Negative Positive
Title: 4000
Review: The reason I give it 4 out of 5 stars is because I'm not sure how well it works compared to others and the slight noise it makes.It says virtually silent but if you turn it anywhere from halfway to all the way up, it makes a buzzing noise than can be very irritating.The ozone smell can be really strong but I guess that proves that it's working.I bought mine used from Ebay and I didn't think it worked. The change collection sheet light never came on and there wasn't anything really on the sheet. Well, that's until I moved into a house with a mold problem. The light goes off even before the 30 days (the house I'm living in is old so there's lots of mold and mildew) and the collection sheet is very dirty.I have a problem finding extra collection sheets for this item.All in all, it's a good price and it does pull things out of the air.
