An extraordinary add-on to the Aeropress, the Fellow Prismo is a combination reusable metal filter and pressure-actuated valve. At a glance, the Prismo seems firmly positioned as a tool for users looking to create espresso-like beverages at home. While it can certainly help on that front, it also provides experienced Aeropress users with a versatile attachment that can work in combination with standard paper Aeropress filters to eliminate the need for potentially-messy inverted recipes.

Requires an Aeropress, available here.
