Impacts of Mold


Mold can cause or worsen asthma, as well as hay fever and other allergies. For children, mold is thought to double the risk of asthma.

Humidity Control

Humidity levels affect your comfort and health inside your home just as much as they do outside. Too much humidity can promote mold and mildew growth. Too little humidity can irritate skin and respiratory passages*. And an imbalance on either side can keep you from feeling comfortable at the normal temperature setting.

Monitoring the Problem

For optimal comfort and health, national studies indicate your home’s relative humidity levels should range between 35 and 50 percent. A humidity gauge or hygrometer from your local hardware store can help you monitor moisture levels.

Managing a Solution

You can manage moisture by repairing any leaks and sealing cracks. Also, be sure to use exhaust fans whenever you take a warm shower or bath. If these steps aren’t enough, you many want to consider products like dehumidifiers and thermostats, which work with your heating and cooling system to help keep humidity under control.

*Exposure to excessively dry air (relative humidity of less than 20%) can cause respiratory irritation.
