20 Waves, Flat Bottom, 3 Holes
The namesake feature of the Wave Seriesis that the contact surface between the filter and
the inner dripper has 20 waves is on the side, and is not in contact with the flat bottom.
Due to the limited contact surfaces, hot water does not accumulate when poured but rather consistently drips to the Wave Zone.
The Wave Zone is created by the flat bottom allowing uniform flow. With 3 holes the water will not accumulate.
