What Filtrox does

Filtrox AG is a Swiss depth filtration solutions provider founded in 1938 and headquartered in St. Gallen, Switzerland. The company designs and manufactures filtration products for clarifying and purifying high-value liquids across three primary verticals: Life Sciences and Pharmaceuticals (cell and gene therapy, biologics, plasmid DNA purification, blood plasma fractionation), Food and Beverage (beer, wine, distilled spirits, sugar, olive oil, CBD oils), and Frying Oil (commercial oil filtration and reuse). Its core technology spans alluvial (precoat and body feed) filtration, sheet filtration, and lenticular module systems, with a product portfolio that includes PURAFIX cellulose-based filter sheets, ACTIVASORB activated carbon filter media, DUROFIL support sheets, PURADISC lenticular modules (including single-use PURADISC SU), NOVOX stainless steel plate-and-frame filter presses, DISCSTAR module housings, CLAROX and FILTRAP filter cartridges, CELPURE and PurifiDE filter aids, and laboratory filtration equipment such as PURASPIN, PURACAP, and LABTROX units.

The company generates revenue through direct B2B sales across four streams: capital equipment (filter presses and housings, one-time purchases), consumable filter media and modules (recurring per-batch purchases), laboratory filtration products, and technical services including application support and validation assistance. Pricing is quote-based and not publicly disclosed, with sales conducted through multi-language websites (English, German, Spanish, Italian) and industry events. Filtrox operates from its Swiss headquarters and branches in France, Spain, and the United Kingdom, where a new manufacturing facility opened in Barnoldswick in September 2025. The company is privately held with no institutional investors, funding rounds, or M&A activity disclosed in the available data, and it maintains separate commercial and marketing channels for each of its three verticals, including dedicated LinkedIn presences and active participation in industry events in Europe, Mexico, and Australia.

FILTROX AG is a privately held Swiss Aktiengesellschaft (corporation) with no parent company or public listing. The company emphasizes regulatory compliance in pharmaceutical applications (FDA and GMP standards) and positions its 85-year Swiss quality heritage as a core differentiator. Recent strategic activity has focused on expanding its single-use bioprocessing franchise (PURADISC SU for cell/gene therapy and AAV applications), launching new food and beverage applications (extra virgin olive oil), and establishing a UK manufacturing base to serve European biopharma customers.
