Nanofiltration Devise for Deactivation of Air-Filtered Pathogens on the Surface-Treated Filter Material

Abstract: a nanofiltration device for inactivating droplet-transmitted pathogens. the microdroplets are captured by filtering contaminated air on a filter material/paper with the nanofibrillated cellulose and/or nanocellulose surface treatment containing antiseptic metal ions and an adjuvant in the retained residual water. the air is sucked into the openings of the nanofiltration device located at the bottom and passes into the centre of the filter cartridge, in which a germicidal emitter emits radiation in the uv-c range of the electromagnetic wavelength spectrum is mounted. subsequently, it flows through a filter paper containing salts of antiseptic metals, from the centre of the radiator outwards through a filter paper hermetically inserted into the filter cartridge, folded harmoniously-shaped so that its surface is maximally and entirely irradiated with uv-c radiation. antiseptic ions diffuse into the contaminated microdroplets which with uv-c radiation deactivate viruses and disinfect bacteria. subsequently, the droplets dry out, and the deactivated viruses and bacteria are carried away by air, which, with the help of adjuvants, receive the human body and increase the population's immunity.
