Extremely accurate and easy to use. After taking readings all through our buildings it now stays plugged in and on in the main office wall where the reading fluctuates between 420 early in the morning before anyone arrives and 853 mid day which is still well below the level I had heard we should keep CO2 to know we had a good air exchange.

Carbon dioxide is not an air pollutant, but it can still harm us when concentrations are too high

In response to the COVID-19 events, there has been a highlighted need for work environments to have appropriate ventilation in order for workers to be able to safely return to the workplace once lockdowns are over.

SARS-CoV-2 spreads through the air. The risk of COVID-19 infection is considerably higher in an indoor environment, and it’s even higher when indoor spaces are not ventilated correctly.

Respiratory air from breathing and speaking accumulate in indoor spaces, much like cigarette smoke but invisible. Spending as little as 10 minutes in a poorly ventilated room is less of a risk than spending hours in there – so homes and workplaces are high risk.

Correct ventilation is the best way to reduce the risk of COVID-19 infection and spread, in conjunction with other saftey measures such as density limits, the use of face masks and the use of air purifying devices.

COVID-19 transmission is at a higher risk when:

  • Venue: Multiple people indoors, where social distancing is often harder.
  • Poor Ventilation: Staying in one place with limited fresh air.
  • Vocalisation: Talking, shouting or singing will increase aerosolisation of the virus.
  • Time: The amount of time spent in the venue in relation to the risk. Less time is better.

In order to mitigate these risks the following solutions are advised:

Use a CO2 metering device to check and to monitor ventilation in the space. This tells you how much of other people’s exhaled breath you are inhaling. If it is a public space, consider making the reading visible to the public. Don’t guess, test. CO2 meters are cheap and easily accessible.

Improve ventilation to the target level of less than 800 ppm.

Improve conditions using air purifying devices. At a minimum, these should have a HEPA filter and the size of the unit should be matched to the space. Alternatively, relocate activities outside or to a better-ventilated venue.

By ensuring we breathe fresh air, we can avoid most COVID transmission. Where we can’t freshen up rooms, we need good masks, filters to clean the air, and less people.
