There are visual signs to look for when determining if excessive moisture/ high humidity is present in your home or property, ranging from damp drywall, condensation on windows, or mold growth.
There is a common test you can try to determine the relative humidity inside your home, apartment, or property.
The Ice Cube Test*:
- Place two or three ice cubes into a glass, add water and stir.
- Wait three to four minutes.
- If moisture does not form on the outside of the glass, the air is too dry; you may need a humidifier. If water has condensed on the outside of glass, the level of relative humidity is high.
*Note: Do not perform this test in the kitchen. Cooking vapors may produce inaccurate results. You can place the glass in any other room where humidity is a concern.
High indoor relative humidity includes some general telltale signs. You should also watch for signs of frequent fogging of windows, which may indicate too much humidity. The appropriate relative humidity will allow only slight condensation along the edges or corners of windows. More condensation could be damaging. Moisture buildup or mold on closet walls or room ceilings and walls also indicates high humidity.
Humidity should be monitored daily since outside temperatures will change. Consider purchasing a digital hygrometer (widely available) and check it regularly. By monitoring our indoor air quality, we can avoid the negative effects associated with excess moisture. Indoor humidity levels will range, depending on the season. As recommended by the Environmental Protection Agency, indoor humidity should be kept below 60%. This range will not only provide the best comfort for residents, but also helps to protect drywall, furniture, building materials and more.
Innovative Dehumidifier Systems was developed to provide a supplemental dehumidification system that efficiently and consistently controls moisture. Designed for everyday use, the ENERGY STAR® Certified IW25-4 In Wall and On Wall dehumidifier helps resolve the problems associated with high indoor humidity.
