Monitor the humidity in your home.
HealthyHouseTM CleanAir Tip
The humidity in your home should be between 40% and 60% relative humidity. Humidity, the amount of water vapor in the air, is measured with a humidity gauge known as a hygrometer. Above this range, mold can thrive easily. Below this range, bacteria and dust mites will tend to thrive. Basements are an important area to keep the humidity level in check. Basements tend to be damp and typically do not have a lot of air flow. Mold will thrive in humid environment and can grow on almost anything including dust and cardboard. A dehumidifier can be used to remove moisture from the air. It should be set at 40 - 45% relative humidity.
