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

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.

Crafted in Korea from European pulp material, HIFLUX is the next-generation paper filter integrates advanced lyocell fiber technology with a precision 3D weaving structure to redefine brewing clarity and control. Its unique micro-pattern regulates the movement of fines, allowing a controlled amount of ultra-fines to pass through therefore enhancing mouthfeel while maintaining a clean, balanced cup.

Engineered for performance, the HIFLUX lyocell technology filter achieves a flow rate up to 42% faster than conventional paper filters, unlocking finer grind settings, higher extractions, and shorter brew times with consistency.

Made from FDA-compliant, 100% chemical- and plastic-free materials, the HIFLUX lyocell technology Filter is clean tasting, with no added paper smell or flavor, ensuring the purest expression of your coffee. Thoughtfully designed and proudly made in Korea, the HIFLUX filter linesets a new benchmark for sustainable, precision brewing.

Also available in Cone Small and Cone Medium.

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
