How to Reduce the Risk of COVID-19 Infection with Aranet4 Air Quality Sensor?
Many studies demonstrate that COVID-19 can be spread by aerosols, therefore proper ventilation is more important than ever. How to make sure we protect ourselves and avoid getting infected by the small droplets in the air?
- Proper ventilation can reduce the risk of COVID-19 infection
- CO2 concentration can be used as an air quality indicator and can be monitored with sensors such as Aranet4
- Aranet4 warns when the air quality has become unhealthy and you should take care of the airflow in the room
A mounting body of evidence ¹ ⁴ reveals that aerosols are a possible transmission route for the SARS-CoV-2 virus. Aerosols are small droplets averaging around 5 μm in size and they are released during talking, singing, coughing and sneezing. These particles have been shown to contain the SARS-CoV-2 virus ² which may remain infectious for up to 3 h. ³
The danger lies in the fact that due to their small size these aerosols can remain in the air for up to 9 minutes. ⁴ It has been shown that proper ventilation can shorten the time it takes to remove most of the small droplets down to 30 seconds ⁴ making indoor spaces safer.
The Federation of European Heating, Ventilation and Air Conditioning Associations (REHVA) recommends using CO2 measuring devices indoors to assess risks of SARS-CoV-2 transmission via aerosols ⁵ ⁶. CO2 is a gas produced when we breathe and its concentration can be a good indicator of insufficient ventilation.
Aranet4 is an easy to use CO2 monitoring device that lets you know right away if the ventilation is sufficient and whether you are at an elevated risk of SARS-CoV-2 infection via aerosols. Visual color indicators as well as a sound alarm will notify you when action (opening windows, turning up the ventilation or leaving the room all together) must be taken.
You can only improve what you can measure. Let Aranet4 make your facilities safer!
