The right level of humidity in the home is important for the indoor climate and therefore also important for both health and the structure of the building. Therefore, it is not enough to have either low or high humidity levels, as there are complications associated with both.
Humidity levels should preferably be below 60% to 65% in summer, and below 40% to 45% in winter, but not below 25%.
There are some clear signs of when your home’s moisture level is too high.
This may include, but is not limited to:
- The presence of bad odors – like a wet basement.
- Black spots on walls and windowsills.
- Condensation on inside-facing window panes.
- Bulging wallpaper.
Condensation on inside-facing windows panes in the morning is not unusual when it’s cold outside – especially in the bedroom. However, it is a bad sign if larger patches of water form at the edge of the window or if there is moisture on the windows all year round.
