If you make drip coffee at home, you know the moment of panic that sets in when you realize you forgot to buy filters. Save some trees, save some money, and eliminate possible barriers to caffeine with these organic cotton muslin “socks”. After each use, compost your coffee grounds, rinse the filter, and hang it up to dry. Every so often, boil them to get rid of oil buildup, and continue making great coffee! Just be sure to order the correct size for your dripper.
