3piece coffee filter mesh set (51mm, 53mm, 58mm) crafted from foodcontact qualified stainless steel. Heat resistant and built for repeated use, it provides consistent performance for your daily espresso ritual while eliminating disposable filters. Key benefits Durable, reusable stainless steel construction that is foodcontact qualified and heat resistant. Reduces waste and ongoing filter costs by replacing paper filters with a reusable mesh. Enhanced extraction with a doublelayer filter screen that forces water to flow more evenly through grounds, dissolving more flavor compounds and reducing channeling for a richer, more balanced espresso and improved crema. Complete size compatibility with three standard sizes (51mm, 53mm, 58mm) to fit virtually any espresso machine, making it ideal for homes with multiple machines or cafes with diverse equipment. Improved water distribution thanks to an innovative mesh design that converts harsh water jets into a gentle, uniform flow across the coffee puck, preventing uneven extraction and bitter spots and creating the brewing environment for exceptional espresso quality. Practical use scenarios Home use with multiple machines: Switch between 51/53/58 mm baskets without changing gear, while cutting back on disposable filter waste. Small cafe or office: One set serves machines with different portafilter sizes, helping maintain consistency across equipment. Sustainable routine: disposable paper filters in daily brewing, reducing waste while preserving brewing performance.
