Many of those affected are familiar with the problem in the cold months of the year, when there is strong heating: if the room air is too dry, it irritates the eyes and respiratory tract and can even lead to chronic headaches.

The solution is a humidifier that keeps the relative humidity in the room at a constant optimum . If you are thinking about buying a humidifier, you should consider a few points and be aware of the fact that air humidification does not automatically mean air purification.

If the air humidity is also in an optimal reference range, which counteracts the above-mentioned complaints and symptoms, other dangers come to the fore at the same time , which threaten as potential risks in the event of improper use and insufficiently hygienic cleaning.

Air humidification: yes, but correctly and with a sense of proportion

For people who suffer from irritated mucous membranes or who even complain of headaches due to insufficient humidity, a professional air humidifier is an acquisition that is worthwhile and counteracts the symptoms quickly and effectively .

However, if the humidity is too high, mold growth can result. Therefore, it is important to have the right setting for a comfortable and healthy feel-good climate with optimal humidity. The relative humidity in living spaces should be between 40 and 60 percent , but never below 35 percent and above 65 percent. 

With a hygrometer, the humidity in rooms can be measured reliably with just one movement. A preliminary test helps you decide whether you should consider purchasing a humidification system.

In some rooms, the use of an air humidification system can be particularly recommended: This applies, for example, to rooms in buildings where the fabric of the building consists to a large extent of building materials with high sorption properties . Some building materials such as chipboard, wood or plaster of paris absorb the air humidity to a greater extent than conventional masonry.

What is a humidifier good for?

A humidifier regulates the relative humidity in closed living and working spaces. In this way, an air humidification system can help to alleviate or prevent typical symptoms and complaints that are directly attributable to excessively dry air .

A correct and needs-based setting of the humidifier is important: If the humidity is too high, not only mold has an easy time. The risk of germs, viruses and bacteria being transmitted also increases.

Which humidifiers are the best?

Humidifiers come in all shapes and colors. This is due to the fact that the various humidification processes are based on different technologies . A distinction is made between passive and active air humidification: All processes aim to regulate the air humidity, whereby there is no risk of overhumidification with passive humidification processes.

Before deciding on one of the technologies mentioned above, personal needs and requirements should be weighed and taken into account. The decision can be influenced by the following aspects:

  • Volume of the device
  • Energy costs
  • Hygiene and maintenance needs
  • Water hardness
  • Risk of potential overhumidification of the room air

Where should a humidifier be located?

There are many potential places where a humidifier can be found in everyday life. However, there is one important aspect that you should keep in mind when choosing the right location for an air washer : to avoid mold formation, a distance of at least 10 to 30 centimeters should be maintained (depending on the model) to furniture standing around .

Placing the air washer directly in front of cupboards or walls is also not recommended: the moisture threatens to condense on the directly adjacent surfaces. The risk of mold growth is increased.

A location that is as free as possible in the room not only reduces the risk of mold formation, but also guarantees that the air enriched with moisture is optimally distributed in the room.
