Abstract

PURPOSE: A nano-silver photo-catalytic high-efficiency particulate air(HEPA) filter is provided to extend the life of the filter by improving abrasion resistance characteristic. CONSTITUTION: A nano-silver photo-catalytic HEPA filter includes a polymer thin film containing nano-silver. A nano-silver photo-catalytic solution is prepared by photo-depositing nano-silver to 3.5% titanium dioxide. The nano-silver photo-catalytic solution is finely sprayed to HEPA filter yarn or cloth to form the polymer thin film on the surface or the cloth of the HEPA filter. The polymer thin film is reacted with oxygen in the air by the oxygen catalyst of the nano-silver in order to generate superoxide ions(O_2^-) and hydroxyl radicals. Sterilizing and deodorizing operations are implemented.
