Fits all Van Ness enclosed litter pans.

Only the pure ness air filter offers a real solution - zeolite, a nature mineral which actually removes ammonia odors from the air. In our patented system of air purification, zeolite-coated filter pads soak up ammonia gas on contact. Enjoy true odor control with the pure ness air filter, the nature ammonia remover that absorbs urine odor before it leaves the litter box.
