Place a coffee filter inside the dripper, ensuring that the filter's bottom is in direct contact with the Booster.
Rinse the filter thoroughly, making sure the bottom of the filter remains in contact with the Booster. This step helps to eliminate any residual paper taste and prepares the filter for brewing.

Add your desired amount of coffee grounds to the filter.
Begin the brewing process, following your preferred brewing method or technique.
The Booster enhances the flow and extraction of your coffee, contributing to a smoother and more efficient brewing experience.
Allow the brewing set up to cool down to room temperature.
Remove the filter and the Booster from your dripper. Ensure that you have located the Booster, which may be attached to the dripper's bottom or stitched to the paper filter.
Rinse both the filter and the Booster thoroughly with hot water.
Following these steps will help keep your brewing equipment clean and ready for your next coffee brewing session.

Thanks to a fully sealed flat-bed structure decreasing the chance of bypass, the Flat 2 M filters enhances evenness and repeatability, ensuring greater precision in every brew
Seamless "plug-and-play" design, improving user experience and workflow efficiency
FAST Technology for Optimal Flow
Powered by FAST Specialty Coffee Filter technology, the FLAT 2 achieves an even and fast drawdown without the need for air channels, ensuring smooth, controlled extractions every time.
Materials & Packaging
FAST Specialty Coffee Filter paper technology
100% organic, crafted in Barcelona
Sealed packaging for freshness, protecting against dust and odors
Sustainable FSC-certified paper packaging
Engineered for baristas, competition brewers, and coffee enthusiasts, the FLAT 2 redefines consistency, efficiency, and precision in coffee brewing.

The selection of materials and Sibarist's manufacturing process are focused on achieving the highest possible quality over any other factor, while always respecting process sustainability.
The FAST line is composed of a mixture of abaca fiber from plantations in Ecuador and the Philippines (where the product consumed is replanted every year to then be harvested, offering a sustainable process, with batch control and chain of custody), cellulose fiber from European pine plantations (FSC and PEFC) and organic plant-based (non-fossil) polylactic acid.
The main component, abaca fiber, is finer and more porous than other fibers, giving FAST paper good permeability (leading to a higher extraction speed), while offering great tensile and tearing strength in wet conditions, bringing structure and resistance to the composition, with a low substance (less paper). Additionally, the fibers are pulp made from non-wood fibers. This facilitates clean in-plant processing, essential for eliminating the presence of external flavors in the cup and for offering a high-quality filter, while it can also be processed in a more sustainable way.
