Based on more than 20 years of experience in catalytic filtration, Gore has developed GORE® DeNOx Catalytic Filter Bags that help achieve NOx and NH3 emission levels similar to an SCR, but at a much lower cost of ownership. The Gore technology combines an ePTFE membrane for particulate removal with a PTFE-based catalytic felt for simultaneous reduction of NOx and NH3.  Because the GORE Membrane effectively traps dirt and dust, it also protects the catalyst and extends its performance-life.
