Take your AeroPress brewing up a notch with the all new version of the Aesir filters! The original Aesir filters were developed as Eldric Kuzma was preparing for the 2016 Canadian AeroPress Championship. The result of extensive testing of a range of types of paper to find one that makes the best possible cup of coffee, these new filters have a small pore size that makes for a full-bodied cup with less sediment, giving you a noticeably cleaner and more vibrant coffee.
