The Bosch 6003C HEPA Cabin Air Filter is engineered to provide superior air quality within the cabins of Acura and Honda vehicles. Designed to meet High Efficiency Particulate Air (HEPA) standards based on ASTM D2986, this filter offers a filtration efficiency of 99.97% at 0.3 microns, effectively capturing microscopic pollutants such as pollen, mold spores, and common allergens. This high level of filtration ensures that the air entering the vehicle's cabin is clean and free from harmful particles, contributing to a healthier environment for occupants. Constructed with a multi-layer design, the Bosch 6003C incorporates a spunbond polyester layer combined with synthetic melt-blown fibers. This configuration enhances the filter's capacity to trap small particulates, providing comprehensive protection against airborne contaminants. The addition of structural ribs adds stability and durability to the filter, ensuring it maintains its shape and effectiveness over time. The recommended replacement interval for the Bosch 6003C is every 12,000 miles or as specified in the vehicle's owner manual. Regular replacement of the cabin air filter is essential to maintain optimal air quality and ensure the efficient operation of the vehicle's heating, ventilation, and air conditioning (HVAC) system. By choosing the Bosch 6003C HEPA Cabin Air Filter, fleet operators can enhance the comfort and health of their drivers and passengers, while also protecting the vehicle's HVAC system from potential damage caused by accumulated debris.
