Abstract: A DC power source operating portable human body carrying potential feedback electronic human breath filtration device is an electronic nose mask with directional ionic air filtration control and is the most ideal alternative to conventional filter paper type nose mask. It utilizes potential feedback electronic ionization technique and electrostatic field to remove air borne matters from human inhalation and exhalation breath. It has UV germicidal function and a micro electric fan to provide positive air pressure. It utilizes electromechanical potential feedback technology to improve the rate of ionization at lower voltage level to minimize the generation of Ozone; a moisture collection feature to absorb the condensation from the user's breath. It is light weight and connected to a pocket size control system via a connection cable and has an ionization flux sensing device for user to verify the present of the ionization.
