What is an effective way to reduce mold growth indoors?

An effective way to reduce mold growth indoors is to both increase ventilation and decrease humidity.

Increasing ventilation helps to improve air circulation within a space, allowing for fresh air to replace stale air. This reduction in stagnant air minimizes the likelihood of moisture accumulation, which is essential for mold spores to thrive. Improved airflow through proper ventilation can help dry out areas that may become damp, particularly in places like bathrooms or kitchens where moisture levels tend to be higher.

Decreasing humidity is also crucial because mold generally requires a relative humidity level above 60% to grow. By using dehumidifiers, air conditioning, or other methods to lower humidity levels, it creates an environment that is less conducive to mold growth. Keeping humidity levels between 30% and 50% is ideal for preventing mold development.

When both increasing ventilation and decreasing humidity are applied in tandem, the effectiveness in reducing mold growth is considerably enhanced, making this combination the best approach for creating a healthier indoor environment.
