The Bosch PC1838 is a WORKSHOP cabin air filter designed to trap airborne contaminants that enter a vehicle's passenger compartment through the heating, ventilation, and air conditioning (HVAC) system. It captures dust, pollen, mold spores, and other particulates to help maintain cleaner air inside the cabin.

Key Features:

• Traps dust, pollen, and other airborne particulates before they enter the cabin
