Cabin filters have three-layer technology

Nov. 7, 2012

MANN+HUMMEL USA Inc. has developed a new three-layer cabin air filter using polyphenol, a natural plant extract, to lock allergens and prevent them from entering the vehicle.

MANN-FILTER introduced the new cabin air filter at the Automotive Aftermarket Products Expo (AAPEX) Oct. 30-Nov. 1, 2012, at the Sands Expo Center in Las Vegas, Nev.

The three-layer technology consists of a first layer of a polyphenol coating that locks allergens. The second layer is a charcoal layer with activated carbon that absorbs odor and toxic exhaust gas. The third layer, the dust layer, consists of nonwoven material with an anti-microbial function that removes fine dust and particles.

The company says the new design successfully protects the cabin environment from outside gases such as nitrogen dioxide, fuels and ozone toxins.

All MANN-FILTER cabin air filters provide exact fit and seal specifications to various vehicles and their applications.
