Abstract
An apparatus (100 and/or 200) and corresponding method (500) for air sterilization and disinfection can include an electronics and control module (110 and/or 210), a means for drawing air from the surrounding environment into the apparatus (120 and/or 220), an air management chamber (130 and/or 230), and a housing (170 and/or 270). The means for drawing air from the surrounding environment into the apparatus (120 and/or 220) mobilizes latent pathogens in the environment and draws them into the apparatus (100 and/or 200) for sterilization and disinfection. The air management chamber (130 and/or 230) provides for exposure of the airborne pathogens to UV radiation, via UV LEDs (150 and/or 250), with a dosage sufficient to penetrate the cell walls and destroy the pathogens. The electronics and control module (110 and/or 210) powers the apparatus (100 and/or 200) and interfaces with the electronic components. The housing (170) forms the outer shell of the apparatus (100).
