Abstract
The present invention is a compact and portable personal ultraviolet air irradiation system having an ultraviolet air irradiation unit, a breathing tube, and a face mask. Unfiltered air passes through the ultraviolet air irradiation unit and is purified to ensure biological material has been neutralized by utilizing UV LEDs in the germicidal wavelengths of 100-280 nm. The ultraviolet air irradiation unit may further purify air of air particulates, gases, vapors, and biological material by utilizing a HEPA filter. The ultraviolet air irradiation unit may provide variable pressure to the mask to meet the breathing demands of the user. Flow through the ultraviolet irradiation unit may be reversible to irradiate the exhalations of a user who may be infected with a virus or other disease spread through exhalations.
