Query: Wake up and smell the clean air...

I love this filter! After one week I was shocked at how much dirt it cleaned up from our air. You do have to replace the filters but it is totally worth it.If it is in the room with you and you are trying to talk or watch tv it is very NICE to be able to turn it down, to hear better without having to turn it off. Don't get me wrong, even the high setting is NOT that noisey. I highly recommend this air cleaner for the price and for the quality.
