Another reason to monitor CO2 is to make sure the indoor air doesn’t contain high levels of carbon dioxide (CO2) concentration because this can affect a person’s cognitive ability and productivity. Indoor CO2 concentration can make people anxious, sleepy, and unable to concentrate which results in lower performance to complete tasks. Decreasing CO2 levels can increase a person’s productivity. Aranet products monitor indoor air quality, provide real-time data, and receive alerts when CO2 has crossed thresholds and rooms are ventilated in a timely manner, concentration and performance levels increase, improving productivity and overall contentment.
