Zeolite for Air & Water Filtration
Gremarco provides zeolite filtration media for air purification, water treatment, odor control, and specialty filtration applications. Natural clinoptilolite captures ammonia, formaldehyde, VOCs, and other polar compounds that conventional media often miss — in both air streams and water systems.
Available in rolls, sheets, and custom-cut formats, with flexible substrate options and precision converting capabilities, Gremarco zeolite media supports a wide range of industrial, commercial, and engineered filtration solutions.
How Zeolite Filtration Works
Zeolites work through two mechanisms: adsorption, where contaminants adhere to the vast internal surface area, and cation exchange, where the crystal structure swaps its native ions for charged compounds in the stream. This second mechanism gives zeolite a strong affinity for ammonia and other polar molecules that carbon captures less readily.
1
Adsorption
Zeolite molecules capture pollutants by attracting and holding them to their surface. Unlike mechanical filtration, adsorption works at the molecular level, making zeolites effective against gases and odors that pass straight through standard particulate filters.
2
Contaminant Removal
Zeolites are particularly effective at adsorbing ammonia, formaldehyde, and a range of VOCs — some of the most problematic and persistent indoor air pollutants. As contaminants move through the media, these compounds are captured and held within the zeolite's porous structure.
3
Clean Output
Air or water exiting a zeolite filter is substantially reduced in targeted contaminants — ammonia, odors, and gaseous pollutants. The result is measurably improved quality in commercial, industrial, and aquaculture environments.
Applications of Zeolite
1
Odor and
Ammonia Control
Used where ammonia and organic odors concentrate: animal facilities, litter and waste handling, refuse areas, and refrigeration. Zeolite's ion exchange capacity makes it especially effective against ammonia, which many other media capture poorly.
2
Commercial & Industrial
Filtration
Used in HVAC systems in schools, hospitals, and manufacturing facilities to capture formaldehyde, VOCs, and chemical odors. Often paired with HEPA media so gases and fine particulates are addressed together.
3
Water Treatment and Aquaculture
Used to remove ammonia from aquaculture systems, ponds, and aquariums, where it accumulates quickly and is toxic to fish. Also captures heavy metals such as lead, copper, and zinc through cation exchange.

Application-specific material selection
Zeolite filtration is frequently used in combination with other air purification technologies to deliver comprehensive air treatment. When paired with HEPA filtration, zeolite media addresses the gas and odor spectrum while the HEPA layer handles fine particulates such as dust, pollen, and allergens — together covering a broad range of air quality challenges.
Selecting the right adsorbent media depends on the specific contaminants targeted, airflow conditions, and application requirements. Gremarco works with OEM manufacturers to identify the appropriate zeolite media format — whether roll stock or die-cut — and advises on replacement intervals to maintain consistent filtration performance.
