This charcoal activated Cab Fresh filter features the Dual Filter System, which removes 97% of all diesel soot, dust, and dirt. It also reduces odors by 76%, leaving you with a cleaner, more habitable cab. A clean filter will help reduce road grime, pollen, and clogging of your fans and air conditioning system.


This charcoal-infused filter fits older Peterbilt trucks. We also carry a chrome cover - see Related Items.
