NO SMOKE 2 is designed for any 2007/2010 or newer vehicle with an After Treatment Device

The NO SMOKE 2 diesel filtering system differs from the NO SMOKE as it does not require the diverter box technology. The system is constantly filtering harmful exhaust from the environment inside the fire station at cold starts, and while low idling on scene.

 The NO SMOKE 2 system is installed in the tailpipe before the tip and well after the ATD. We do not touch anything with the ATD or the diffuser tip so that we do not void the manufacturer’s warranty. 


The filter is constructed of a flow thru substrate with platinum, palladium and other compounds that allow the system to regenerate when the manufacturers' ATD regenerates. Virtually alleviating the need to change the filter. 

The system provides protection when it is needed most, during periods of low temperature exhaust – cold starts, low idle and on-scene use. It is at these times the manufacturers' ATD is not actively oxidizing emissions. It takes 40 to 60 minutes for the vehicle to come to temperature before allowing the ATD to begin oxidization. The NO SMOKE 2 is always on and protecting.
