ABSTRACT:
A battery powered portable human body carrying electronic human breath filtration device is an electronic nose mask and is the most ideal alternative to conventional filter paper type nose mask. It utilizes electronic ionization technique and electrostatic field to remove air borne particles, dust, pollens, contaminants, bacteria, viruses, toxic chemical, fume and tobacco smoke from human inhalation and exhalation breath. It interacts with human breathing action as the air flow driving system to move the inhalation and exhalation breaths through the electronic filter elements, in addition to a front louver cover and a rear louver cover's protection as pre-filters. The system requires very low running current and uses small batteries usually found in household electronics. This filtration system is light weight with negligible air flow resistance and is integrated into the nose mask which is connected to a pocket size control system via a connection cable.
