Review on 🌬️ TONZE Large Room HEPA Filter Air Purifier - Dual 3 Stage True HEPA Air Filter, 3-Speed Fans, Up to 430ft² Purification Coverage, Quiet Sleep Mode, 99.97% Effective Against Pollen, Dust, Smoke, Pet Hair and Odor by Stephanie Thompson

My husband bought this for me because I have asthma and allergies and I always sneeze and cough at night. We put it in our bedroom and I was skeptical. I let it work non-stop all day, went to bed thinking I noticed a difference in just one day, but I've been using it for a week and a half now and my room is definitely better for my allergy response and I sleep better. I love that it has a very quiet sleep mode and then a low mode and a high mode. I'll just let it run non-stop and will definitely get replacement filters for it. I am very satisfied with this product even after a short time.
