Great Air Purifier for the price. Setup is quick and easy out of the box and using the Air purifier couldn't be easier. Has nice menu on the device itself or you syng with the app (actually worked! unlike most other products) and also can use voice control through Alexa with is a dream. In terms of actually purifying the air it DOES work and works very well. You can feel the air quality is better even after the first time you run it. People with allergies or other breathing problems will definitely benefit from this. Size is good, quality is good, noise level is good. Overall this is an easy to use Air Purifier that does it's job well and actually works!
