In as much as the Kalita Wave pour-over drippers are stylish and highly functional on their own, the Kalita Wave Filters are what gives the majority of its style and function!
These filters are designed to maintain a stable temperature by keeping itself suspended above the bottom of the dripper and by keeping water contact away from the walls of the dripper.
It is recommended to thoroughly rinse each dripper before use although, Kalita doesn’t think that this is necessary, by pouring hot water directly into the middle of the filter, until the water fills to the top, and let it drain back out.
