In the lively business pulse of Paris, one of the largest European trading companies manages to ensure clean, safe and comfortable climate for its thousands of employees and visitors on a daily basis. To keep a constant standard for internal atmosphere for its hundreds of administrative locales, the company has chosen the professional air cleaning systems made by Camfil - City M and City S, equipped with а HEPA H14 filter of premium class. The solution allows for effective cleaning without requiring fixing, complex installations and with proven reliability.

The central and training locale of the company is in the Paris region Île‑de‑France – one of the largest corporate hubs in Europe. This is a grand office complex, with a daily visitor rate between 3 and 4 thousand people. The buildings are used to prepare new employees, hold seminars for franchise partners, internal business meetings and daily administrative work. The rooms are varied, from small individual cabinets and offices for two people, to large lecture halls and open spaces. This dynamic environment requires a solution to maintain stable air quality regardless of the intensity of human presence and the workload, while at the same time ensuring comfort for everyone that works and trains in the building.

Camfil offers the City series—professional mobile air purifiers that combine high-efficiency HEPA H14 filtration with low noise levels and ease of use. Approximately 180 City M and 350 City S units have been installed, covering spaces ranging from 45 to 75 m².

"The HEPA H14 filters are certified according to EN 1822 and individually tested, with each filter featuring a serial number and a test report. This guarantees actual measured efficiency that meets the highest European filtration standards," the company explained.
