Perfect for my room

Little loud on highest setting (has low, medium and high) but not a huge issue for me as its drown out by my AC and other fan in my room. However got this because I live with two cats who are in my room 95% of the day and it being carpeted makes it a sponge for dust and cat hair. In the few days I've had it already sleeping better and waking up more refreshed instead of waking up with sinus congestion almost daily. Perfect for a room that needs extra purification, using it along with some Snake plants and its perfection. Highly recommended.

Decent results %26 reasonably priced

Ive only had my purifier for a little over a week, and so far I really like it. Its as simple as installing the filter and plugging it in. I could tell a difference shortly after using it. I suffer with seasonal allergies and since using it I dont seem to be as stuffy every morning. It says to change the air filter every 4 months, but I plan on changing mine every 2-3 at most but thats a personal preference. Replacement air filters are reasonably priced. The only complaint Ive seen some people say is about the sound. It does have a constant hum sound, kinda like a fan. If your someone that falls asleep with a fan on at night or dont mind slight background noise while you sleep then this might be for you.

This air purifier by Honeywell is a compact unit. The device fits perfectly on my dresser allowing 6 or more inches for good circulation. The air purifier is lightweight and the noise level is less than a fan. I use this to clear the air about three times a day, ans am noticing an improvement in air quality. I highly recommend this Honeywell air purifier.
