Best and Worst Turf Infill Options for Pet Urine and Odor Control
This article is all about turf infill and the true factual information that surrounds it. Infill plays a major role in how artificial turf reacts to pet urine and why ammonia smells form extremely fast in many turf systems. Not all infills are created for pets, and many commonly used options fail almost immediately once exposed to repeated urine.
Using and tested with ammonia readers, observed how different infills respond to urine over time and how quickly ammonia odors develop. Based on real world performance, we have ranked these infills from the worst to the best so homeowners can understand what actually works and what does not.
What Is Turf Infill and Why It Matters
Turf infill is the granular material installed between artificial grass blades after the turf is laid down. While it may look like simple sand or grit, infill plays a critical role in how turf performs and how long it lasts.
Infill helps turf blades stand upright, adds weight so the turf stays in place, protects the backing from sun damage, supports drainage, and absorbs impact from foot traffic and pets.
Without proper infill, artificial turf mats down quickly, shifts, overheats, and wears out prematurely.
For pet turf, infill is even more important.
Why Pet Turf Smells Like Ammonia
When a dog urinates on artificial turf, the liquid drains through the turf fibers and settles into the infill layer. That infill becomes the first material to interact with the urine.
As urine sits in the turf system, bacteria begin breaking it down. This process creates ammonia gas, which is responsible for the sharp sour smell many pet owners experience.
If the infill cannot manage urine correctly, the turf will smell no matter how often it is rinsed or sprayed.
This is why choosing the correct infill is more important than any surface deodorizer.
#6 – Silica Sand
The Worst Turf Infill for Pets
Silica sand is the most commonly used turf infill and the worst option for pet environments.
Silica sand was never designed for odor control. It does not neutralize urine, kill bacteria, or reduce ammonia. It does not even claim to.
Its only purpose is weight and blade support.
When dogs urinate on turf filled with silica sand, the urine drains into the sand and stays there. Moisture builds up, bacteria multiply, and ammonia forms rapidly.
Ammonia readings on silica infill rise quickly and remain high even after rinsing or deodorizing.
Silica sand provides zero odor protection short term or long term.
Silica sand showed extreme readings of 100.00
#5 – Envirofill and Wonderfill
Pet Marketed Infills That Fail Quickly
Envirofill and Wonderfill are very similar mineral based infills often marketed as pet friendly.
These infills rely on absorbing odor rather than eliminating it. Initially, this can appear effective. Over time, they become saturated with urine and stop working.
Once saturated, odor releases back into the air and ammonia readings rise rapidly.
Cleaning provides only temporary relief because the source of the odor remains trapped inside the infill.
They may perform slightly better than silica sand early on, but long term results are poor.
Envirofill & Wonderfill showed extreme readings of 98.7
#4 – OptiFill
Odor Issues Plus Tracking Problems
OptiFill is often presented as a premium pet infill, but real world performance shows consistent odor issues over time.
Like CamoFill, OptiFill slows odor development initially but still allows ammonia buildup as urine exposure continues.
Ammonia readings rise steadily, and turf odor returns despite maintenance.
OptiFill also introduces an additional problem. Because it is color treated, the dye can sometimes transfer from the infill granules. This material can track into homes on shoes or dog paws, leaving residue on flooring and entry areas.
This adds extra cleanup and frustration beyond odor issues.

#3 – Zeolite Based Infills
Absorbs Odor but Does Not Eliminate It
Zeolite based infills are often considered an upgrade from basic infills because they absorb ammonia odors well at first.
Turf with zeolite frequently smells fine when new.
The problem is saturation.
Once the pores fill with urine and ammonia, zeolite stops working. It does not neutralize ammonia or stop bacterial growth.
When saturation occurs, ammonia readings rise quickly and odors return suddenly. In multi dog homes or warm climates, this can happen fast.
Zeolite also requires ongoing treatment to prevent unhealthy bacterial buildup.
Zeolite showed extreme readings of 72.6
#2 – CamoFill
Longer Lasting but Still Smells Over Time
CamoFill performs better than zeolite and delays odor longer. It represents a step forward in infill technology.
Ammonia readings rise more slowly, and turf stays usable for a longer period.
However, CamoFill still relies on suppressing odor rather than destroying it. Over time, repeated urine exposure overwhelms the material and pet odors return.
Camofill showed extreme readings of 99.8
#1 – Infill X
Best Turf Infill for Pets Short Term and Long Term
Infill X operates in a completely different category than every infill above.
It is designed to eliminate odor at the source rather than absorb or mask it.
Infill X activates when moisture touches it. When urine enters the turf system, the infill immediately begins neutralizing ammonia and interrupting bacterial activity.
Ammonia testing consistently shows zero readings.
This performance holds immediately after installation and long term under repeated urine exposure.
Infill X does not go through a saturation phase where it suddenly fails weeks or months later.
Infill X showed clean and normal readings of 2.8
Self Deodorizing and Rechargeable Turf Infill
Like all materials, Infill X has a usable lifespan.
The difference is how it is maintained.
Instead of being removed and replaced, Infill X can be recharged through professional treatment and restored to near new performance.
This eliminates infill tear out, excavation, and replacement costs while maintaining long term odor control.

Turf Infill Ammonia Reading Results
Using common ammonia scale ranges:
• 0–10 → clean / normal
• 10–25 → noticeable contamination
• 25–50 → strong urine presence
• 50+ → severe saturation
• 90+ → extreme buildup
Proof of Ammonia Readers Testing Turf Infill
Pet turf odor problems are almost always infill problems.
Surface sprays and enzymes may help temporarily, but they cannot fix the wrong infill underneath.
If your turf smells, it is not your dog. It is the infill.
Choosing the correct turf infill from the start is the difference between a yard that smells in weeks and one that stays fresh for years.
