STUDY AND EVALUATION OF ANTI MICROBIAL ACTIVITY OF FILTER COATED BY NANO SILVER IN AIR-CLEANER DEVICE

Abstract

    Air purifying methods using either ozone or ultra violet light are not popular applied due to their negative human heath impact. Recent research results show that air purifying method which uses photocatalytic process does not harm the environment, on the other hand offers the higher treatment efficiency. In addition, photocatalytic method can remove particles and kill micro-organisms only with the presence of oxygen while not introducing any particular oxidizing agent into the air.
