The MICROCON® CD and PD air filtration systems are specifically designed for the removal of airborne pollutants and gaseous contaminants from indoor environments. Either ceiling mounted (CD) or portable (PD), air is drawn through a high efficiency HEPA filter, past germicidal UV lamps before being exhausted through two activated carbon filter cells. Clean air, free of particulate and gaseous odors, is reintroduced to the room.
