Replacement filter cap with pressure valve and metal filter for AeroPress. Eliminates inverted method, allows oils through for fuller body. Requires AeroPress Original or Go.
Replacement filter cap with pressure valve and metal filter. $25-35. Best espresso-style upgrade for AeroPress owners. Eliminates inverted method, allows oils through for fuller body. Requires existing AeroPress Original or Go.
The Fellow Prismo is a replacement filter cap that bolts onto the Original or Go and adds two things: a pressure-actuated valve that holds liquid in the chamber until you press, and a 0.2 mm stainless metal filter that passes more coffee oils than paper. The valve eliminates the inverted method — you can brew upright with any recipe — and the metal filter pushes the body closer to espresso or French press territory. With very fine grind and firm pressing you can pull a thicker, more concentrated shot than standard AeroPress allows, though it's not true 9-bar espresso. At $25-35 it's an accessory, not a standalone brewer, and only worth the cost if you already own an AeroPress.
Pros
- Pressure-actuated valve removes the need for inverted brewing
- Metal filter retains oils for a fuller-bodied cup
- Enables espresso-style concentrate from an AeroPress
- Drop-in replacement — no new brewer required
Cons
- Accessory only — needs an existing AeroPress Original or Go
