Say goodbye to gritty coffee with these premium percolator filters! This 100-pack of 3.5-inch disc filters fits most standard percolators including popular models like Bozeman, Butte, and Scoutmaster. The 10mm center hole is the normative size that works with most camping coffee pots and home percolators. What makes these special? They're made from medical-grade fiber that maintains its integrity during brewing - no more torn filters leaving grounds in your coffee. They actually help reduce cholesterol too by filtering out coffee bean oils that can raise your levels over time. Each filter weighs just 1 gram but they're tough enough to handle the boiling water in percolators without breaking down like paper filters sometimes do. The story behind COLETTI is pretty cool too - founded by veterans with a mission to support religious freedom worldwide, with 10% of profits going toward that cause. So you're not just getting better coffee, you're supporting a good mission too. Whether you're camping, making coffee at home, or just tired of drinking grounds with your brew, these filters make a noticeable difference in your coffee quality. Pack of 100 means you're set for months of great-tasting, grit-free coffee!
