FilterKeeper - 58mm Portafilter Paper Filter Holder
58mm FilterKeeper for Portafilter filters
A similar design to the popular FilterKeeper designed for the Aeropress. Many people have discovered that by placing a 58mm paper filter at the bottom of their portafilter, it allows for a more even extraction and easier cleanup. Store your 58mm portafilter paper filters within arms reach! Filters not included. I get my 58mm filters from Good Brothers Coffee. You can find a link under PortaKeeper Friends.
