There are large deposits of volcanic zeolite minerals found in the western United States.
Natural zeolites have a unique interconnecting lattice structure.
This lattice structure is arranged to form a honeycomb framework of consistent diameter interconnecting channels and pores. Negatively charged alumina and neutrally charged silica tetrahedra building blocks are stacked to produce the open three dimensional honeycomb framework. The active ingredient in the Eco Fresh product line is natural volcanic zeolite. Natural zeolites are formed from the altered volcanic ash. The material can encompass and control many times its weight in odors or moisture.
