Take your Aeropress brewing capabilities to the next level with Prismo, a pressure-actuated valve that allows a build-up of pressure to brew espresso-style coffee and creates a no-drip seal for recipes that normally require inverting your AeroPress. Plus, you no longer need paper filters since the Prismo comes with a reusable 150 micron filter. We love having the ability to brew espresso-style coffee, conveniently, from anywhere.
