Air purifier expert's opinion - Aerify

"The Boneco U350 is an easy-to-use humidifier that produces a lot of moisture. I really like how simple it is to refill the water tank and the programmable hydrostat is a fantastic feature. The included water filter is extremely economic and can last up to 6 months." - David, customer support.
