Best Air Purifiers of 2025

"I recently purchased the Levoit Air Purifier, and it has been a game changer for my bedroom! I struggled with airborne dust and pet dander, but after using this purifier, I noticed a huge difference in my air quality. It comes fully assembled, and I could start using it right away. It's compact and fits perfectly in my room. On the low fan setting, it's hardly audible, which I appreciate. I highly recommend it!"

"I bought this because I have allergies and asthma and heard good things about purifiers. I've had it for about a month and a half now, and I noticed a big difference in air quality. I usually keep it running 24/7, and the noise isn't bad. I vacuum the filter every week or two. The only time it's too loud is on high, but I use that setting when I'm out to pick up more particles. It has helped reduce my stuffy nose at night significantly!"

"I absolutely love my new air purifier! It does an incredible job of keeping the air fresh and clean, and the soothing sounds it produces are a total game-changer. It creates a peaceful atmosphere perfect for relaxing before bed. Plus, it quickly eliminates odors, allergens, and dust, leaving the air noticeably fresher. I'm so happy with it that I just ordered one for my daughter at school!"

"For its price, I find this air purifier amazing. The reusable filter saves on the replaceable one, and it's much quieter than other brands. The air quality detection is spot on. The only downside is that the LED light can't be turned off, which makes it uncomfortable to use at night in the bedroom."

I've really enjoyed how effectively it cleans the air."

"I’ve had the Blueair for about a month now, and I am completely impressed with its functionality. Most of the time, the air quality stays at 0, but it quickly detects changes when I cook or light a candle. While the highest setting (4) is loud, I usually run it at 2 when we're in the same room, which is very quiet. The app is easy to use. Overall, I’m very satisfied with my purchase!"

Overall, this air purifier has exceeded my expectations. I highly recommend it!"

"We got this for my husband, who suffered from severe sinus headaches at night. Since we started using it, his sleep has greatly improved; he falls asleep quickly and sleeps through the night. I can also adjust the fan sounds from soft to loud, which helps with my Tinnitus. After a month, the air quality in our loft improved significantly, and we've noticed less dust. I'm considering getting another for my son with asthma and allergies!"

This unit is ideal for small spaces like bathrooms."
