All CoffeeSock® Filters out-perform any comparable disposable and reusable filters. These filters are made with certified organic cotton and are expected to last about a year before quality of brew begins to fade. They are 10-50% the cost of disposable filters per year, and 20% the cost of quality reusable filters. Cotton is a more efficiently renewable resource than plastic, metal, or paper.

Initially, boil new filters in fresh water to clean and shrink for 10 minutes. Periodically, once every 4-6 weeks boil filters in fresh water to remove accumulated coffee oils. If the filters are soiled with perishable food at anytime, boil for at least 5 minutes to sanitize.
