The Prismo is a pressure-controlled valve designed for use with the AeroPress® coffee machine, allowing you to brew delicious espresso-style coffee in your Aeropress.
The Fellow Prismo consists of 2 parts, a valve and a metal filter. The metal filter will make your coffee richer in oils and because it is reusable, it also eliminates the need for paper filters.
The Prismo attachment is compatible with the AeroPress dimensions, so you simply fit it in place of your existing strainer, insert your coffee and simply squeeze.
