I really like this unit. It really does its job by cleaning the air. Its very quiet and has a few modes that increases the fan speeds when it detects unclean air. My only bad thing I have to say is that my previous unit came with a remote control. This unit does not have it. It would be a nice addition for this unit.
I bought this last month. I've been enjoying the cleaner air quality. Very easy to rinse off the outside filters, and, put them back in. No dust particles when the sun shines through the windows. Satisfied customer.
I can't really tell much of a difference in my indoor air quality or odors. My allergies seem to be a little worse lately now that I have the Shark but maybe the pollen count is higher.
I ordered an Eden Pure a few months ago and it left an odd odor in the living room where I had it. The Shark is better than that. Maybe I'm expecting too much.
