Reusable coffee filter for richer flavor
Cores Gold Filter coffee filter KF4 is an exclusive, reusable option for those who want to get more flavor from every brew. This coffee filter works excellently for hand brewers with filters and replaces traditional 1x4 filters without muting the coffee's natural oils. The result is a richer cup, less waste, and a brewing experience that feels both thoughtful and practical. We especially like that it is easy to bring to work, the summer house, or trips where you want to brew really good coffee without disposable filters.

Care instructions
Rinse the filter with water immediately after use. Hand washing is also recommended to keep the filter in good condition over time. Since this is a metal filter, a small amount of coffee grounds may end up in the cup, but this does not affect the quality of the brew. Place the filter on the included holder or in a dripper when in use. If you use it in a coffee machine, you should follow the machine's instructions, as the fit may vary between different models.
About the manufacturer
Cores is a Japanese coffee brand focused on letting the coffee shine. Their Gold Filter series is developed to highlight flavor and coffee oils, while making brewing easier and more resource-efficient without disposable filters. We appreciate the combination of thoughtful design, low Weight, and clear function. One thing to know is that a bit more sediment may come through into the cup than with paper filters, so this filter is best for those who prioritize flavor depth over completely clear brewing.
For those who want to brew with more flavor, less waste, and a premium feel in every cup, this is a thoughtful choice for the daily coffee moment.
