I bought this product in preparation for hunkering down indoors during the colder months of the pandemic. So far this seems to be working out very well. When I first set it up and cut it on I had a blue circle indicating clean air so I wasn't sure if it was actually doing anything...until I made bacon. The ring turned red and the machine kicked on and worked to clean the air. The kitchen is open to the living area and it worked fast to clean such a large area. The purifier is sleeker looking than others I have seen on the market. It's a little large, but not a huge problem. It is very loud when set on high fan which is to be expected. When it is on auto, it sounds like a white noise machine turned on low that actually has helped me sleep.
