Van Ness Replacement Zeolite Filters

Zeolite-coated replacement filter cartridges for our Large, Extra-Giant, and Sifting Enclosed Litter Pans. Zeolite, a natural mineral, effectively removes ammonia odors from the air--absorbing them before they leave the litter box. Effective for up to three months. Fits the Van Ness CP-6, CP-7 (requires 2 cartridges), and CP-66 enclosed cat pans.
