Combining filtration materials by lamination offers several advantages: enhanced efficiency, extended service intervals, and reduced energy consumption of filtration units.
June 21, 2025 - Ahlstrom has started-up a new state-of-the-art production line for molecular filtration media at its Turin site in Italy.
Molecular filter media are used in complement, removing gaseous pollutants, including volatile organic compounds, inorganic gases (such as sulfur dioxide, nitrogen oxides, ammonia), and odors, and delivering the cleanest air to people and processes.
According to Ahlstrom, the new production line offers a high degree of customization and design flexibility. "It enables precise tuning of adsorptive performance through detailed control of adsorbent types, blends, and content levels. The investment is complemented by a molecular filtration test bench to better support filtration manufacturers in developing high-performance filtration solutions," Ahlstrom said in a press release.
"The investment complements the existing Ahlstrom Trinitex® Carbon platform by targeting the growing demand for premium molecular applications such as cabin and fuel cell air intake filtration, as well as HVAC and cleanroom," the company added.
First announced in 2024, the project supports Ahlstrom's strategy to develop next-generation filtration solutions that purify air and liquid, and protect people, processes, and the environment.
"This new asset reflects our ambition to drive innovation in filtration and takes our molecular filtration expertise to the next level,", says Giuseppe Costa, Vice President, Global Filtration. "By expanding our capabilities, we are ensuring that our customers continue to receive the reliable, high-quality solutions they expect from us."
Ahlstrom is a global leader in combining fibers into sustainable specialty materials.?Its three divisions include: Filtration and Life Sciences, Food and Consumer Packaging, and Protective Materials along with Performance Materials cluster.
