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.

How it brews

The reusable stainless disc that replaces the paper micro-filter in an AeroPress cap — the same part is sold as the Gold-Tone, and an XL version covers the larger brewer. Because it's a metal mesh rather than paper, it lets more oils and some fines through, so brewers tend to get a fuller, more textured body and more sediment in the cup than the clean paper finish. It's a one-buy, washable option with no ongoing paper cost. AeroPress publishes no flow rating and there's no reliable within-seat ranking against the paper disc, so we leave flow unrated rather than guess.
