The MAHLE CareMetix Cabin Air Filters feature five layers of protection to eliminate odor, pollen, soot, and fine particulates. The filters are constructed with S5 broadband technology that encompasses a high-performance particulate filter layer, a molecular layer, an engineered activated carbon layer, a bio-functional layer with activated carbon, and a protective layer. The cabin air filters incorporate an anti-bacterial coating; removing harmful micro-organisms and preventing them from spreading throughout the filter material. CareMetix filters also remove mold spores and prevent mold build-up on the filter itself.
