Towards carbon neutrality

Towards carbon neutrality

M-Filter Group has launched a project towards carbon neutrality. The carbon footprint will be calculated in accordance with the greenhouse gas (GHG) protocol, which is a generally accepted and broadly used calculation method.

We will start by identifying the carbon footprint of our operations. To this end, we have selected Green Carbon Finland as our partner. Green Carbon has the first ISO 14064-certified carbon sinks in the Nordic countries. It is important to us that our carbon footprint is calculated by a reliable external expert organisation.

We will first identify where emissions are generated and how they can be controlled and reduced. After this, we can take concrete action for the environment. We will offset part of our emissions by using carbon sinks. Green Carbon’s certified carbon sinks are Finnish forests and partnership projects with Finnish landowners. M-Filter will offset direct emissions from its operations by using certified Finnish carbon offsetting.

Our aim is to make our operations carbon neutral by means of emissions reductions and carbon offsets. We will draw a climate roadmap to lead us towards low carbon business.

Clean Finnish air conquers the world

Clean Finnish air conquers the world – a new group becomes the market leader

Clean air specialists Oy M-Filter Ab and Filterpak Oy have merged in a transaction where Oy M-Filter Ab has acquired all shares in Filterpak Oy, which operates in Hanko, Finland. With the transaction, the owners of Filterpak Oy Peter Nordlund and Thomas Nordlund become co-owners in Oy M-Filter Ab and join the Board of the group, while continuing in their previous positions at Filterpak. Kai Liesmaa will continue as the Managing Director of the group. The transaction will not affect the employees of the companies. 

Oy M-Filter Ab manufactures air and oil filters for various international top brands globally. With the merger, the group strengthens and expands its operations in the clean indoor air solution sector, where Filterpak has been among the top companies in the field. 

We are very happy that two strong domestic operators in this sector are merging. This arrangement will allow us to outpace the market as we grow globally, says Kai Liesmaa, the Managing Director of Oy M-Filter Ab. 

Peter Nordlund, the Managing Director of Filterpak Oy, considers the merger a significant step for both parties and for domestic production. 

With the merger, we join the ranks of major filter manufacturers in Northern Europe. I am delighted that jobs in the newly created growth company remain in Finland, Nordlund says. 

The importance of healthy indoor air is immense: According to Sisäilmayhdistys ry, good indoor air reduces illnesses, increases comfort, and improves working efficiency. The cost of poor indoor air quality is measured in billions of euros in Finland alone. 

The air in Finland is the cleanest in the world (WHO 2017), so it is only natural that the best indoor air filtration solutions also come from Finland. Clean outdoor air is often taken as granted here in Finland, but we have a lot of room for improvement as regards the quality of indoor air. And the situation is even worse in many other countries. We now have a unique opportunity to create a Finnish success story, Liesmaa summarizes. 

After the merger, M-Filter Group comprises three companies: Oy M-Filter Ab, PL-Filter Oy, and Filterpak Oy. The factories of Oy M-Filter Ab are located in Haapavesi, Finland, and Druskininkai, Lithuania, while PL-Filter Oy is located in Vimpeli, Finland, and Filterpak Oy in Hanko, Finland. The group also comprises Oy M-Filter Ab’s sales companies in Germany and Russia. The group’s turnover for this year is expected to reach approximately 23 million euros and it employs around 200 people.
