What maintenance is required for DPFs?
Diesel particulate filters need to be disassembled and cleaned approximately once per year. This can be done with compressed air or by heating the filter in a special filter cleaning device. The estimated to cost clean a filter by a dealer is in the range of $300-350. In addition, several manufacturers sell filter cleaning devices. Check with your engine dealer or diesel particulate filter vendor regarding particulate filter maintenance costs for your area. The Clean Buses for Kids Program does not pay for maintenance costs.
