The importance of good air quality

Better air quality starts with a decent air quality meter. A small device that monitors your air quality and indicates when you need to air. So you can be sure of a good indoor climate.

CO2 meter

In various sectors (catering, health care, etc.), a CO2 meter is already mandatory.
It is a crucial item in the fight against spreading viruses.
It is also strongly recommended that a CO2 meter is also installed in other sectors and places.

An excessively high concentration of carbon dioxide has various effects such as:

  • Headaches
  • Concentration problems
  • Trouble with the airways
  • Eye problems
  • Dazed feeling

To avoid these complaints, ventilation is crucial. The air quality meter closely monitors the amount of CO2 and gives a signal when it is too high. Open doors and windows for fresh air or install an air cleaner.  

Belgian legislation states that the concentration of carbon dioxide must be less than 900 ppm at all times and preferably less than 800ppm.

Fine dust

Healthy air goes beyond monitoring CO2. Measuring fine dust is also indispensable when investigating air quality.

Especially buildings that are located near a busy road or near/industrial areas have to contend with an excessive concentration of fine dust.


The effects of increased levels of particulate matter are

  • Shortness of breath
  • Tickly cough
  • Stuffy nose
  • Irritation of the airways

According to the WHO, the number of particles of particulate matter should be less than 10 micrograms/m³ (= <2.5 micrometers).

Air humidity

In addition to measuring the amount of CO2 and particulate matter, it is important to monitor the air humidity.

If the air humidity is too low, viruses will spread more quickly and can lead to respiratory diseases.
Too high a humidity level can cause mould growth and increase dust mite infestation.

It is therefore important to keep the percentage of humidity stable to prevent these effects.

A good humidity level is between 40% and 60%.
