Envirofill artificial turf infill is a non-toxic, antimicrobial, eco-friendly, impact absorbing, and completely reusable synthetic turf infill material made up of naturally occurring silica sand from the USA. With Envirofill, you can be confident that your children and pets are safe in your artificial lawn. The outdoor elements are no match for Envirofill infill, with its compression resistant round quartz core, patented coating, and Microban® antimicrobial technology infused into the artificial grass infill material during the manufacturing process. Envirofill infill locks out moisture from the outdoor turf and will not absorb water or pet waste and will help prevent the growth of mold, mildew, and bacteria that can cause odors, stains and product deterioration.
