Fast Filtration & Full Flavor: Made from premium imported Canadian wood pulp, our filters deliver faster flow than standard filters. This advanced design helps prevent coffee grounds from building up or burning, reducing the risk of sour or bitter tastes. The paper absorbs oils and removes sediment while allowing rich, full-bodied flavor to pass through. Coffee stays hot after filtration. Health & Safety: Our small coffee filters are oxygen bleached, avoiding the use of chlorine and harsh chemicals, leaving no chemical taste, supporting a clean and enjoyable coffee experience. They are fully biodegradable and FSC certified, benefiting both health and the environment. Wide Compatibility: With an unfolded diameter of 15.5cm and a bottom diameter of 4.3cm, our filters are designed to fit Kalita Wave 155 drippers and compatible with a variety of drip and pour-over coffee makers, flat bottom drippers, small coffee makers, single serve coffee makers, and grind and brew single cup coffee makers. These filters also work well as #2 cone filters, ideal for 1-2 servings. Convenient and Easy to Use: Our mini coffee filters feature wavy edges for even water distribution and sturdy sides that resist collapsing, simplifying the brewing process. The flat bottom promotes consistent coffee extraction for a balanced cup. Disposable and easy to handle, they help keep the brewing area clean. Beginner & Profriendly: Suitable for all skill levels, these filters are easy to use and deliver consistent results. Unlike cone filters that may require precise grinding and pouring, the flat-bottom design maintains an even coffee bed for uniform water flow, making brewing easier for beginners and reliable for experienced users. Ideal for use at home, in the office, or while traveling. Note: Measurements are taken manually; please allow for a 1-3cm variation.
