Granular carbon on open-cell PU foam. The highest carbon load we make, and the only media in our range with a measured ammonia figure — which matters, because cat urine odor is ammonia.

Why this one for ammonia
Cat urine odor is ammonia — a small polar molecule that plain activated carbon holds comparatively poorly. Fecal odor is mercaptans, where carbon is strong. A litter box makes both, which is why the construction matters more than the carbon grade.
It carries several times the carbon of a bonded-powder media at the same thickness, and the open cells let air pass through rather than around, so resistance stays low. Pore grade is selectable coarse, medium or fine to trade resistance against contact time. Granular media can shed — inside a pet enclosure it ships cloth-wrapped.

Where it is used
Chosen when the housing has depth to give and the duty includes ammonia — typically deodorizer cartridges.
Buyer questions
Frequently asked questions
Short answers drawn from the specifications on this page.
What is granular activated carbon mesh?
It is granular activated carbon bonded into open-cell polyurethane foam. It carries the highest carbon load we make: carbon content ≥80% and 1200 g/m² at 5 mm, in thicknesses from 3 to 50 mm.
Does granular activated carbon mesh remove ammonia?
It is the one media in our range with a measured ammonia figure: ≥20% by weight on a static saturated-vapor test, with the report available on request. That figure ranks the material; it is not a removal efficiency or a service life.
How do I choose the pore grade?
Pore grade runs from 15 to 60 ppi. Coarse pores give lower resistance and shorter contact time; fine pores give the opposite. As a reference, pressure drop is ≤100 Pa at 0.5 m/s for a 10 mm sheet.
Does granular carbon mesh shed carbon?
Granular media can shed. Where that matters, for example inside a pet product, we supply it cloth-wrapped.
