SAI P70 Perfect Paper Filters
100pk of nice, thick filters to pair with a Saint Anthony Industries C70 or Phoenix70 pour over cone. The combination makes for a longer, higher % solubles extraction for a given grind size versus, say, the classic Hario V60 (all fine devices!)
These filters are clean, too: no powder/residue and no paper taste in your cup. You don't need to pre-rinse.
