Sales of diesel particulate filters for trucks and buses in California increased at the end of 2013 and in the first half of this year compared with the first half of 2013, according to a survey released Aug. 5 by the Manufacturers of Emission Controls Association.

The increase in sales in the second half of 2013 likely reflects the increase in activity by vehicles owners to meet the Jan. 1, 2014, compliance date under the California Air Resources Board’s truck and bus regulation, MECA said.

The continued higher sales in the first half of 2014 likely reflects CARB’s recognition of good-faith efforts made by vehicle owners  allowed to install DPFs through July 1.

The total number of verified DPFs sold by MECA member companies for in-use, on-road, heavy-duty diesel vehicles operating in California in the first half of 2014 increased to 5,780, a 65% increase over the 3,508 DPFs sold the same period in 2013 and on par with the 5,457 DPFs sold in the second half of 2013.

The CARB regulatory changes should provide lower-cost pathways for small fleets, low-mileage fleets and fleets that operate in nitrogen oxides attainment areas, MECA Executive Director Joseph Kubsh said.
