Bosch P3671WS Workshop Cabin Air Filter

The Bosch P3671WS Workshop Cabin Air Filter delivers superior air quality protection for your vehicle's HVAC system with professional-grade multi-layer filtration technology. Engineered to capture dirt, dust, pollen, and other airborne contaminants, this particulate filter offers an impressive 80% efficiency rate at 3 microns or greater, ensuring cleaner air for you and your passengers.

Advanced Three-Layer Filtration System:

• First Layer: Non-woven pre-filter captures larger contaminant particles before they reach the interior layers
• Second Layer: Electrostatically charged microfiber layer attracts and holds elusive smaller particles that standard filters miss
• Third Layer: Non-woven cover layer adds structural stability while providing an additional barrier against harmful environmental elements

Premium Engineering Features:

• High pleat count design provides greater surface area for increased filtration capacity and longer service life
• Foam perimeter gasket prevents harmful particles from bypassing the filter media
• Mold-resistant multi-layer media ensures maximum performance and durability
• Meets High Efficiency Particulate Air (HEPA) standards based on test standard ASTM D2986

The Bosch P3671WS helps maintain optimal HVAC performance while protecting downstream components from contamination. Signs that replacement may be needed include reduced airflow through your ventilation system or unusual fan noise. Bosch recommends inspecting cabin air filters at least once a year and following manufacturer-specified replacement intervals.
