Prismo is a pressure-actuated valve designed to be used with the AeroPress Coffee Maker. This attachment allows for a buildup of pressure to brew espresso-style coffee and creates a no-drip seal for recipes that normally require inverting your AeroPress. Eliminate the need for paper filters, a reusable 150 micron etched filter stops sludge in its tracks and fits directly over your favorite espresso glass to “pull a shot” at home. Espresso-style, full-immersion, cold brew, hot/iced tea, americanos, and more—endless recipes are just one plunge away! We at Fellow love coffee and are obsessed with product design. Fellow believes you should never have to choose between aesthetics and functionality when handcrafting a brew. Whether you're a coffee aficionado or a beginner, we believe everyone should have fun with the craft of brewing.
