Fast Filtration & Full Flavor: Made from premium imported Canadian wood pulp, our filters deliver 30% faster flow than standard filters. This advanced design ensures that coffee grounds don't build up or burn, preventing sour or bitter tastes. Our paper absorbs oils and removes gritty sediment while allowing a rich, full-bodied flavor to pass through. Coffee stays hot even after filtration. Health & Safety: Our small coffee filters are oxygen bleached to eliminate the use of chlorine and harsh chemicals, leaving no chemical taste, ensuring a healthy and enjoyable coffee experience. They are fully biodegradable and FSC certified, protecting both your health and the environment. Wide Compatibility: With an unfolded diameter of 15.5cm and a bottom diameter of 4.3cm, our filters are perfectly compatible with Kalita Wave 155 drippers, and fit a wide range of drip and pour-over coffee makers, flat bottom drippers, small coffee makers, single serve coffee makers, grind and brew single cup coffee makers. Our versatile filters also perform exceptionally well as #2 cone filters, perfect for 1-2 people. Convenient and Easy to Use: Our mini coffee filters feature wavy edges for even water flow and sturdy sides that won't collapse, making brewing a breeze. The flat bottom further enhances coffee extraction, delivering a perfect cup every time. Disposable and easy to clean, they simplify the brewing process and keep your coffee preparation area clean.
