Organic, natural and environmentally safe, ZeoLite is the best infill choice for pet areas. Made of 97% pure clinoptilolite, ZeoLite is the perfect infill for sports fields, residential and playground applications. Clinoptilolite zeolite is volcano ash that landed on water millions of years ago. It's not the most well known but widely used as a gas absorber, a food additive, a water filter from drinking water, and an odor control agent. ZeoLite is well suited for artificial grass applications due to its large amount of pore space, high resistance to extreme temperatures and chemically neutral basic structure.
