Potassium Permanganate for Gas & Odor Removal

Potassium permanganate filter media is an adsorbent substrate, typically activated carbon, impregnated with potassium permanganate. Rather than only holding contaminants on a surface, it oxidizes them — chemically breaking down gases and odors into less harmful compounds.

Potassium permanganate media targets hydrogen sulfide, sulfur compounds, odor-causing gases, certain VOCs, reactive chemical vapors, and industrial emissions. It is especially effective on compounds that activated carbon alone captures less readily.

Potassium permanganate media is commonly used in odor control systems, air purification equipment, specialty HVAC filtration, industrial ventilation, chemical filtration, environmental control systems, and gas-phase contaminant removal.

Activated carbon captures contaminants by adsorption, holding them on its internal pore surface. Potassium permanganate media works by oxidation, chemically converting contaminants into less harmful compounds. Because the two mechanisms target different contaminants, the media are often used together in the same filtration system.

No. The oxidation reaction consumes the potassium permanganate, so the media is replaced on a schedule rather than regenerated. Service life depends on contaminant type and concentration, contact time, and system design.

Yes. Potassium permanganate media can be supplied in different substrates, thicknesses, sizes, and converted formats depending on application requirements.

Gremarco impregnates AWWA-grade potassium permanganate at 97% minimum purity onto carbon and other porous substrates, applied under controlled conditions for even distribution across the media. Because oxidation depends on consistent contact between the contaminant and the active chemical, uniform impregnation directly affects performance. Combined with multiple substrate options, custom formats, and in-house converting, this lets us match the media precisely to your application.
