The Moccamaster #4 filter paper is our filter of choice for use with your moccamaster, these are high-quality (chlorine-free) bleached filters that won't impart a paper flavour on your brew. 

We recommend rinsing them with water in your filter cone prior to putting coffee in them, this helps the filter keep its shape and position within the cone as well as remove and excess paper fibers that may be present. Happy brewing.
