Review on 🌬️ Enhanced KioudI – Nessbase HEPA Air Purifiers with Advanced Air Pretreatment System for Smoke, Pollen, Dander Elimination in Home, Bedroom, Living Room, Kitchen by Chris Pinkston

I have two dogs and not the best natural air circulation in my house. This machine made a noticeable difference pretty quickly, within a day or two of peaking! It's quiet at low frequencies, and if you prefer to use high frequencies the noise is almost like white noise to me. Definitely recommended for small spaces. I will buy another one to use upstairs in my house. The only downside was that this manufacturer's replacement filters weren't stocked at Revain when I checked, but there are details on how to change the filter right in the box and you can always use a different brand filter if you need/prefer.
