Superpowers for your Aeropress; courtesy of the clever crew at Fellow Products.
The Prismo is a reusable 80 micron (perfect size) filter housed in a pressure actuated valve assembly. You can brew a bit stronger of a coffee, similar to a Moka Pot, or use this as a normal Aeropress filter. The valve eliminates dripping while brewing, which has always been one of the drawbacks of the Aeropress.
We've already thrown one of these in our travel kit, and recommend you do as well!
