Fast Filtration & Full Flavor: Made from premium imported Canadian wood pulp, our filters deliver 30% 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 residue or taste. They are fully biodegradable and FSC certified, supporting both personal health and environmental sustainability. Wide Compatibility: With an unfolded diameter of 15.5 cm and a bottom diameter of 4.3 cm, these 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. They also function well as #2 cone filters, ideal for 1-2 cup brewing. Convenient and Easy to Use: Featuring wavy edges for even water distribution and reinforced sides that resist collapsing, these mini coffee filters simplify the brewing process. The flat bottom promotes consistent coffee extraction for a balanced cup. Disposable and easy to handle, they help keep your workspace clean. Beginner & Profriendly: Suitable for all skill levels, these filters offer reliable performance. Unlike cone filters that require precise grinding and pouring, the flat-bottom design maintains an even coffee bed for consistent results. Ideal for use at home, in the office, or while traveling.
