  Ahlstrom Oyj : Ahlstrom to collaborate with Dow Chemical Company on water
                           filtration applications

Ahlstrom Corporation PRESS RELEASE March 21, 2013 at 14.10

Ahlstrom, a global high performance fiber-based materials company, announces
that it has entered into a collaboration agreement with Dow Water & Process
Solutions (DW&PS), a business unit of The Dow Chemical Company (NYSE:DOW), to
use Ahlstrom's Disruptor® technology in drinking water applications. Ahlstrom
Disruptor® is a unique nanoalumina technology designed for a wide range of
water filtration applications.

Ahlstrom's fiber-based materials match the global megatrends, such as
environmental awareness, resource scarcity and urbanization. As a response to
the need for clean water, Ahlstrom has developed the Disruptor® technology
that can be used in removing a wide range of tiny contaminants from water.
DW&PS will incorporate Ahlstrom's high performance, break-through Disruptor®
filter medium into a new set of drinking water purification products that
provide excellent pathogen rejection while operating at high flow and low

"One of the key goals in our product development is to create products that
purify air and liquids in a sustainable way. We are excited about the
opportunity to work with Dow since we see a wealth of opportunities for
providing pure water solutions through combining our expertise with Dow's
industry-leading product offering," says Fulvio Capussotti, Executive Vice
President, Advanced Filtration, Ahlstrom.

Ahlstrom Disruptor® virtually removes microorganisms that can cause sickness.
Its unique combination of large pore size and very high electrical attraction
potential enable efficient removal of virus-sized particles at a high flow
rate at very low pressure. Ahlstrom Disruptor® can be utilized in a number of
drinking water applications, such as under-the-sink purification, tap water
filters and water pitcher filters. It can be used in areas with no
electricity, it requires no use of chemicals, and does not generate waste

"Global trends such as population growth and urbanization put pressure on
already strained water sources," said Snehal Desai, global business director
for DW&PS. "We see a real need for new innovations to expand access to clean
safe drinking water in an easy, effective and sustainable way. Our
collaboration with Ahlstrom extends our product offering to people who need
effective water treatment but may not have access to pumps or electricity."
