Water treatment for humidification
To ensure the highest quality of water for humidification, UNIFOG Denmark employs several treatment steps:
Consequences of low humidity
When humidity falls below 10% RH, it can lead to several inconveniences:
- Static electricity: Dry air increases static charge, which can be both annoying and potentially damaging to electronics.
- Floating dust: Because the dust becomes more static, it is harder to clean and remains suspended in the air.
The ideal humidity range
The best indoor climate is achieved by maintaining a humidity level between 30% and 50% RH
- Research and practical experience show that the best indoor climate is achieved by maintaining a humidity level between 30% and 50% RH.
- Humidity levels maintained at 30% and 50% RH helps prevent the problems caused by extremely dry air, such as static electricity and dust issues.
Maintaining optimal humidity
UNIFOG Denmark provides equipment that makes it possible to control indoor humidity accurately
- Summer humidity: During summer, when the humidity often exceeds 50% RH naturally, there is typically no need to increase the humidity.
- Dry seasons and climates: In drier seasons or climates, Unifog’s fine atomisation process ensures the water is absorbed by the air immediately, effectively raising and stabilising the indoor humidity.

How the indoor climate affects everyday life
The ability of air to hold water depends on its temperature—cold air holds less water than warm air. As a result, indoor air can become very dry in winter.
For instance, when air at 0°C with 50% RH (relative humidity) is heated to 20°C, it only retains about 13% RH.
In northern Scandinavia, it is not unusual for indoor humidity to drop below 10% RH during the coldest months.
