Air purifier expert's opinion - Aerify

"The Boneco U250 is incredibly easy to operate, and it produces a lot of moisture. I really like how simple it is to refill the water tank. You can set the desired humidity and the intensity of the mist by using touch-sensitive controls. The included water filter is extremely economic and can last up to 6 months." - David, customer support.
