Derfor bør du have en CO2-indikator - Åbn

That is why you should have a CO2 indicator

The climate was the most debated topic in 2019 – and when you say climate you cannot avoid saying CO2. CO2 is a type of air that occurs naturally in our atmosphere and is produced by burning wood, coal and oil. In our atmosphere, the concentration is approx. 400 ppm (parts per million). But…

The human body is not designed to sense CO2

It is not only burning that emits CO2. When humans and animals inhale oxygen, CO2 is released in the exhaled air.

The CO2 in the exhaled air is not a problem in the open when it is mixed with the fresh outdoor air. Therefore, it was not a problem for our ancestors. When we lived in caves, the body could react to temperature and humidity, because these were threatening elements in the open and the CO2 level was stable.

But today we have enclosed ourselves in buildings, and when many people stay inside a room with insufficient ventilation, the CO2 level will rise as we release CO2 into the exhaled air. It can thus affect our health and performance.

So we have built the world long after the human body was designed, and therefore we are not designed to be able to feel the CO2 level until we are hit by headaches and tired heads in the office.

Visualizing your indoor climate is more important than ever before

Since we spend more than 90% of our time indoors, it is important to keep track of our CO2 level. It is important for us to be able to react to the CO2 level in the bud, and especially in the office or at school, where there is a high risk of an elevated CO2 level.

The Norwegian Working Environment Authority recommends that the CO2 level indoors does not exceed 1,000 ppm for longer periods of time. One way to reduce the CO2 level is by simple ventilation with drafts, so that the indoor air is replaced with the outdoor air.

Therefore, it may be a good idea to acquire a CO2 indicator, indoor climate alarm, CO2 alarm or indoor climate meter, to keep an eye on your CO2 level and indoor climate. The CO2 level is the absolute best parameter that represents your indoor climate, as parameters such as temperature and humidity increase as the CO2 level rises. However, the only parameter we can be sure of effectively venting is – the CO2 level.
