This invention relates to imparting antimicrobial properties to flexible air ducts, flexible connectors, grills and air disc valves used in ventilation systems by means of a silver particles (2) containing nanopolymer capsule (1) technology, and to antimicrobial venting system members obtained as a result of this technology. This polymer capsule (1) is both a safe and healthy antimicrobial, and a powerful antibacterial and antifungal. Furthermore, it functions via a catalytic mechanism and resultantly docs not release the silver ions. This, in turn, eliminates the problem in which silver ions released from venting systems impose a threat against other microorganisms present in the nature and bioaccumulate in the body of living organisms.
