The filtration efficiency of a mechanical filter media remains intact over time compared to electrostatically charged materials the efficiency of which may decrease in humid conditions.

“We work with determination in order to enhance the supply of face masks for consumers in Finland. At the same time, we are further supporting the reopening in Finland once the corona pandemic restrictions loosen,” states Otto Kivi, Sales Manager at Ahlstrom-Munksjö’s Filtration business.

The company announced in April that it will start the production of face mask materials in Tampere. The plant is capable of producing material for more than 10 million masks in the short-term and has the ability to increase capacity to about 30 million masks per month. Earlier in May, the company announced a similar co-operation on face mask supply with other Finnish players.
