Prismo is a pressure actuated valve designed to be used with the AeroPress® Coffee Maker. This attachment allows for a buildup of pressure to create espresso-style coffee and creates a no drip seal for a full immersion brew. The reusable 70 micron etched filter stops sludge in its tracks and eliminates the need for paper filters. The valve’s small aperture also fits directly over an espresso shot glass.
Please do not brew with Prismo over thin glass vessels. Prismo creates a great deal of pressure, and glass is fragile!
