Studies have shown that by increasing ventilation rates, you can significantly reduce the risk of indoor COVID–19 contagion. By measuring CO2 Aranet4 infers whether ventilation rates are sufficient thus indicating COVID-19 contagion hazard level. You can use Aranet4 to see if at your home, office, school and any other public indoor spaces are at a heightened risk of COVID-19 contagion, and if extra measures to increase ventilation should be taken. Measure the air quality around you with Aranet4 and stay safe.
