Bosch Premium Carbon Activated Cabin Air Filters absorb up to 100% of all pollen, dust particles and harmful substances. This results in a noticeable improvement in the air quality inside the vehicle. Bosch Carbon Activated Cabin Air Filters go one step further than Particulate Filters. Bosch Carbon Activated Cabin Air Filters have a 5-layer design that includes an additional carbon layer that absorbs toxic and foul-smelling gases such as ozone, nitrogen oxide, sulfur dioxide and hydrocarbons, and an additional cover layer for extra protection.
- 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
