Designed specifically for Kalita's flat-bottom brewers, these are some of the most trusted filter papers in specialty coffee, used in cafés and home setups the world over. They come in two sizes (155 and 185) and produce clean, balanced cups with the kind of repeatability that makes dialling in a lot less painful.\u003c\/p\u003e\n\u003cp\u003eThe 20-wave construction keeps much of the paper away from the dripper walls, creating space for water to flow evenly through the coffee bed. Combined with Kalita's flat-bottom, three-hole design, this makes for a forgiving brewing setup that's straightforward to use and easy to get consistent results from.\u003c\/p\u003e\n\u003cp\u003eThey're made in Japan from oxygen-bleached, FSC-certified pulp and are compostable after use. We're the UK importer for Kalita, so you can get both 155 and 185 filters directly from us.\u003c\/p\u003e\n\u003ch3\u003eWhich Kalita Wave filter size do I need?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e155:\u003c\/strong\u003e Generally a great choice for single brews of around 200–250ml.

The 185 can also be used for smaller 200–250ml brews, but its larger brewing area creates a wider, shallower coffee bed, which can affect how the coffee brews.\u003c\/p\u003e\n\u003cp\u003eThe 155 and 185 refer to the approximate diameter of the Wave filter paper when it is laid flat, in millimetres. Make sure you match the filter size to your brewer: 155 filters for 155 brewers and 185 filters for 185 brewers.\u003c\/p\u003e\n\u003ch3\u003eHow to brew with Kalita Wave filters\u003c\/h3\u003e\n\u003cp\u003eOur simple Wave recipes use the same basic pouring pattern for both sizes, scaled up for a larger brew.
