Ahlstrom, a global leader in fiber‑based specialty materials, announces the launch of a new generation of glass microfiber media for HVAC filtration, designed to meet the growing demand for responsible, high‑performance air filtration solutions. Produced in Turin (Italy), this new platform is made without any intentionally added PFAS while maintaining the durable water‑repellent properties essential for HVAC systems, enabling manufacturers to rely on safer materials without compromising functionality.

Leveraging advanced fiber engineering, the media delivers measurable performance gains - achieving up to 20% lower initial pressure drop and improved pressure build‑up compared with standard glass media on the market. This contributes to better energy efficiency while maintaining stable filtration performance throughout the filter's lifetime.

Engineered for industrial reliability, the media offers excellent processability and pleat ability, helping reduce waste and limiting the risk of defects during converting. Covering particulate efficiencies from ePM1 65% to ePM1 80% (ISO 16890), the range is suitable for a broad set of HVAC applications, from residential and commercial systems to more demanding industrial environments. By combining reliable moisture management with improved energy performance and robust converting behavior, this new glass microfiber family provides a future‑ready solution aligned with evolving regulatory requirements and increasing sustainability expectations.

"Our new HVAC glass microfiber platform demonstrates how performance and sustainability can be integrated from the earliest stages of development," says Stéphanie Pigeot-Rémy, Head of Global R&D and Product Development. "With this new development, we support our customers in their transition toward responsible filtration solutions, fully aligned with our purpose to Purify and Protect with Every Fiber for a Sustainable World."
