Sibarist Fast Flat Specialty Coffee Paper Filter

FLAT is a high-performance flatbed filter designed with FAST or B3 Specialty Coffee Filter technology to enhance extraction and flavor clarity.

The FLAT is an original, non-fluted flat-bottomed filter designed and registered by SIBARIST. Its smooth and unobstructed surface ensures a perfectly even brewing space with full access to the coffee bed. This design eliminates the bypass effect, maximizing coffee particle yield while preventing grounds from getting trapped in fluted areas.

FLAT S for small flatbed drippers (e.g., Kalita 155)  
FLAT M for standard flatbed drippers (e.g., Kalita 185)
