Stage 4 Filters – Prep Pro

The Odorkleen 250 filter offers superior performance in gaseous and odor adsorption, as well as excellent particulate filtration. This “combination” product contains 250gsm of carbon product attached to a high efficiency cotton-polyester media blend of granular activated carbon and activated alumina impregnated with potassium permanganate. The Gas-Phase Filtration Media “CarbonWeb”® technology are efficient, carbon filled media fibers that provide low resistance and high capacity. Its gas phase, 60% activity granular activated carbon has nearly five million square feet of surface area per pound. Either alone or in combination, the media fibers are filled with odor control granular activated carbon and other types of absorbents for gaseous pollutants. The result is high-efficiency filtration for a variety of challenges.

Unlike many competitors’ products, the "flexible carbon filled media" bonds between the fiber in the OdorKleen 250 and only uses approximately 1% of the carbon’s surface area. This maximizes the exposure of the gas contaminant to the carbon. The 3/8" light/medium duty media layer used to capture the particulate contaminants is made up of a cotton-polyester blend that has carbon filled fibers. The combination of the two distinct medias give this filter an efficiency rating of MERV 8, while maintaining a low pressure drop... unlike our competitors’ products!
