Flat Bottom Brew Gear Collection

Be the first ones to get the B3 FLAT Specialty Coffee Filter!

The B3 FLAT Specialty Coffee Filter utilizes the B3 Specialty Coffee Filter paper technology, jointly developed by Sibarist and 2021 World Brewers Cup Champion Matt Winton. This FLAT filter is for flat bed drippers (Kalita 185 style).

The B3 FLAT filter shape provides a brewing bed that promotes even extraction of the coffee particles, high uniformity turbulence and full access to the coffee bed. The B3 rigidness produce a minimum contact surface with the dripper and provides a fast extraction, but its material thickness and low porosity provides sweeter and clean cups, lowering bypass during the brewing process.

Sibarist packaging are made using composable materials.

B3 Flat filters are packaged in a flat stack with pre-folded creases for users to fold.

FILTER PREPARATION

1. Fold the 4 edges of the filter, following the indentation marks on the paper.When folding, it is fine to go over the folds, with no need to avoid the center area of the filter.
   
2. Place the filter on top of the dripper and gently push the edges of the filter with both hands to fold inwards
   
3. Starting from the center, gently and slowly rinse the filter with hot water by moving towards the outer edge in circular motion, while making sure that the entire surface of the filter is stuck to the walls of the dripper, without leaving any air channels between the filter and the filter holder.

Manufactured with care in Barcelona.

Engineered for those who refuse to compromise on what's in the cup.

HIFLUX 155 & 185 Wave Filters 60 sheets pack

Brewing great coffee is a science. The HIFLUX Wave Filter was designed with that in mind, and every element of its construction serves a specific, measurable purpose in how your coffee extracts, feels, and tastes.

Complexity, by design.

When water ponds above the coffee bed, the concentration gradient between water and coffee begins to equalize, slowing diffusion and limiting extraction efficiency. HIFLUX's high flow rate keeps fresh water moving through the bed continuously, maintaining a steep gradient and allowing extraction to work at full capacity. The result is complete, even extraction, even with a finer grind and in less time. Positive flavor compounds come forward while negative ones are suppressed. What you get is a cup with a noticeably more layered, complex flavor profile.

Body and texture you can feel.

The lyocell weave in every HIFLUX filter is precisely engineered to allow micro-particles under 20 micrometers to pass through. That is not a flaw. It is intentional. Those particles are what give coffee its texture and weight. The outcome is a silky, velvety mouthfeel that you would not typically expect from a pour-over, even in lighter roasts. That body also brings balance to the overall cup, rounding out acidity and brightness without muting them.

Flavor clarity that lasts.

This is where material choice matters most. Lyocell is a regenerated cellulose fiber, extruded into smooth, continuous threads rather than the wood pulp construction of traditional paper filters. That structural difference means significantly less surface area for lipid adhesion, allowing more oils to pass through. Since lipids carry aromatic compounds, the brew retains more aroma, more intensity, and more lasting flavor expression. The cup does not flatten after the first sip. It stays alive in the glass.

Available in 155 and 185 sizes to fit your existing dripper setup.

The new ORIGAMI Wave (Flat Bottom) Filter Box comes in two sizes, and each consist of 50 sheets of Wave filters

New Wave Style Filter by ORIGAMI
The new ORIGAMI wave-type paper filter is specifically crafted to pair with the ORIGAMI dripper. The ORIGAMI mix filter box features a unique wave design that perfectly matches the dripper's 20 ribs. By ensuring a snug fit, the filter minimizes gaps between the dripper and the paper, preventing water from bypassing the coffee grounds and optimizing extraction. This results in a more intense flavor profile, even during shorter brewing times.

The wave filter promotes a stable water flow, ensuring that water moves consistently through the coffee grounds. This balanced extraction process highlights the coffee's natural sweetness and body, without the risk of an over-extracted or bitter taste. Because the wave design creates a thinner coffee bed compared to traditional conical filters, water passes through more quickly, leading to even extraction from the top to the bottom of the grounds for a clean, balanced cup.

Crafted from natural pulp, the filter is designed to preserve the integrity of your brew, ensuring that no paper taste interferes with the coffee's nuanced flavors. The production process is meticulous, with filters pressed in small batches to reduce inconsistencies like wrinkles or folds. This attention to detail ensures a perfect fit with the ORIGAMI dripper, minimizing uneven extraction and allowing the coffee's true character to shine through.

Baristas across the globe have shared overwhelmingly positive feedback on the new wave filter, praising its ability to elevate the coffee’s natural flavors and aromas. Combining thoughtful design with exceptional materials, ORIGAMI’s wave filter offers an elevated brewing experience for those who appreciate the subtleties in their coffee.

The ORIGAMI Wave Filter Box are available in two difference sizes. The small 02 filter fits with ORIGAMI S drippers and medium 04 filter fits with ORIGAMI M drippers.
