Bosch P3955WS Workshop Cabin Air Filter

The Bosch P3955WS Workshop Cabin Air Filter is engineered to provide superior air quality protection for your vehicle's interior. This high-efficiency particulate filter captures up to 99% of airborne contaminants 3 microns or larger, preventing dirt, dust, pollen, and other environmental particles from entering through your HVAC system.

• First Layer: Non-woven pre-filter captures larger particles and debris
• Second Layer: Electrostatically charged microfiber layer attracts and traps smaller particles including pollen and allergens
• Third Layer: Non-woven cover layer provides structural stability and additional barrier protection

Key Features:

• 99% filtration efficiency at 3 microns or greater, 80% efficiency for particles under 3 microns
• High pleat count design provides maximum surface area for superior filtration capacity
• Foam perimeter gasket prevents contaminants from bypassing the filter media
• Measures 10.2" x 11.4" x 1.8" for precise OE fitment
• Polyester filter media construction ensures durability and long service life

Regular replacement of your cabin air filter helps maintain optimal HVAC performance, reduces strain on system components, and ensures clean, fresh air for all vehicle occupants. Bosch recommends inspecting cabin air filters annually and replacing according to manufacturer specifications, or more frequently if driving in heavy traffic or dusty conditions.
