Ahlstrom launches PurXcel™—new molecular filtration media for clean air solutions
PRESS RELEASE, AHLSTROM OYJ, OCTOBER 16, 2025, 12:00 EEST
Ahlstrom, a global leader in sustainable specialty materials, launches Ahlstrom PurXcel™, a new molecular filter media platform designed for clean air applications worldwide. Produced in Turin, Italy, using advanced dry technology, PurXcel™ delivers cleaner, healthier air in cabin and indoor environments.
Indoor air can be 2 to 5 times more polluted than outdoor air, while people spend around 90% of their time indoors*. This highlights the importance of high-performance filtration in enclosed spaces, including vehicles.
Today’s cabin air intake systems must capture a wide range of contaminants while maintaining low pressure drop and silent operation—requirements that are increasingly critical with the rise of electric and premium vehicles. To meet these demands, Ahlstrom developed PurXcel™, a high-performance solution combining optimized carbon loading and low-pressure drop.
PurXcel™ can be configured as a combi-media to remove both gaseous pollutants and particulate matter in a single filter element. Its multiple adsorbent layers can be tailored to target specific contaminants, including volatile organic compounds (VOCs), and inorganic gases such as sulfur dioxide, nitrogen oxides, ammonia, as well as odors. A wide range of particulate efficiency layers is available—extending up to HEPA13—to meet even the most stringent air quality requirements.
Filter media’s excellent pleatability and cohesion enable higher converting efficiency, simplified filter manufacturing and waste reduction. Additionally, its optimized internal structure supports compact designs and whisper-quiet operation - ideal for space- and noise-sensitive environments such as Electric Vehicles and premium cabins.
“PurXcel™ embodies Ahlstrom’s DNA of innovation and our commitment to purify and protect with every fiber,” says Giuseppe Costa, VP Global Filtration. “Beyond cabin air intake, this versatile platform can be adapted to HVAC systems, fuel cell air intakes, and personal protection devices, meeting the evolving needs of multiple industries.”
