HEPA Premium Cabin Air Filters

The Bosch HEPA Premium Cabin Air Filters are designed to clean the air that enters a vehicle through the heating, ventilation and air conditioning (HVAC) system by trapping fumes, pollen, dust and pollutants, and preventing them from entering the vehicle. This is especially beneficial for passengers who suffer with allergies and other respiratory problems, according to Bosch. The filter features a triple-layer construction that includes a support layer, the HEPA layer and a static cotton layer. The melt-blown electrostatic HEPA layer is made with very dense media that provides greater particle-trapping capabilities than non-HEPA cabin air filters. The filters have a 99.97 percent efficiency at 0.3 microns, according to Bosch.
