How it brews

The larger round paper disc cut for the AeroPress XL cap — a bigger seat than the standard AeroPress, so this filter and the standard one do not interchange in either direction. Like the smaller disc it works under a pressed column rather than a gravity drip, catching fines and oils so the pressed cup lands clean; the extra diameter simply matches the XL's wider chamber and larger batch. AeroPress states no flow class for it and there's no dependable within-seat ranking, so we leave flow unrated rather than invent one. Brewers who dislike any trace of paper tend to give it a rinse before brewing.

How it brews

A reusable organic-cotton pad cut to the AeroPress filter cap, from CoffeeSock. Cloth sits between paper and metal: the cotton absorbs some of the oils a metal disc would pass, yet lets the acids through, so the cup reads clear and crisp without the papery note of a fresh paper filter. It's washable, lasts about a year of daily use, and composts at the end of its life. No published within-seat flow rating, so we leave flow unrated.
