材料是過濾的起點

Material is where filtration begins. Working from the application, Oltaven defines fibre composition, basis weight, thickness and structure together with appliance and filter makers, then moves into sampling and validation. We do not build finished equipment; we focus on making the media well.

我們的工作圍繞材料本身展開：複合濾材、微纖維玻纖、熔噴與靜電材料、活性炭複合、膜與層壓材料，以及配套的支撐與骨架。交付形式可以是卷材、片材或按圖模切件。
