Same concept as puck screen, with improved water flow distribution from the shower head and enhanced espresso extraction. Helps keep the coffee machine's shower head cleaner. Each 58mm espresso filter paper is made from natural virgin pulp and is chlorine-free. Crafted from high-quality, carefully selected wood materials. Unlike stainless steel puck screens, these paper filters eliminate the need to remove and clean metal components from used coffee grounds. The paper filter is gentler on the machine compared to stainless steel, helping to protect the espresso machine and extend its lifespan. Designed to fit 58mm portafilters, compatible with various models including E61, Flair 58, ECM, Rocket, Sanremo, Synesso, Slayer, VBM, and others.
