Greenfiltec posts first-half loss as activated carbon costs squeeze margins

Greenfiltec reported first-half 2026 consolidated revenue of NT$311 million, up 18.35% from a year earlier, but the Taiwan-based airborne molecular contamination (AMC) filter supplier swung to a net loss of NT$140 million. The company said higher shipments of high-end filters for semiconductor customers lifted sales, while surging activated carbon costs cut into profitability.
