Roll goods producer Ahlstrom has increased its price for all filter media products. The move is a consequence of the continuous rise of raw materials and energy costs, most of which are at all-time record levels.

The price increase will affect all filtration grades produced by Ahlstrom globally and will be effective November 1, 2007. The level of increase will depend on the markets and the constituents of the products. Specific details will be discussed with each customer individually by the appropriate business teams in the coming days.
