We've tested a lot of filters out in our time. We love these as far as reusable filters go. Comparable in cup cleanliness to the best paper filters, the cotton absorbs some oils and all the grit while letting all those tasty acids through. No paper taste. No need to pre-rinse.
These filters are made with 100% GOTS Certified Organic cotton, made in the US, and are as eco-friendly as it gets. Brew, rinse, hang to dry. It's that easy.
We have the size 4 filters and the ones that fits most cone-shaped drippers, like a Hario V-60. 2 filters per package.
