Made in the United States out of grade-316 stainless steel, the Aeropress reusable filter weighs about 13 grams and features an array of holes that are each 178 microns wide, which the company said is small enough for effective filtration but wide enough not to hinder flow or add resistance when pressing.
The company said it chose 316 steel for its improved anti-corrosion and chemical resistance properties as compared to grade-304 steel, another popular material found in the field of reusable coffee filtration.
“We’ve offered paper filters since the Aeropress Original debuted, and Aeropress users have enjoyed them for the clarity of the brew they produce. But people also love getting creative with brewing variables to make a cup exactly how they like it, and different filter types allow for lots of experimentation,” Constance Romero, marketing associate at Aeropress, told Daily Coffee News. “Overall, if clarity is important to you in your cup, we suggest our paper filters. But if you’d like a little more body in your coffee, or simply want the convenience and/or sustainability benefits of a reusable filter, give our new stainless steel filter a try.”
