Review on 🏢 isinlive AC201B Air Purifier: Powerful HEPA Filter for Smoke, Pollen, Pet Dander; Removes Odors and Dust; Low Noise with Night Light; Ideal for Home, Office, Bathroom, Kitchen, Living Room - Black by Bianca Mares

We bought this to remove the smell of cat litter. Since we live in a small apartment, we could only put the tray in front of the front door. So when you get home, you will be surprised by the smell of the tray because everything is enclosed in such a small space. After a few hours, the air becomes absolutely clean! This worked much better than I thought. As an added bonus, it's very quiet. I could see this happening in someone's bedroom without disturbing your sleep.
