MANN-FILTER is introducing a new cabin air filter with three-layer technology. The first layer consists of a polyphenol coating that locks many allergy-causing allergens, preventing these from entering the cabin. The second is a charcoal layer with activated carbon. This layer adsorbs odor and toxic exhaust gas. Third layer, the dust layer, consists of non-woven material with an anti-microbial function that removes fine dust and particles. The anti-microbial function prevents bacteriaand mold growth, according to the company. The non-woven filter media can filter particles smaller than 5 μm, which are 200 times finer than human hair.

The new design successfully protects the cabin environment from outside gases such as nitrogen dioxide, fuels and ozone toxins, according to the company. The cabin air filter, which differs from any type of engine filter, is designed to keep the inside of the vehicle free from harmful contaminants. These contaminants can consist of:
- Spores.
- Dust.
- Pollen.
- Exhaust.
- Pollution.
- Gases.

All MANN-FILTER cabin air filters provide exact fit and seal specifications to various vehicles and their applications, according to the company. MANN-FILTER is constantly optimizing the filter media and adapting them to meet increasing requirements. Choice of filter media is linked to the vehicle manufmanufacturer’s specification and space available in the vehicle.
