as the only room I would smoke in. I bought this product to try to spare my husband from that odor in the rest of the house. I waited 30 days to post this review and I can tell you it made a massive difference. It doesn’t completely remove the smell but I would say it cuts it by 80 percent at minimum. I run it on low continuously. It’s quiet, doesn’t affect phone conversations, and I have not seen a difference in our electric bill.”

Best air purifier for asthma and allergies

Fellowes AeraMax 100 Air Purifier, True HEPA Filter

“I found the recommendation for the AeraMax on the Asthma and Allergy Foundation web site. Since I have family members with Asthma brought on by allergies, the foundation’s backing was priority. It runs quietly and is currently on ‘auto’ mode. One less thing for me to worry about. I love that all the indicators are located on the front of the unit and will take the guess work out of when to replace the filters.”

Best air purifiers for pet allergies

LEVOIT LV-PUR131 Air Purifier with True HEPA Filter

“I only run this unit at night on sleep mode as I am gone 12 hours a day on my job. I have four dogs that sleep with me and I have to honestly say that just the two nights I have used this purifier has made a tremendous difference. I am not waking up with a runny or stuffy nose and breathe clearer if that makes any since. Even though it is rated for 300 square feet, my room is 400 square feet with 10-foot ceilings and this seems to be more than sufficient. I recommend it to anyone that needs to purify their air space.”

Winix WAC9500 Ultimate Pet True HEPA Air Cleaner with PlasmaWave Technology

“I have three dogs: a shepherd who sheds like it’s his job, and two others with ‘hair’ that rolls like tumbleweeds across the floor. This works great for odors [and] does well with removing the dog hair from the air. I moved it upstairs to control cat hair and odor (did I not mention the cat who won’t come down from the second floor?), works great. Need to get another one for downstairs, there is a noticeable difference in how quickly dust and dog hair accumulate without the unit down there. Easy to clean and fairly quiet.”

Best air purifier for mold

Alen BreatheSmart FLEX Air Purifier with Filter for Mold & Bacteria

“I found via lab results that mold levels were detected in my home even though it was not visible; it was in the air and I suspected it was due to the condition of the foundation of my home. I had been suffering from repeated upper respiratory and sinus infections resulting in having to take antibiotics four times last year. Since I started running the Alen BreatheSmart Flex Air Purifier a month ago, my symptoms have declined significantly.”

Best 360-degree air purifier

Honeywell 50250-S True HEPA Air Purifier

“We’ve had this running day and night for three years and it’s in great condition. There are no strange rattling noises or clogs like you see in some other air purifiers. It provides a nice ambient noise and isn’t too loud (on the lowest setting). We have noticed a significant decrease in our allergies and in the dust in our home. Replacing the prefilters every three months is a breeze — you just unscrew the bottom, unwrap the old one, and wrap the new one onto the HEPA filter.”

Best air purifier with a night-light

Levoit Purifier With True HEPA Filter

“After having used this for a few months, I can confidently say how great this air purifier is. With the recent wildfires, the air quality in Oregon has been very unhealthy and at times hazardous. Combined with the heat, we have no choice but to leave our windows open or the air conditioner running. We also have hardwood floors, so the dust, dander, and pet hair get kicked up very easily. This air purifier has made a world of difference! No smoke smell in the room it’s ran in, and I don’t have to worry as much about my son constantly breathing in the smog.”

Best desktop air purifier

Holmes HEPA Type Desktop Air Purifier

“Exactly what I was hoping for. Fairly quiet and the air-cleaning was noticeable within the first hour of running it. I bought this for my office, but I’m not sure my wife will let it out of the house after the first 24-hour test at home. Our living room is nearly 300 square feet, and the air was noticeably much better there. I am certain it will be fine in my 200-square-foot office, which also exceeds the maximum recommended room size. On low, the noise is no more than some older computer towers. Medium is an okay white noise, but a bit distracting when trying to watch TV at a low volume.”

Best portable air purifier

GermGuardian AC4100 3-in-1 Air Purifier With HEPA Filter

“I generally keep my windows closed, but on cooler nights, I like to leave them open, especially in my bedroom. During the summer, I often use the AC, so pollen in my bedroom isn’t a major concern compared to household dust. I am happy to report that this wonderful device combats both with ease. I placed this thing on my desk, turned on the UV light, set it on medium fan speed, closed my door and left for a few hours. When I came back, my room smelled fresh and clean. The air felt lighter and easier to breathe. I was amazed. The difference this thing makes, as an allergy sufferer, is night and day. I get better sleep at night and am less congested during the day. That, right there, makes this purchase totally worth it for me.”

Best large-area air purifiers

Fellowes AeraMax 300 Large Room Air Purifier

“I rarely write reviews. But for this purchase — one of the best decisions of my life — I simply can’t keep quiet. I’ve owned many filters previously, and could never tell the difference in air with or without them. They were noisy and some smelled of plastic. But this AeraMax 300 completely exceeded my expectations! It is soooo good that I immediately purchased another one. Now I have two, one in the bedroom, and another one in the living room. Both on at all times. Very quiet. Even when I manually boost them to max, they are not as noisy as many other brands. I just love them!”

Rabbit Air BioGS 2.0 Ultra Quiet HEPA Air Purifier

“Wow, for once something actually works as described! Unbelievable how amazing this purifier is! From just minutes of turning it on auto mode, it was already starting to freshen up my room. The pet smells were gone almost immediately! I have parakeets, a dove, and two cockatiels, as well as two cats, and this is already making a massive difference in my room. I am so loving it! So glad I took the jump and spent the money on this product, it really is worth it when you think about the filters lasting for so many years, and easy to clean. At the rate that it works, it is well worth the money.”

Best-looking air purifier

Coway AP-1512HH Mighty Air Purifier

“Excellent air purifier for our living room. Love the colored air-quality indicator and the auto feature, so it kicks on when something is detected in the air, but is in standby the rest of the time (there are also several continuous settings). It’s aesthetically pleasing as far as air purifiers go. I scoured reviews online before purchasing and am very happy I settled on this one.”

Best plug-in air purifier

Hamilton Beach TrueAir Plug-Mount Odor Eliminator

“This product is a godsend! My sister has a dog and isn’t the cleanest person. Her mess combined with 100-degree California weather left her room smelling like a hot trash can. She’s immune to the smell, but as her housemate, I could smell the foul order oozing out of her room. So, after her inaction, I took matters into my own hands and ordered the air plug order eliminator. OMG! After plugging this baby in for an hour, the smell was gone. The filter pushed out all the dog and hot-trash smell in her room and replaced it was a light, flowery fragrance.”
