What Filterpak Oy Ab Ltd does

Filterpak Oy Ab Ltd is a Finnish air filtration manufacturer founded in 1994, producing synthetic air filters and custom air purification solutions for B2B customers across general ventilation, industrial processes, and cleanroom applications. The company operates three production facilities in Hanko (headquarters), Salo, and Vimpeli — the latter two absorbed through the 2023 merger of Filter Partner Oy and PL-Filter Oy into the Filterpak brand. The product portfolio spans commodity ventilation filters (panel, bag, compact/cartridge, small-equipment, large-surface, gas-adsorption), high-efficiency EPA/HEPA/ULPA filters under the Nanoclass line (via MANN+HUMMEL partnership), ATEX-rated explosion-proof filters for hazardous environments, paint-shop filtration materials, and a NeSu sub-brand of Finland-manufactured face masks. The company also offers OEM/private-label contract manufacturing, packaging products under customer brand requirements.

Filterpak runs a hybrid B2B go-to-market: a Finland-wide direct-sales team of eight regional representatives performing site surveys, product demonstrations, and filter-selection consultation; an extensive domestic distributor network; a B2B e-commerce platform (b2b.filterpak.fi); and the MyFilterpak customer portal for repeat ordering. Private customers are redirected to partner Suodatinkeskus Suomi Oy, allowing Filterpak to stay focused on B2B accounts. Pricing is quote-based for custom products and unit-priced for the 2026-launched Varastomallisto stock line, which carries a 5-working-day delivery commitment and a 98.8% on-time reliability rate.

The company holds ISO 9001 and ISO 13485 (medical-device) certifications, the Key Flag (Avainlippu) designation for domestic production, and memberships in the IAQe ecosystem and Finnish Indoor Air Association (Sisäilmayhdistys Ry). In October 2025, Huoltovarmuuskeskus (Finland's National Emergency Supply Agency) selected Filterpak as a trusted domestic filtration supplier, providing a defensible position in public-sector and critical-infrastructure tenders. Revenue is not publicly disclosed; the company operates as an independent private limited company with no external funding events on record.

Direct peers

• Camfil: Headquartered in Stockholm, Sweden, Camfil is one of the world's largest air filter manufacturers with a strong Nordic presence across general ventilation, HEPA/ULPA, and industrial filtration. It is the most directly comparable peer to Filterpak in product range, customer verticals, and Nordic market coverage.
• BWF Group: German family-owned manufacturer of industrial filter media and finished filtration products, with a strong focus on dust collection, gas-phase, and process filtration. It is a direct comparably sized peer to Filterpak in industrial filter manufacturing depth.
• Troy Filters: Specialized manufacturer of industrial and cleanroom air filtration products serving healthcare, pharmaceutical, and process-industry customers. Comparable in niche industrial/cleanroom focus though operating primarily in North America.

Broad incumbents

• AAF Flanders (American Air Filter): Global manufacturer of air filtration solutions for commercial, industrial, healthcare, and cleanroom applications. AAF competes with Filterpak across HEPA, panel, and bag filters but at significantly larger scale and broader geographic reach.
