Abstract: A device, method and system improve the breathable air quality of the environment in the region of a specific part of a body, such as around the mouth and nose area of a person buried in an avalanche. The device includes at least one inlet, at least one pump, at least one power resource, a controller, and at least one outlet. An inlet of the pump is constructed to act as a chamber. A first end of the chamber is connected to the inlet and a second end of the chamber is an opening towards the outside of the device. When the pump is activated, the pump will provide a vacuum in the chamber and suck air from the surroundings into the pump through the second end of the chamber and the chamber.
