How it brews

OREA's wave paper is a 185×185 mm Japanese-stock wave filter. OREA states it's "compatible with any brewer that works with the Kalita Wave 185 filters, as this shape and size is the same" — fitting the V3, V3 MK2, Glass OPEN and V4 Narrow/Wide (not the Big Boy) — so it sits in the Kalita Wave 185 seat and interchanges with those papers. OREA publishes no bleach or flow spec, so both are left blank rather than guessed. (OREA also makes a flat "Type G" paper, catalogued separately.)

How it brews

Origami's wave-shaped paper for its drippers, a cellulose sheet in S (155) and M (185) sizes — the flat-bottom, crinkled-wall cup that fits the Kalita-Wave seat rather than a cone. It stands the bed on the fluted paper away from the walls the way Wave papers do, and it interchanges with Kalita-Wave 155/185 papers of the matching size. Origami publishes no fast/medium/slow class for it, so flow is left unrated. (Origami also sells a conical paper for the same dripper — this is the wave one.)
