Review Content Clean Air My wife has Asthma and Emphasymia and we use the air filter to remove dust and other particles in the bedroom so she can have a comfortable nights sleep. It is quiet and effective and Highly recommended. She has noticed a change and sleeps more soundly with the filter in operation. Its only downer is it emits way too much light at night. Excellent Product! Placed in the bedroom, husband suffers from allergies. Excellent results! Lights are a little bright for sleeping. Would love to have a dimmer switch to turn them down! Works great It works fine. Phone service over the phone I purchased an air filter from you and ordered needed new filter for it. It was easy to change and I ordered an extra one to have on hand. It was handled quickly on the phone and the order was received in a timely manner. Good and bad news Good news: This system filters air well, the best Sharper Image product Ive used for this purpose, and I have tried all back to the beginning. And it does not require washing the filter. Bad news: Accompanying instructions are poor and specialty phone reps that are supposed to resolve problems are not competent. Great product I purchased the air purifier about 6 months ago. LOVE it! So quiet and the filter lasted a really long time.
