Review on Powerful 4000mAh Portable Ozone Generator and Air Purifier for Refrigerator, Pet Kennel, Car, Wardrobe - Type C Charging, Effective Deodorizer for Shoe Cabinet by Elizabeth Adams

I bought it and used it immediately for 5 days. My big room has gone through so many changes that it seems like this little item cleans a lot of the air. great advantages of ease of use, fast charging and long-term use. Noise? Something like that does not exist. When you want to hear a sound, place it right in front of your ear to feel it. Otherwise you cannot hear it. If you are sensitive to air purification, give it a try! Very helpful.
