The Medisana Air continuously and effectively cleans the air from fine dust, dust, pollen, bacteria, and even odors. The core of the Medisana Air is a 3M antibacterial fine dust filter with additional activated carbon filtration. The Medisana Air operates on the principle of convection, promoting the natural exchange of air masses. It automatically switches from day mode to whisper-quiet night mode. This innovative air purifier is a discreet yet efficient way to ensure fresh air in enclosed spaces around the clock. The patented LED dust traffic light ensures that the air is optimally filtered and indicates the level of pollution or when a filter change is necessary. The Medisana Air can be powered using the included power adapter and USB cable, as well as standard power banks. With the help of power banks, you can flexibly and individually decide where your Medisana Air should be optimally placed in the room (power bank not included).
