Even Water. Cleaner Extraction. Every Shot. A puck screen sits on top of the coffee puck inside the portafilter basket, between the grounds and the grouphead shower screen. When the grouphead engages, water passes through the puck screen before hitting the puck — distributing pressure evenly across the entire puck surface rather than letting it concentrate in one area. The result is reduced channeling, more even extraction, and a cleaner grouphead shower screen after each shot. Available in Single, Double, and Triple Layer, in 51mm, 54mm, and 58mm. From $12.90. Single vs Double vs Triple Layer — Which One Do You Need? Single Layer — one stainless steel mesh screen. Entry-level upgrade from no screen at all. Improves water distribution and keeps the shower screen cleaner between backflushes. Best for: home brewers who want a simple, low-maintenance improvement. Double Layer — two stainless steel mesh layers. Greater flow resistance distributes water pressure more evenly across the puck surface, reducing channeling more effectively than a single layer. Best for: baristas who are actively dialling in extraction consistency. Triple Layer — three stainless steel mesh layers. Maximum flow resistance and the most even water distribution of the three options. Particularly effective with lighter roasts and finer grinds where channeling risk is highest. Best for: specialty coffee setups where extraction evenness is the primary focus. Choose Your Size 51mm — DeLonghi ECP series, EC155/221, ECO310, Dedica EC680/685/785/820/850/860 54mm — Breville / Sage Barista Express, Barista Pro, Barista Touch, Bambino, Bambino Plus, Infuser, Duo Temp Pro 58mm — E61 groupheads (Rocket, ECM, Rancilio, Profitec, Lelit, Flair 58), La Marzocco, Gaggia, Nuova Simonelli, and more Features 304 stainless steel — food-grade, corrosion-resistant, reusable. Built for daily use without degrading. Even water dispersion — distributes grouphead pressure evenly across the puck surface to reduce channeling and improve extraction uniformity. Keeps the shower screen cleaner — the puck screen catches fine grounds before they reach the grouphead shower screen, extending the time between deep cleans. Reusable, no paper filters — rinse after each shot. Clean with Cafiza or steam if stained. Safe for years of daily use. Easy to use — place on top of the tamped puck before locking in the portafilter. Remove and rinse after the shot. Perfect For Pairing with a WDT tool, distributor, and tamper for a complete puck prep sequence. Anyone using light roasts or fine grinds where uneven extraction is most noticeable. Extending time between grouphead backflushes by catching fine grounds before they reach the shower screen.
