- Fast filtration and full flavor: Crafted from imported Canadian wood pulp, our filters deliver 30% faster flow-through than standard filters. This design prevents grounds from pooling and burning, reducing sour or bitter notes. The paper absorbs oils and removes gritty sediments while letting a rich, full-bodied flavor come through. The coffee stays hot after filtration. - Health and environment: Oxygen-bleached to eliminate chlorine and harsh chemicals, these filters do not leave chemical tastes, ensuring a healthy and enjoyable coffee experience. They are fully biodegradable and FSC certified, protecting both your health and the environment. - Wide compatibility: Unfolded diameter 6.1 inches, bottom diameter 1.7 inches. Compatible with Kalita Wave 155 drippers, and fit a wide range of drip and pour-over brewers, flat bottom drippers, small coffee makers, single-serve coffee pots, and grind-and-brew single cup makers. They also perform well as #2 cone filters for 1-2 people. - Convenient design: Wavy edges promote even water flow, with sturdy sides that wont collapse. Flat bottom design enhances extraction for a balanced cup. Disposable and easy to replace, they simplify the brewing process and keep your prep area tidy.
