Fellow Prismo AeroPress Attachment

The Fellow Prismo is a pressure actuated brewing attachment designed to unlock new brewing possibilities for the AeroPress Coffee Maker. By building pressure during extraction, the Prismo allows you to brew rich, concentrated espresso style coffee without the need for an espresso machine. Its integrated no drip valve also enables full immersion brewing without inverting your AeroPress, making the brewing process cleaner, easier, and more consistent.

Unlike the standard AeroPress filter cap, the Prismo remains sealed until pressure is applied during pressing. This allows coffee to steep fully before extraction begins, improving consistency while giving users greater control over brew time. The result is a fuller bodied cup with enhanced texture and a concentrated coffee suitable for espresso style drinks, milk based beverages, iced coffee, cold brew recipes, and creative brewing experiments.

The Prismo includes a reusable 150 micron etched stainless steel filter that eliminates the need for disposable paper filters while allowing more natural coffee oils to pass through for increased body and mouthfeel. Constructed from durable polypropylene with a food grade silicone pressure valve, it is built for everyday brewing while remaining lightweight and highly portable.

Compatible with the AeroPress Original, AeroPress Clear, AeroPress Premium, AeroPress XL (with the appropriate model), and AeroPress Go Plus, the Fellow Prismo is not compatible with the AeroPress Go or AeroPress brewers manufactured between 2005 and 2009.

To care for your Fellow Prismo, simply remove the reusable metal filter after brewing and rinse thoroughly with warm water. Clean the silicone valve periodically to prevent coffee oil buildup and maintain smooth operation. Wash with mild detergent when necessary and avoid abrasive cleaning tools that may damage the filter or valve. Allow all components to dry completely before reassembly and storage.
