What is Catapass and EPA Verification

Cat-A-Pass™ is a supplemental catalytic converter which reduces emissions of CO, VOC & NOx by 75% in highway driving. For economically disadvantaged communities whose members cannot afford to purchase EVs, regardless of federal tax incentives, Cat-A-Pass™ is a tool that can enable these communities to enjoy cleaner air with a low-cost supplemental catalytic converter. The primary pollutant that we target is NOx, because NOx leads to the formation of PM2.5 material, and because NOx is also a respiratory irritant.

Cat-A-Pass™ is designed for gasoline vehicles; it does not replace original catalytic converters. It is installed behind the original converters and further reduces the engines pollutants.

Cat-A-Pass™ is effective and durable. It has been aged to simulate 70,000 miles of use. Testing shows it reduces VOC, CO, and NOx by up to 75% when first installed, and it reduces NOx emission by 75% after 70,000 miles of use. Reducing these pollutants reduces the formation of both ozone and secondary PM2.5, which are the most immediately harmful pollutants.

EPA Review and Acceptance

The EPA conducts a voluntary testing program of after-market products such as Cat-A-Pass™. The EPA does not approve, certify, or endorse any products.

Both the EPA and the NJ Dept of Transportation tested and verified the first generation Cat-A-Pass design several years ago.

In the current version, the EPA has reviewed and accepted the performance testing data which shows that for at least 70,000 miles, Cat-A-Pass™ achieves average reductions of 45% each of CO and VOC and 75% of NOx.
