Customer Review: Quiet!!! Works great...
After reading reviews about how loud some other units were, I decided to try these. I ended up getting two of them, one for the bedroom and one for the living room. The low setting (which we use in the bedroom) is practically silent and you forget that it is running. The medium setting is a little bit louder, but you still forget it is on unless you are paying attention to it. The high setting is much louder, but still acceptable. I did notice a huge difference in my allergies within a day or two and haven't reverted back to my crazy allergies since he filters arrived.
Customer Review: Good for allergies
As other have said, the first day you run it, you will get a wierd smell, be prepared. But after that it's great. During the time I am not in the room I run it on high, when I sleep I run it on low. I have 2 dogs, and all of us have allergies, and this has helped.
