How long will the Bosch HEPA cabin filter last and when should I replace it?

Bosch recommends replacing cabin air filters at least once every 12 months or every 12,000 miles, depending on driving conditions. Heavy pollution, dusty roads, or frequent city driving may require earlier replacement to maintain performance.

• No added chemical odor neutralizer—delivers unaltered filtered air
• Removes particulates that can carry odors, improving perceived freshness
• Compatible with standard HVAC systems; avoids introducing new fragrances
