The Sibarist brand, which is known for its special filters and accessories even for the most demanding coffee grinders, comes with an edition of paper filters for drippers with a flat bottom.
FAST FLAT is a flat bottom filter made by FAST Specialty Coffee Filter technology. The filter offers a unique, smooth and uncovered surface that offers a perfect and even space to prepare your pour-over with full access to the coffee bed. It eliminates the bypass effect and ensures the most uniform extraction with maximum extraction of coffee beans, as it prevents the capture of coffee particles in the grooved areas.
Size M filters are only suitable for dippers with a flat bottom (e.g. Kalita 185)
