How it brews The larger (2-4 cup) Wave paper — same crinkled flat-bottom cup as the 155, scaled up for the 185 dripper. The flat bed and three small drain holes hold the coffee off the walls and reward a steady, unfussy pour, which is why the Wave is a go-to when you want repeatability over a cone's higher ceiling. Kalita doesn't publish a flow class and there's no dependable within-seat ranking, so flow is left unrated here rather than invented. The 185 seat is widely shared: OREA Wave, the larger Stagg (XF) and Blue Bottle papers all drop into it. 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.)
