Ceramic Particulate Filters

Corning® DuraTrap® filters offer monolithic design and advanced material compositions to optimize pressure drop, filtration efficiency, durability, and system cost. They are designed to trap soot, or particulate matter, from diesel or gasoline exhaust emissions in a variety of light-duty and heavy-duty applications. Alternate channels are plugged to force exhaust through the pores of cell walls, leaving behind soot particles that are too large.

Corning® DuraTrap® AT filters 
For proven perfomance in light-duty diesel systems
We’re supporting the drive to improve fuel efficiency in passenger cars and trucks with our light-duty aluminum titanate filters. Introduced in 2005, these filters have proven their performance and durability in millions of vehicles.

Corning® DuraTrap® AT LP filters 
For next-generation light-duty diesel systems
Corning® DuraTrap® AT LP filters are designed with a lower porosity and optimized microstructure, enabling product designs for low pressure drop or high soot mass limit.

Corning® DuraTrap® AT HP filters 
For higher wash coat loads, enabling integrated NOx solutions in light-duty diesel systems
Our high porosity filters enable low backpressure at high wash coat loads and excellent filtration efficiency under real-world driving conditions.

Corning® DuraTrap® GC filters 
For reduced particulate number emissions in light-duty gasoline systems
Corning's gasoline cordierite filters feature GDI-optimized compositions to meet filtration efficiency, wash coat loading, and pressure drop needs.

Corning® DuraTrap® AT filters 
For high durability in heavy-duty diesel systems
Our aluminum titanate filters offer a robust solution to meet tightening diesel emissions standards. They deliver excellent durability, high thermal capability and low back pressure.

Corning® DuraTrap® AC filters  
For excellent pressure drop benefits in heavy-duty diesel systems 
Corning’s advanced cordierite filters offer back pressure benefits while lowering overall system and operating costs.
