STAINLESS STEEL BAFFLE FILTERS About Your New Filters Stainless Steel Baffle Filters do not need linings or mesh inside of the filters and are completely constructed out of stainless steel. The stainless steel construction allows them to be used again after being cleaned or going through the dishwasher. How do Baffle Filters Work?
