The Only Filter Designed for 3-Cup Chemex & Funnex - Unfold Your Perfect Brew The Chemex FP-2 Half Moon Filter is the specialized filter designed exclusively for the compact 3-cup Chemex and the unique Funnex brewer. Due to their smaller size and unique design, these filters arrive unfolded as flat half-moon circles that you fold yourself before brewing. Don't worry—folding is easy! Each box includes clear folding instructions, and once you've done it a few times, it becomes second nature. Many brewers actually prefer the ritual of folding their own filters as part of the mindful brewing process. These white, oxygen-cleansed filters are 20-30% thicker than standard coffee filters, delivering the same laboratory-grade filtration that Chemex is famous for—removing oils, fats, bitterness, and sediment for crystal-clear, full-bodied coffee.

Due to the unique half-moon shape and compact size of 3-cup and Funnex filters, they cannot be pre-folded. The half-moon design requires a specific folding technique that's incompatible with machine pre-folding. Why Half Moon Filters? Designed Specifically for Compact Chemex Brewers Unique Shape for Unique Brewers The half-moon circular shape is engineered specifically for the proportions of 3-cup Chemex and Funnex brewers. It's not just a smaller version of standard filters—it's a completely different design optimized for compact brewing. The 3-Cup Difference 3-cup Chemex brewers (and the Funnex) have different proportions than larger models. The half-moon shape ensures: Perfect fit in the smaller opening Proper cone formation when folded Optimal water flow for small batch brewing Correct 3-layer positioning against the spout Why They're Unfolded The half-moon shape and small size make machine pre-folding impossible. But that's actually a feature: You control the exact fold each time More compact storage Part of the mindful brewing ritual Easy to fold once you know how (5 seconds!)
