Compost pail filters are made of carbon coated nylon. They help to ensure an odor-free environment. Replace both filters every 4-6 months (or sooner if you think the odors are not contained enough, or you are frequently emptying the contents of the pail).
Remove filters before washing any of our compost pails. This contains 2 filter sets for the Jumbo Stainless Steel Compost Pail.
