Ready to up your coffee game? These reusable coffee filters are made with 100% organic unbleached linen and offer a solution to disposable or plastic basket filters. Cotton thread ensures a long life, and plastic free coffee experience. Use and care instructions: Before first use, we recommend boiling filters for 10 minutes to prepare them for your coffee ritual. To brew, place one reusable filter inside the coffee basket of your coffee machine, and fill with desired amount of ground coffee. Brew as desired. Empty grounds from filter after use, rinse and hang dry filter. You can store your filter(s) in water in the fridge, or freezer for prolonged freshness. Boil filters periodically to clean. For use in coffee machines that make 6-12 cups. Made by Marley's Monsters in Eugene, Or.
