AIR Control COVID: with Veolia, monitor ventilation and limit the risk of Covid-19 spreading

Although the World Health Organization (WHO) has today confirmed that in addition to barrier gestures it is imperative to ventilate indoor spaces to limit the spread of Covid-19 by aerosols, it is not always clear when and for how long this should be done. The volume of the room, the occupation rate, the level of ventilation, the impossibility of wearing a mask, etc. are some of the factors that have to be taken into consideration. In school catering spaces in particular, the French government has recently recommended monitoring indoor air quality, for example with CO2 sensors. Veolia, an air quality expert, has developed a new comprehensive monitoring and warning system that offers this type of solution: AIR Control COVID.


Carbon dioxide and fine particle levels are good indicators of indoor air quality. The higher they are, the more likely it is the air could be contaminated with viral particles and the greater the need to ventilate. With AIR Control COVID, Veolia is capitalizing on its expertise in indoor air management by deploying sensors equipped with indicator lights that are capable of measuring levels and alerting occupants to the need to ventilate the space1. Personalized support is also available:

  • Identification of high-risk indoor spaces and representative control points along with air quality professionals and COFRAC2 accredited expertise.
  • Parameterization of alert thresholds based on local authority recommendations.
  • Provision of a web interface to monitor CO2 and fine particle levels at all measurement points and a report on the effectiveness of the practices.
  • Possibility of supplementing the use of sensor indicator lights with notifications sent to the building manager to warn that thresholds have been reached.

AIR Control COVID allows you to keep an eye on the air quality and help control the spread of the virus. 


1. Sensors provide indicators and do not measure the viral load in a room. 

2. The OFIS AIR division, belonging to the Veolia Group, is COFRAC accredited No. 1-6188 (scope available on the website of the French Accreditation Committee) for monitoring indoor air quality in establishments open to the public (LAB REF 30), meeting the requirements of standard NF EN ISO/CEI 17025: 2017. The accreditation covers benzene, formaldehyde, carbon dioxide and the sampling strategy
