Review on PuraBreeze UV Air Purifier for Home and Office - HEPA Filtration, up to 1180 sq. ft. - Eliminates Odors, Smoke, Dust, and Mold by Philip Davenport

This air purifier sets itself apart from other models in its price range with premium features such as UV disinfection, a built-in air quality sensor and the ability to control it from anywhere in the world via WiFi. fi. It has an exceptionally user-friendly interface with a clear display and easy-to-use buttons. It is also capable of producing a lot of energy. The only reason this cleaner doesn't have 5 stars in my book is the fan noise. They're not unusually loud in DB terms, but have a slightly high resonance even at low power levels (all about sleep). Human ears are more sensitive to higher frequencies, and that sound was annoying to me, like a ringing in my ears. This is a disappointing flaw in a great device.
