I love this thing. The gauge on the front that shows what the quality of the air is at is amazing! It definitely works too because the moment we start cooking the number goes way down and the filter starts working on over time until it gets back to 100. Helps keep dust away, and I think it helps with our cat hair (but I’m not sure bc cat hair still turns up everywhere). Also love that I don’t have to change the filter so I dont have to keep up with buying the filters. Worth the money!
