Carus manufactures a series of manganese-based catalysts, called CARULITE® catalysts. These Hopcalite® type catalysts (manganese dioxide/copper oxide) are used for breathable air purification, emission air purification, and process air purification.

Specific applications would include the destruction of carbon monoxide, ozone, and ethylene oxide as well as the adsorption of certain compounds and odors. CARULITE® catalysts are available in granular form in various sizes and in powder form for ozone removal applications. One unique aspect of CARULITE® catalysts is in its ability to destroy ozone and carbon monoxide at room temperatures, when used with recommended operating conditions.
