Chemex White Filters (FS-100)
These are specifically designed for Chemex brewers, these fit all Chemex models except the small 3 Cup size. We really recommend Chemex filters for your brewer, and the Chemex type (pre-folded squares) are only pennies more than standard filters. I like the square pre-folded best because they are strong, and when it comes time to toss the filter (into your compost, of course!) they do not fall apart. The square type give you neat handholds on the corner.
