• Bosch Activated Charcoal Workshop Cabin Air Filters feature a multi-layer media that offers a 99 percent efficiency rate at 3 microns or greater in keeping dirt and other particles from entering vehicle heating and air vents
• 1st Layer - Non-woven pre-filter layer captures larger particles
• 2nd Layer - Electrostatically charged microfiber layer attracts and holds elusive smaller particles
• 3rd & 4th Layers - Non-woven cover layers add stability to protect the microfiber layer from damage and act as an additional barrier to harmful elements
• 5th Layer - Activated charcoal layer absorbs toxic and foul-smelling gases such as ozone, nitrogen oxide, sulfur dioxide and hydrocarbons which results in fresher smelling air and reduced windshield hazing
