acquisition and delivery of mechanically filtered air purifiers to fight Covid and improve indoor air quality (Qai) at Gustave Eiffel University

according to the opinion and recommendations of the INRS and the Hcsp (High Council of Public Health) only a professional range with HEPA filtration certified H13 according to EN 1822 is recommended. It is strongly discouraged to choose devices using physico-chemical air treatment (catalysis, photocatalysis, UV, plasma, ozonation, ...) whose effectiveness in destroying viruses in the air is difficult to verify and which, for some, can negatively impact indoor air quality following incomplete degradation of pollutants leading to the formation of compounds potentially dangerous to health, including CMR (carcinogenic, mutagenic, or toxic for reproduction) Source INRS and Hcsp.The proposed devices will preferably be with an automatic airflow regulation technology depending on the level of presence, or the activity of the room (automatic face-to-face mode)
