Users Say: “So far I’m absolutely in love with this. I bought it because the apartment I moved into smelled musty and had a lingering odor from the several dogs that the previous renters had, in spite of cleaning and painting. Not only is the smell WAY better, but I realized once I plugged this in that it is the absolute perfect level of white noise. Now instead of running the whole apartment fan, I can plug this in by my bed and sleep soundly. Level 3 is a little loud but I can leave it running in the next room; level 2 is absolutely perfect. It also drowns out low levels of talking/music from the neighbors. Very happy with my purchase!!”

Bought this thing and ran it on high for a few days and noticed the cough lessening. I’ve kept it on low/medium for about two weeks now and my cough is completely gone. Highly recommend for asthma sufferers!”

Users Say: “We picked up two for a 2300 sq. ft. two-story house. Because the living room is open all the way to the second story, we’ve had problems distributing heating and cooling evenly from the central HVAC system. One of the filters sits in that area, and on even the lowest setting, it has equalized temps between both floors. That’s not why we bought the filters, just an added bonus. On the low setting, you can’t hear they’re running. Medium isn’t bad. High is noisy. It’s great to be able to turn off the idiot lights since we have one in the bedroom. Our allergies have been only slightly improved. The filters both say the air quality is already good. The living room filter does kick up if I bake or broil, and the bedroom filter quickly removed fresh paint smell.”
