Zeolite is a natural mined mineral. This highly porous granular mineral does not dissolve in water or other inorganic solvents. Clinoptilolite zeolite, the type of zeolite found in our zeolite products, effectively absorbs ions and molecules. Zeolites are know as molecular sieves, meaning that they selectively absorb molecules on the basis of shape, size or electrical charge. As a result, zeolite quickly absorbs liquids and eliminates odors in minutes. Zeolites (particularly clinoptilolite) are often added to animal feed and function much the same as food grade diatomaceous earth. Zeolite is also known to work as an insecticide.
