Carbon Dioxide parts per million (CO2 ppm) - what's it mean?

CO2 ppm - What does it mean?

CO2 ppm, (carbon dioxide parts per million) is basically an indicator of how fresh the air is in an environment. Humans and other animals produce carbon dioxide and breath it out.

PPM stands for parts per million - it’s a unit of measurement. So for example if the CO2 ppm was 650 there would be 650 molecules of carbon dioxide for every million molecules of air in that environment.

So what’s all the fuss about?

Breathing in high levels of carbon dioxide can make you feel sluggish and tired.

For example when the CO2 level reaches 1500ppm your ability to concentrate will have reduced by 50%. Also the greater the CO2 level the greater the risk of acquiring an aerosol spread virus like COVID, influenza and monkeypox.

So what’s a normal level?

Outdoor ‘fresh air’ has a CO2 level between 400 to 450ppm

What’s an acceptable level indoors?

Most countries have set a maximum limit for indoor air CO2 levels at 800ppm

However when you start using a carbon dioxide monitor you’ll notice there are many places that well exceed this threshold placing people at unnecessary high risk.

Our mini carbon dioxide have a numerical and colour display and alarm when certain thresholds are reached. Blue - CO2 below 800ppm Yellow - CO2 800 to 1000ppm Orange - CO2 1000 to 1500ppm (a double beep will alarm at 1000 and 1200ppm) Red - CO2 greater than 1500ppm (a continuing beep will alarm).

Alarms on the mini CO2 monitor can be switched off by pressing the button twice.
