  • 22/9 Stock update: The 155 boxed pack of 50 and 185 bagged pack of 100 filters are currently out of stock. We have replacement stock on the way from Japan, however delays to international container shipping linked to the conflict in the Middle East have pushed back the expected arrival date. We still have limited stock of the 155 bagged pack of 100 filters and good availability of the 185 boxed pack of 50 filters. Thanks for your patience while the shipment makes its way to us.

    If you're brewing on a flat-bottom dripper, the Kalita Wave is probably your paper. Designed specifically for Kalita's flat-bottom brewers, these are one 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 consistently produce clean, balanced cups with the kind of repeatability that makes dialling in a lot less painful.

    The key is the 20-wave construction. Those crimped edges keep the paper off the dripper walls, creating small air pockets that help hold brewing temperature and keep water moving evenly through the coffee bed. Pair that with a flat-bottom design and you've got a setup that's properly forgiving: less channelling, more consistency, without giving up any clarity in the cup.

    They're made in Japan from oxygen-bleached, FSC-certified pulp: flavour-neutral, responsibly sourced, and compostable after use. We're the UK importer for Kalita. Pair them with a Kalita Wave dripper, or check our pour-over brew guides if you want to get more from every brew.

  • Do I need to rinse Kalita Wave filters before brewing?
    It's optional, but worth doing. The paper is thin and doesn't add much papery taste anyway. The bigger wins are preheating your dripper and helping the filter sit properly in the brewer. Both make for a more consistent extraction.
    What's the difference between the 155 and 185 sizes?
    The 155 is built for single brews of around 200–300ml. The 185 handles larger pours of 300–500ml. Go by how much you typically brew in one go rather than the number of cups you're planning to fill.
    Can I use Kalita Wave filters in other drippers?
    Yes. The 185 fits the Orea V3 and V4, Origami Dripper (M size), April Brewer, Fellow Stagg [X], and most other flat-bottom brewers that take 185-size papers. The 155 works with the Torch Mountain Dripper, Origami Dripper (S size), and similar smaller flat-bottom brewers. Check your dripper's recommended paper size before ordering if you're not sure.
    What's the difference between boxed (50) and bagged (100)?
    The filters are identical. It's purely about packaging and quantity. The boxed version comes in a rigid box of 50, which keeps everything flat and protected. The bagged version gives you 100 in a resealable bag, so better value if you brew regularly. Both sizes come in 155 and 185.
    Can I buy Kalita Wave filters in bulk?
    Yes. Contact our wholesale team at wholesale@ozonecoffee.mom for trade pricing.
    Are Kalita Wave filters environmentally friendly?
    Yes. They're made from oxygen-bleached, FSC-certified pulp. That means the paper comes from responsibly managed forests and is free from chlorine. Once you're done brewing, the filter and spent grounds can go straight into your compost bin together.
    Are Kalita Wave filters compostable?
    Yes. They're plain paper, oxygen-bleached rather than chlorine-treated, so they can go straight into your compost bin along with the spent grounds after brewing.
    Where can I buy Kalita Wave filters in the UK?
    Directly from us, online. As the UK importer, we keep stock of both 155 and 185 sizes for home brewers and wholesale customers alike.
