HIFLUX - The World’s First Lyocell Technology Coffee Filter

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.

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.

Rethink about your "Paper Bed"

This Lyocell technology allows a 3 dimensional paper bed to be structured - allowing a 3-dimensional flow. 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.

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 manufactured to allow micro-particles under 20 micrometers to pass through, giving coffee its texture and weight. The outcome is a silky, velvety mouthfeel that you would not typically expect from a pour-over, bringing balance to the overall cup, rounding out acidity and brightness without muting them.

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 line sets a new benchmark for sustainable, precision brewing.

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