Bosch P3915WS Workshop Particulate Cabin Air Filter

The Bosch P3915WS Workshop Cabin Air Filter is engineered to deliver cleaner, healthier air to your vehicle's interior. This advanced multi-layer filter offers a 99 percent efficiency rate at 3 microns or greater, effectively capturing dirt, dust, pollen, and other harmful environmental particles before they enter your HVAC system.

Advanced Three-Layer Filtration System:

• Non-woven pre-filter layer captures larger particles
• Electrostatically charged microfiber layer attracts and holds elusive smaller particles
• Non-woven cover layers add stability to protect the microfiber layer from damage and acts as an additional barrier to harmful elements

Key Features:

• High pleat count provides greater surface area for higher filtration capacity
• Foam perimeter gasket or rigid frame included where specified by OE
• Constructed from durable polyester filter material
• Designed and tested to meet High Efficiency Particulate Air (HEPA) standards based on test standard ASTM D2986

Cabin air filters are designed to clean the air that enters your vehicle through your car's heating, ventilation and air-conditioning (HVAC) system. Cabin filters should be inspected at least once a year, with more frequent replacement recommended for vehicles driven in heavy traffic or dusty conditions. Signs that replacement is needed include reduced airflow through your HVAC system or unusual noise from the blower fan.
