We do not publish an adsorption capacity figure for zeolite media. Capacity depends on the grade, the loading, humidity and contact time, and we would rather send you material to test than quote a number we cannot stand behind. Free sample, one time; shipping is not included.

Why zeolite rather than carbon
Activated carbon works mainly by physical adsorption in nonpolar pores. Zeolite's aluminosilicate framework carries a charge, and that charge — not pore volume — is what gives it affinity for small polar molecules such as ammonia.
It is a different job, not a better one. Zeolite is weak exactly where carbon is strong: mercaptans, solvents and mixed VOCs. Choosing it instead of carbon rather than alongside it usually makes a product worse. Because the zeolite sits on a polyester base it cuts, folds and die-cuts the way filter cotton does, without cracking. Our granular carbon media is the one product where an ammonia figure is measured and a report is available.

Where it is used
Most demand sits in water — aquarium and pond filtration, and water-treatment stages where ammonium is the target.
Buyer questions
Frequently asked questions
Short answers drawn from the specifications on this page.
Is zeolite better than activated carbon for odor?
It does a different job. Zeolite is a polar adsorbent with an affinity for ammonia and ammonium, where plain activated carbon is comparatively weak. It is weak where carbon is strong: mercaptans, solvents and mixed VOCs. It works best alongside carbon, not instead of it.
What forms does zeolite filter media come in?
Zeolite on a polyester nonwoven base, 1–20 mm thick, in two grades: beige fibrous natural and grey powdered. It is supplied by the roll, as filter cotton or as die-cut pads, and cuts and folds like filter cotton.
Do you publish an ammonia capacity for zeolite media?
No. Capacity depends on the grade, the loading, humidity and contact time, and we would rather send material to test than quote a number we cannot stand behind.
Is zeolite media used in water or in air?
Both. Most demand sits in water, in aquarium and pond filtration and water-treatment stages where ammonium is the target. In air it is used where ammonia is the problem, such as covered litter pans and pet filter pads.
