The Kalita Wave implements a chopped-cone shape with a flat bottom. At the bottom of the wave drippers (Ceramic and Stainless) there are three triangulated holes that are connected by a raised edge that helps keep the filter from suctioning flush against the bottom. The Wave filters create a wedge against the edge of the dripper helping promote temperature stability.

The design of the Kalita Wave leaves a lot more margin for error than other pour over brewers as the flat-bottom does not necessitate as careful of a pouring technique. As with other pour over brewing methods the Kalita is quick (2-4 minutes) and easy to clean up.
