IMS Precision Filter B702TCH28.5E – Competition Filter for Perfect Espresso
Professional extraction for your bottomless portafilter
With the IMS Competition precision filter basket B702TCH28.5E, you get the most out of your espresso beans. This high-quality filter basket from the renowned Competition series by the Italian manufacturer IMS noticeably improves extraction and ensures more consistent results in your cup.
Why the IMS B702TCH28.5E?
What makes this precision filter basket special is its cylindrical shape with a convex base (the "C" in the name stands for "Convex"). This ingenious design directs the coffee precisely to the center during extraction and is specifically designed for bottomless portafilters. You get a focused, central stream – ideal for impressive bottomless shots.
The 715 round holes with a conical cross-section in a hexagonal pattern are a patented IMS innovation. They ensure significantly better crema formation and a more even flow through the entire coffee puck – right to the edge.
