Zeolite Max is an odor controlling pet deodorizer that contains non-toxic, biodegradable granules that trap and neutralize ammonia-based odors by direct contact or air. Zeolite Max is the only infill of its kind to carry a negatively charged ion – creating the critical variable that prevents ammonia from turning into a gas, thus eliminating any unpleasant smell or odor. Zeolite Max is primarily used as a supplemental infill, which is placed under the turf as well as the base of the fibers to manage odor control. We recommend pairing Zeolite Max with Envirofill for the best results.
