Ahlstrom launches Flow2Save™ filtration media: improved air quality and energy savings for HVAC applications

PRESS RELEASE, AHLSTROM OYJ, DECEMBER 12, 2025 10:00 EET 

Ahlstrom, a global leader in sustainable fiber-based materials, introduces an enhanced version of Flow2Save™ filtration media. The advanced solution is specifically designed to improve indoor air quality while significantly reducing energy consumption. 

Flow2Save™ offers a compelling value proposition built on Ahlstrom’s deep expertise and commitment to sustainable innovation. The nanofiber-enhanced gradient structure extends filter life and reaches the highest energy efficiency while meeting ISO 16890 standards from ePM1 60% to ePM1 80%. 

With advanced media engineering, Flow2Save™ delivers up to 50% higher dust-holding capacity and reduces initial pressure drop by an average of 30% compared to conventional filter media. In filter element evaluations, Flow2Save™ has demonstrated the potential to achieve up to 50% energy savings, supporting more sustainable building operations. 

Efficient filtration is essential for protecting both human health and industrial processes. Flow2Save™, produced in Tampere, Finland, lowers energy use and operational costs while setting a new benchmark in HVAC and Air Intake performance. 

“Made from 100% synthetic fibers and without the use of PFAS, Flow2Save™ is very easy to handle. It is ideal for compact and panel HVAC filter designs as well as for gas turbine and cabin air applications”, says Stephanie Pigeot-Rémy, Head of Global R&D and Product Development, Filtration. “With Flow2Save™, we are redefining air intake filtration standards by combining high efficiency, extended lifetime, and energy savings in one solution”.
