Humidity levels in your home can lead to mold and mildew
The first sign that you should be watching humidity levels in your home is when there is frequent condensation on windows. Some condensation is normal. If windows are frequently foggy you need to take notice. When moisture levels are high household condensation can be seen on a number of surfaces in your house. Condensation occurs when water vapor adheres to a window or surface with a cooler temperature. The vapor turns into water droplets on the surface. Other surfaces that the vapor can appear as condensation on is countertops, floors and walls. When it affects porous surfaces such as walls there is a chance it can penetrate the surface and deteriorate the wall and cause health-threatening mold or mildew.
Humidity is a byproduct of human life. Washing machines, dryers, boiling water, steamy showers, even our breath are sources of moisture. Keeping your home’s humidity under control maintains healthier indoor air quality. Here are suggestions to control humidity levels in your home before it becomes a mold problem:
- Circulate the air in laundry rooms, bathrooms and kitchens with ventilation fans
- After showering squeegee and dry the shower enclosure and run the ventilation fan for about 30 minutes to eliminate humidity.
- Allow air to flow through your home by leaving interior doors open.
- Make sure your humidifier is set to the right outside temperature settings.
- Allow for appropriate ventilation through scrawl spaces, basements and soffits.
Many modern homes use Heat Recovery Ventilators (HRV). Stale and humid air is extracted through exhaust ventilation. It brings in fresh air and heats or cools it accordingly.
Ideal Relative Humidity Settings
Relative Humidity Settings Moisture levels must be controlled within the home. The following settings are recommended: Relative humidity should be as follows; Summertime is 50 per cent to 60 per cent
Outside Temperature…Living Temperature…Inside Relative Humidity (inside home)
Above 0°C…21°C…40 per cent
-5°C …21°C…35 per cent
-10°C…21°C…30 per cent
-20°C …21°C…25 per cent
-30°C …21°C…20 per cent
