Some companies begin in boardrooms. Ours began beside a river.
In the small Finnish village of Noormarkku, Ahlstrom’s story took root - shaped by timber, craftsmanship, community, and a belief in building for the future.
As we mark 175 years, Noormarkku remains more than our birthplace. It is a reflection of who we are: a company grounded in heritage and guided by a growth mindset that continues to move us forward.
From local roots to global impact, Ahlstrom has grown into a leader in sustainable specialty materials — helping purify water, filter air, enable diagnostics, protect people, and create solutions for a more sustainable world.
Our story is still being written. In the moment, for the future.
