The K-Filter – KYMIRA Nanofibre Replacement Filters

The filter that makes the K-Mask what it is. The KYMIRA Nanofibre K-Filter is independently tested to ASTM F2100, ASTM FT101, and EN 1486 standards — 99.6% filtration efficiency, effective for 200 hours, protecting against particles as small as 0.03 microns.

A triple-layer nanofibre construction: electrostatic capture on the outer layers traps viruses, bacteria, and pollutants; an activated carbon middle layer handles environmental particulates. The biocompatible hydrophobic material is elastic, electrostatic, and won't become wet with water vapour — reducing carbon dioxide re-breathing. Filters can be cut to size without damaging the technology, making them compatible with any mask with a filter pocket. Available individually or in 5-packs (17% saving).
