Testing for Humidity
Simple tests and observations can be made to determine the indoor humidity level.
- Mold and moisture buildup is a definite indication of excessive condensation.
- To determine if the relative humidity level is too low, drop ice cubes into a glass with water. If moisture doesn’t appear on the outside of the glass within a few minutes then air may be too dry (low).
