With a CO2 monitor, you measure the overall air quality in your home. You not only measure the carbon dioxide, but you can also read the humidity and temperature, for example. We also have CO2 monitors that indicate the level of fine dust in the air. Without these monitors, bad air quality goes unnoticed and can cause fatigue, stuffiness, and allergies. To prevent this, the CO2 monitor gives a message when you need to ventilate your house. Do you want to keep track of air quality? Use a CO2 monitor with an app connection.
