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.
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.
