Bosch P3922WS Workshop Cabin Air Filter

The Bosch P3922WS Workshop Cabin Air Filter features a multi-layer media that offers an 80 percent efficiency rate at 3 microns or greater, effectively keeping dirt, dust, pollen, and other airborne particles from entering your vehicle's heating and air conditioning vents. This particulate cabin air filter is designed to provide cleaner air for vehicle occupants while maintaining optimal HVAC system performance.

Three-Layer Filtration Technology:

• 1st Layer – Non-woven pre-filter layer captures larger particles
• 2nd Layer – Electrostatically charged microfiber layer attracts and holds elusive smaller particles
• 3rd Layer – Non-woven cover layer adds stability to protect the microfiber layer from damage and acts as an additional barrier to harmful elements

Performance Features:

• High pleat count provides greater surface area for higher filtration capacity
• Foam perimeter gasket (select part numbers where specified by OE) prevents harmful particles from bypassing the filter media
• Rigid frame (select part numbers where specified by OE) adds stability for peak performance and long service life

The Bosch Workshop Cabin Air Filter line is engineered specifically for professional installers and provides reliable filtration performance. Regular replacement of cabin air filters helps maintain air quality inside the vehicle and ensures proper airflow through the HVAC system.
