Review on 🌬️ Kokofit H13 True HEPA Air Purifier: Eliminates 99.97% Allergies, Pets Hair, Odor, Smoke, Mold, and Pollen – Ultra-Quiet Sleep Mode – Black by Nicholas Peters

We live in Colorado and I bought this for my mom because where she lives there are a lot of drug addicts. She puts a towel under the door to keep the smoke out. She called me one night to say that the air purifier had started detecting pollutants in the air and she had checked and forgot to put a towel in it. After the device told her something was wrong, she put the towel back under the door and the air purifier cleaned the air in minutes. It basically runs at a low level until it detects pollutants in the air, then it runs at an accelerated speed until it cleans them again. peace of mind!
