Bosch Activated Charcoal Filters can trap close to 100% of airborne contaminants and foul-smelling gases and odors.
Bosch Premium Cabin 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 Activated Charcoal Filters go one step further than Particulate Filters. Bosch Activated Charcoal 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.
Cabin filters are generally found in one of three locations: under the hood, inside the glove box or under the dashboard. Recommended replacement is every 12,000 to 15,000 miles, or once a year.
