Cabin Filter (Activated Charcoal) – VW/Audi / Mk5 / Mk6

Bosch Workshop Cabin Air Filters are specifically engineered for the professional installer dedicated to helping customers breathe cleaner air. Bosch Workshop Cabin Filters offer an 80% efficiency rate at 3 microns or greater in capturing dirt, dust and other environmental contaminants from entering the heating and air vents of a vehicle.

• Mold-resistant multi-layer media maximizes performance and durability
• 1st Layer – Non-woven pre-filter layer captures larger contaminant particles
• 2nd Layer – Electrostatically charged microfiber layer attracts and holds elusive smaller particles
• 3rd & 4th Layers – Non-woven cover layers adds stability to protect the microfiber layer from damage and acts as an additional barrier to harmful contaminants
• 5th Layer – Activated charcoal layer absorbs toxic and foul-smelling gases such as ozone, nitrogen oxide, sulfur dioxide and hydrocarbons
• More pleats provide greater surface area for higher filtration capacity
• Foam perimeter gasket (where specified by OE) prevents harmful particles from bypassing the filter media
• Injection-molded frame (where specified by OE) adds stability for peak performance and long service life
