Tired of constantly buying #4 filters? Sick of throwing them away? Using soft, organic cotton, this #4 size filter is hand-sewn in the USA. It fits on any #4 size cone (including the Clever Dripper), and comes in a pack of two - so you've always got a spare. We love the difference this filter makes. Not only are you reusing your filter, you're also creating a totally different flavour profile than you would get with paper or metal filters. Cloth filters allow more oils through, and therefore give you more body - without sacrificing complexity.
