Pack of 2 filters - CoffeeSock Reusable Coffee Filters - Basket 6-12 Cup (2 Filters) - Organic Natural Cotton Coffee Filters Made in the USA - Ultra-Durable 1 Year Filter Set - Eco-Friendly Compostable Cloth 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. Cotton absorbs some of the oils released from coffee beans yet lets acids pass through. CoffeeSock was started in 2011 to create a superior class of organic sustainable coffee filters that you can use guilt-free. Over the years we've tweaked and perfected our filters to last longer than any other and preserve even the most subtle flavors of the highest grades of gourmet coffee. We make all of our filters in the USA in Austin, Texas. Get the best for your home and for your life from CoffeeSock!
