Indoor air quality (IAQ) is an important part of any enclosed environment, in particular work/study. Regarding Covid-19, ventilation also plays an important part in reducing virus transmission by dilution and removal of infected particles and droplets.

The established benchmark test for IAQ is to assess CO2 levels. It is generally understood that indoor CO2 levels are a good proxy for the amount of pollutant dilution in occupied spaces and can therefore be used as an indicator for fresh air. We have heavily invested in developing and manufacturing a refreshed CO2 device, one that is able to present live-readings through an e-ink display on the device.

A CO2 molecule is 0.33nm in diameter, but the entire molecule (from centre of O to the other is 232pm). Outdoor air often contains approximately 400ppm (Particles per million). Considering CO2 comes from human breathing and not many other sources, it is important to frequently monitor indoor air quality. An indoor CO2 level of around 1000ppm often indicates poor indoor air quality, and usually many of us should start feeling the effects of thick, poor, air. Should the levels exceed 1000ppm, consider it increasingly worrisome, immediate action should be taken. We can confirm these thresholds have been thoroughly researched, and are to be followed.
