Using a super blend of impregnated activated carbon, this home air filtration system is designed for addressing chemical vapor and odor related issues, as well as VOC’s such as formaldehyde. The room air purifier uses a powerful 560 CFM Swiss crafted motor to draw air through 18 lbs. of true weight carbon in a 2″ deep carbon bed, to remove odors and chemicals. The quietly running system passes air through a prefilter, which keeps the carbon clean, and allows the impregnated carbon to do its job. Once through the carbon, the air is then filtered of fine particulate matter when it goes through the Hepa filter. A specially designed pressure seal ensures the proper elimination of particles and odors, with no air bypassing. Available in Cream enameled metal housing. Assembly level/degree of difficulty: No Assembly Required.
