TrafficMaster Envirofill artificial grass/turf infill is pet and dog friendly, people friendly and environmentally friendly. At its core, Envirofill is a round grain of sand coated with acrylic. The acrylic coating encapsulates the sand completely, creating a virtually dust-free product. This coating is infused with Microban which prevents the growth of bacteria and microbes that can cause stains, odors, and product deterioration. This especially helps when your pup does his business on your lawn as Envirofill will be proactively preventing those microbes from producing those pesky urine odors. Envirofill is the lowest maintenance infill for any artificial turf system. Its round shape was designed to resist compaction while its high-bulk density helps it stay in place. That means it wont float, migrate, or fly away, so you wont have to continue to add more infill, plus its round shape helps ensure proper drainage. Its rich green color makes for an artificial turf surface that's more lush-looking and green for longer and Envirofill is 100% non-toxic. Its been put to numerous tests and has passed with flying colors. Thousands of homes across America breathe easy knowing their beloved kids and pets are safe running and playing on turf installed with Envirofill. The grass really is greener with Envirofill, with its winning combination of cleanliness, low maintenance upkeep, attractive appearance, and durability. Regular silica sand infill simply is no match.
