Air quality in enclosed environments such as buildings and vehicles is a growing concern worldwide.  While particulate filter media play a crucial role in removing solid particles and aerosols, molecular filtration media complement them by capturing gaseous pollutants—including volatile organic compounds, inorganic gases (such as sulfur dioxide, nitrogen oxides, ammonia), and odors—to deliver the cleanest air to people and processes.

Ahlstrom’s molecular filtration platform delivers high-performance media with exceptional design flexibility. It enables precise tuning of adsorptive performance through detailed control of adsorbent types, blends, and content levels. It also provides superior protection against fine particles via tailor-made combi grades with laminated efficiency layers, offering excellent adsorption performance alongside low pressure drop.

The versatile platform allows for targeted gas removal and optimized energy efficiency, delivering premium solutions for clean air and clean mobility applications.
