In addition, the Puck Screen will reduce the need for cleaning of the brew head, as it will minimize the amount of coffee material that is pulled into the brew head when lifting the lever after a shot is completed. The Puck Screen will prevent the need to remove the brew head, perhaps to once a month or less, as it will trap the material within the mesh which can be easily flushed out under the tap.

Given the thermal mass of the screen, it is recommended that it is placed in the portafilter and locked in just before turning on the preheat controller.
