i have had this on for about 3 days now in an open-ish 750 sqft area. works like a charm. doesnt take away all the smell because, ya know, smell seeps into things, but the air is noticeably cleaner. this is important in a home with too many pets like i have. im happy with this purchase.

Love it - I purchased another one for downstairs!

AWESOME! First used in my bedroom with door closed. An hour later the room felt and smelled completely fresh. Used in the kitchen while cooking. It's interesting to watch the air quality monitor - immediately changed to red (dirty air). Maybe an hour later all cooking smells gone and air quality back to blue (clean air). This worked so well in my townhouse that I've purchased a second one to keep one upstairs and one downstairs. I highly recommend this purifier. It's small enough to move around your home and strong enough to quickly purify a room. Setup is super easy. Just unpack making sure that you remove ALL the plastic packaging. You'll need to remove the bottom and unpack the filter from the plastic wrapping. This gives you an opportunity to check out how the filter installs. Then find a convenient location out of the way, plug it in and press the on button. I run mine in auto mode. I deactivate the PlasmaWave function at night while sleeping. I'm just not comfortable being near it with that activated for extended periods of time. Now it may be perfectly safe, but that's just me. It's somewhat entertaining to see how certain activities and items trigger the "bad air" alert. Any type of fragrance (scented candles, cologne, cleaning supplies) sets it off. I noticed it when I was folding a seldom used blanket - maybe it's time to wash it and air it out.

I like this air purifier, because when the air is not clean, the blue ring will turn red that's your notification that your air is not filtered.And clean. it's a little noisy but nothing to complain about. Then, the ring will turn blue again when it's filtered.I like that feature.The dislikeThe blue ring acts like a night light.So if you're a sensitive sleeper, this may not work for you.
