The MHW-3BOMBER FG5591M-OS is a 54mm double-layer espresso puck screen made from 304 stainless steel. With 8911 mesh and 0.18 mm filtration precision, it distributes flow evenly to improve extraction while helping keep the brew head clean. At 0.8 mm thick, it’s thinner than typical screens, reducing the need to adjust dose. Compatible with 54mm portafilter baskets, including Breville/Sage; not recommended for machines with an internal screw in the brew head. Hand wash; not dishwasher safe.
