KNODOS 58mm Bottomless Portafilter is engineered for E61 group head espresso machines. The open-bottom construction removes the standard spouted housing, exposing the filter basket completely. This lets you watch the espresso extraction in real time, diagnose channelling and uneven flow, and make informed adjustments to grind size, distribution and tamping pressure. The stainless steel body is precision-machined to the E61 standard, ensuring a smooth lock-in at the group head with no wobble or leakage. The solid maple handle provides heat insulation and a natural, comfortable grip — it stays cool to the touch even after consecutive shots. Each portafilter ships with an 18–21g double shot filter basket featuring a precision hole pattern for even water distribution. The basket seat is compatible with IMS and VST aftermarket baskets, giving you room to upgrade without replacing the portafilter itself. Fits Rocket, Lelit (including Mara X and Bianca), ECM, Profitec, Ascaso, Quick Mill, Bezzera, Flair 58 and other machines built around the E61 group head. KNODOS espresso accessories are designed for home baristas who value both craftsmanship and performance. Combine this portafilter with our matching tampers, distributors and tamping stations for a coordinated, professional setup
