Review on BONECO W200 Air Washer: Humidifier and Purifier for Improved Air Quality by Akihiko Kichiro ᠌

We've been using it for a little over a week. Works 24/7. It became really easier to breathe in the room, the mucous membranes stopped drying out. But, a small room with closed windows and doors humidifies up to a maximum of 42% in daytime mode from morning to evening, at a temperature in the room of 26. If you open the window, the humidity immediately drops to 38%.
