Review on COLZER Air Purifier Electronic Detection by Melanie Lang

Product works fine. I bought it so the new neighbors would appear to be heavy smokers. Smoke seems to be coming through the walls. This product seems to work in a small space, so it reduces the amount of secondhand smoke in the air. The door must also remain closed for best results. My main complaint is that sometimes it doesn't work. Sometimes the LED screen flickers like it's shorting out or something. In general everything is excellent!
