Bests & Worsts Reviews from Amazon

I've been running this for a week. I will definitely be updating in a few months to see if filter turns dirty as its supposed to but so far I can comment on what I like about it. It is quiet. At first, when you turn it on, you do hear a fan noise but after awhile I didn't hear it at all. It's small so you can place it anywhere without taking up to much space.. I used to have a fairly large filter that sat on my floor, so I am happy about the size. I hope it's working .. it's winter here & really cold so I haven't been opening the windows to air out the house as much as I would like. Trusting this to help clean the air. Instructions were easy to follow.. Not much to it really.. you just press the button.
