They are made from 3 layers of high grade stainless steel screen which consists of two outer support screens and one fine mesh screen in the center. The bottom ring of the filter is made from high quality heat and gas tolerant flexible silicone. Combined with our patented lip lock and technology your filters will stay on securely to your stacks.
