Bosch P3958WS Workshop Cabin Air Filter

The Bosch P3958WS Workshop Cabin Air Filter is designed to provide cleaner, healthier air for vehicle passengers by filtering harmful contaminants before they enter the cabin through the HVAC system. This particulate cabin air filter features advanced multi-layer construction engineered to capture dust, pollen, and environmental particles effectively.

Key Features:

• Multi-layer filtration media captures 80% of dirt and environmental particles
• Non-woven pre-filter layer captures larger particles
• Electrostatically charged microfiber layer attracts and holds smaller particles
• Non-woven cover layers protect the microfiber core and add structural stability
• High pleat count provides greater surface area for enhanced filtration capacity
• Foam perimeter gasket ensures proper sealing and prevents bypass
• Direct OE replacement design for easy installation

Bosch recommends inspecting cabin air filters at least once a year and replacing at manufacturer-specified intervals. Signs that replacement may be needed include reduced airflow through the HVAC system or unusual fan noise. Regular replacement helps maintain optimal air quality and protects downstream HVAC components.
