Founded by Werner Frei, the company is now successfully managed by his son Matthias in the second generation. Unifil is committed to Switzerland as a location and produces exclusively in its own factories in Niederlenz, Aargau. Around 140 employees manufacture and distribute a full range of air filters for a very broad spectrum of applications on an area of around 20,000 m2 - from conventional building ventilation to complex industrial applications and pre-filter stages for highly sensitive cleanroom applications.
