Artificial Turf Infill Comparison (2026)

Infill is the material spread between artificial turf blades. It weighs down the turf, supports the blades, provides cushion, and affects drainage, temperature, smell, and safety. Choosing the right infill is as important as choosing the turf itself.

Complete Comparison Table

Silica Sand

The most common and cheapest infill. It is simply finely ground quartz sand, typically 16/30 or 20/40 mesh size.

• Pros: Cheap, heavy (holds turf down well), excellent drainage, widely available at hardware stores
• Cons: Gets very hot in sun (can reach 150°F+), zero odor control, can compact over time reducing drainage
• Best for: Budget installations, decorative areas with low foot traffic, no pets
• Application rate: 2-3 lbs per square foot

Zeolite

A natural volcanic mineral with a unique microporous structure that absorbs ammonia and other odor-causing compounds. The premium choice for pet owners.

• Pros: Best odor control of any infill (absorbs ammonia at molecular level), natural and non-toxic, lightweight, good drainage
• Cons: More expensive, lighter weight (may need nails for high-wind areas), needs annual top-up as it breaks down
• Best for: Dog areas, any installation where odor is a concern
• Application rate: 1.5-2.5 lbs per square foot

Crumb Rubber

Made from recycled tires. Common on sports fields but increasingly controversial for residential use.

• Pros: Cheapest infill available, excellent cushion (ideal for fall protection under play equipment), widely available
• Cons: Gets extremely hot (hottest of all infills), potential health concerns from chemicals in recycled tires, not safe for pets who dig/chew, black color absorbs maximum heat, can stain skin and clothing
• Best for: Sports fields only. Not recommended for residential use.
• Application rate: 3-5 lbs per square foot

Multiple studies have investigated whether crumb rubber is carcinogenic. Results are inconclusive, but the EPA and many states have recommended caution. Several cities and school districts have banned crumb rubber infill on public fields.

Envirofill (Acrylic-Coated Sand)

Silica sand coated with an acrylic antimicrobial layer. Marketed as a premium alternative to plain sand.

• Pros: Antimicrobial coating inhibits bacteria growth, cooler than plain sand, good odor control, 16-year warranty from manufacturer
• Cons: Most expensive common infill, coating can wear off over time, limited color options
• Best for: Premium residential installations, families with children and pets
• Application rate: 1.5-2 lbs per square foot

Organic Infill (Cork and Coconut)

Made from natural cork or coconut husk fibers. The coolest and most eco-friendly option.

• Pros: Coolest surface temperature of any infill (stays 15-20°F cooler than sand), 100% natural and biodegradable, naturally antimicrobial, pleasant appearance
• Cons: Breaks down faster than mineral infills (needs replacement every 3-5 years), can float out during heavy rain, lighter weight
• Best for: Hot climates, eco-conscious homeowners, barefoot areas
• Application rate: 1-2 lbs per square foot

Choosing the Right Infill: Decision Guide

• Have dogs? → Zeolite (odor control is non-negotiable)
• Have kids who play barefoot? → Organic cork/coconut (coolest, safest)
• On a tight budget? → Silica sand (cheapest, works fine without pets)
• Want the best overall? → Envirofill (antimicrobial, cool, long warranty)
• Hot climate? → Organic or Durafill (coolest options)
• Sports field? → TPE or crumb rubber (best cushion)

Infill Maintenance

Factor in ongoing infill costs when calculating total cost of ownership. Zeolite and organic infills need more frequent replacement but provide superior performance.
