Our History

Car-Mon Products, Inc. has been a leader in the carbon monoxide industry for over 60 years. The first known underfloor system to be used specifically for the removal of vehicle exhaust was designed by Cornell Imming of O.A. Wendt Company, a Chicago heating and vent contractor, in 1943. This was for a new prototype Cadillac dealership that was to occupy the first two floors of a multi story building.
