CoffeeSock filters are durable and may last a year or more. CoffeeSock filters are a reusable alternative to paper filters and nylon sacks. All of our filters out-perform any comparable disposable and reusable filters. CoffeeSock filters are made with Certified Organic Cotton. Cotton imparts no flavor on the finished brew unlike paper. Cotton is 90% cellulose, which is a tasteless and odorless compound that is insoluable in water. Wood is 40-50% while Hemp is approximately 45% cellulose. CS filters are made in Austin, Texas. All filters are sewn and packaged by happy human beings making a fair and living wage.
