The S Filter is the most popular reusable filter for AeroPress coffee makers. It's protected by Kaffeologie's unique UNCONDITIONAL LIFETIME GUARANTEE: you can return or exchange your S Filter ANY time, for ANY reason - no matter what. The S Filter is the only reusable filter for AeroPress guaranteed not to bend or warp during normal use, so it's sturdy enough to permanently replace your paper filters.

The S Filter is also the finest reusable coffee filter in the world: it has holes just 41 microns across, so the S Filter traps grit other reusable filters can't catch. The S Filter's mesh keeps grit OUT while keeping flavor IN: it's an ultra fine design that traps virtually all grit while brewing coffee that tastes especially rich and clean (paper filters absorb those rich flavor oils, which is why many S Filter customers and reviewers say S Filter coffee tastes better). Cleanup is easy: grit washes off the S Filter's mesh in seconds (it's dishwasher safe too).

The S Filter is proudly MADE IN THE USA with 316 stainless steel, a special grade of steel that's extremely resistant to corrosion. Quality materials mean the S Filter can be slim enough to fit perfectly (.017" or about the thickness of paper) and still incredibly strong: it's the only reusable filter guaranteed not to break - even years from now.
