HONEYWELL 83331 Silent Surround Type HEPA Air Cleaner  Product Reviews

"The two lowest settings are pretty quiet. The high setting is loud for some people, but it definitely helps to put me to sleep with it's hummmmmm. This is a fantastic product."

"These air cleaners are inexpensive. I was looking at getting a newer unit but it cost $170. I was able to buy two of these for less. They are not silent. The fan has three speeds. The lowest level is quite almost tower PC sound. With the fan on High it is loud as a box fan on high. I purchased these to keep dust down and pet fur out of the air. "

"Seems like it works just great. Helped with our mold problem and maybe even the dander from the pets. It isn't perfect or anything, but I do like how it has 3 settings. Reasonably priced, also."

"They should definately not call it a "silent" air cleaner. The noise level is totally bearable though. It sounds exactly like a window AC unit on high. On low the setting I put it on to sleep it sounds like an ordinary fan. I woke up feeling great this morning. I hope they invent a hepa filter that you can wear around all day!! Allergies suck!! It works great!!! I would say if your in the market for a "true hepa" filter for under $100 this would be it. I got mine for $59 +shipping. On another website it lists for $159."
