I can breathe clearly

I have a large bedroom and this works well to clear the air. I haven't had to take an allergy pill since having this on full blast each night. I love the white noise sound as I drift of to sleep. Ordered one for the kids room and one for the kitchen to get rid of food smells. Wish I had ordered these years ago!

Great For Small Baths, Especially If You Don't Have A Bathroom Exhaust

With 3 fan speed settings, it's not too noisy, especially if you leave the bath door closed after using. HEPA filter works. I've been looking for a solution to small bath odors, especially in the downstairs bath where guests would frequent. Downstairs baths are where you need exhaust the most but you have to exhaust through the wall. Other solutions like scented candles or plug-in do not work well. When turned on, this machine filters orders extremely well and also creates air flow in the small bath. Very effective solution to a common problem.

Great for allergies and odors! Love it!

I love this little product - I bought 2. I don't have a lot of space in my house and one fits nicely on my countertop in my kitchen and I have the other one in my bedroom. My husband said he was less congested from his allergies in the morning when we had this running during the night. It's pretty quiet and didn't bother us being on while sleeping. I don't have an exhaust fan in my kitchen so it does a nice job of getting rid of food smells after cooking. I don't like to cover up smells with candles or air fresheners and I feel like this air purifier actually gets rid of the odors. I also have two big dogs in the house and I think it helps with their smell too. I also like how it looks and its simple to use.
