It is now widely accepted that poor air qaulity and inadequate levels of ventilation can be a contributing factor to the airborne spread of the SARs-Cov2 virus.

It remains unclear exactly how long the COVID-19 virus can survive in the air, it has been suggested that it may be possible for the virus to survive in small droplets exhaled by an infected person for up to 3 hours.

These droplets can travel distances of meters or tens of meters in the air and carry their viral content. Science explains the mechanisms of such transport and there is evidence that this is a significant route of infection in indoor environments.

The World Health Organisation (WHO) has urged hospitals to better manage their air quality and therefore believe that this is a contributing factor to the spread of the virus. 


Research on the transmission modes of COVID-19 is ongoing, the current understanding is that humidity, particulate and carbon dioxide levels all play an important role in reducing the likelihood of airborne transmission. 

Maintaining good ventilation and air qaulity within indoor environments is key against combating the spread of the virus in the workplace. The most up to date scientific knowledge states that the following environmental conditions have the biggest impact at reducing the spread of the virus:


Relative Humidity 40-60%

Particulate (PM2.5) levels <10 micrograms

Carbon Dioxide 500-600ppm


Our expert technicians will initially discuss your concerns in relation to air quality and agree a testing strategy using wireless sensors targeted at monitoring air quality in relation to good ventilation levels.
