HIGH QUALITY MATERIAL: Our espresso ice ball sieve is made of 1.1mm thick stainless steel, which is flat enough to ensure quality and durability and provide you with long-lasting and high-quality coffee. Stable extraction: The 51mm paddle sieve has a flat surface and uniform pore size, which improves water distribution and reduces the risk of splashing. The fine holes and multi-layer sintering design promote the full extraction of coffee powder and enhance the aroma of coffee. KEEP CLEAN: The 51mm metal filter effectively separates coffee grounds from the group head, preventing the accumulation of coffee grounds. This means you can enjoy your coffee without spending a lot of time maintaining and cleaning the group head. Double-layer structure: Adopt a double-layer structure. One layer has 0.3mm small holes and the other layer has 1.8mm large holes. When inserting the disc into the filter holder, make sure the large hole is facing up to distribute hot water more quickly into the coffee and increase extraction efficiency. Versatile Use: Espresso filters can be used in a variety of environments: home, office, kitchen, restaurant, coffee shop, cake shop and many other places. This handle filter is an ideal gift for coffee lovers. NOTE: Please make sure the size is compatible with your coffee machine before purchasing.
