Indoor Air Quality in Classrooms and COVID19 CO2 Meter

According to ASHRAE, the recommended CO2 level in buildings should be no more than 700 parts per million (ppm) above outdoor air. Since outdoor air is approximately 400ppm, indoor CO2 levels should be no more than 1,100 ppm. Note that this guideline is not designed to limit the amount of CO2, but rather to indicate that a proper level of clean air (1520 CFM/person) is being distributed in indoor spaces like …

Why Monitor CO2 in Classrooms?

But how do you know if the air quality is good? The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a highlevel of indoor air quality, is to monitor Carbon Dioxide (CO2) levels within the classroom. Every time you exhale, you release CO2 into the air. Therefore, the CO2 level lets you determine if the room is being properly ventilated with fresh outside air; thereby, helping you gauge the quality …
