Are you looking for an advanced and clean alternative to standard wave filters? The Sibarist FLAT filters are the original concept of a non-ribbed flat-bottom filter, designed and patented by Sibarist to offer a perfectly uniform brewing space.
Choose the technology you prefer: FAST (ultra-fast) or B3 (balanced), and turn your extraction into a precision performance.
✨ Innovation and Advantages (Unique Design)
The smooth and unobstructed design of FLAT is designed to improve every aspect of your flat-bottom extraction:
-
Smooth and Flat Surface (Original SIBARIST Design): The original non-fluted (grooveless) design ensures a perfectly uniform brewing space and full access to the coffee bed.
-
Eliminates Trapping: Prevents coffee particles from getting trapped in grooved areas, ensuring every gram of coffee is extracted evenly.
-
Zero-Bypass Effect: The structure maximizes contact between water and coffee, eliminating bypass effect and maximizing coffee particle yield.
-
Maximum Flexibility: Available in two technologies to suit your brewing style:
-
FAST: For very fast extractions and maximum clarity.
-
B3: For a more balanced extraction and a slightly fuller body.
-
📏 Perfect Compatibility
FLAT filters are compatible with the most common flat-bottom drippers, such as Kalita Wave, OREA V3, and others:
- FLAT S (Small): Ideal for small flat-bottom drippers (e.g., Kalita Wave 155, 1-2 cups).
-
FLAT M (Standard): Ideal for standard flat-bottom drippers (e.g., Kalita Wave 185, 2-4 cups).
🔬 Materials and Sustainability
