【0.8mm Thickness】The 0.8mm thick espresso puck screen 54mm does not require you to consciously reduce the amount of coffee. It allows you to maintain the ideal amount of coffee effortlessly. 【Keeping Clean】The puck screen effectively separates the coffee grounds from the brewing head and prevents coffee grounds from accumulating. This means you can enjoy your coffee without spending a lot of time and energy maintaining and cleaning the brew head. 【Double Structure】The 54 mm puck screen is equipped with a double structure. One layer has a small hole size of 0.3mm, while the other layer has a large hole size of 1.8mm. When inserting the puck into the portafilter, make sure the large hole is facing upwards so that the hot water is distributed more quickly into the coffee and extraction efficiency is improved. 【Stable Extraction】The pore distribution of the espresso filter screen is uniform and can effectively reduce channeling. This improves the overall uniformity of extraction. You can expect a stable and delicious coffee. 【High Quality Material】The espresso screen 54mm is made of food-grade 304 stainless steel, which ensures quality and durability and provides you with a high-quality coffee experience for a long time.
