A portafilter basket is the metal filter cup that holds your coffee grounds, and its hole pattern affects how evenly water passes through the puck. Swapping a stock basket for a precision one can make shots more consistent.
The six baskets below come from well-known suppliers and cover 54mm and 58mm sizes. We have not used these products ourselves, so confirm the exact size, dose and fit for your portafilter on the current listing before you buy. Everything here is general guidance only.
