What is the recommended relative humidity level to help prevent mold growth?

To effectively prevent mold growth, it is essential to maintain relative humidity levels below 60%. Mold thrives in environments where humidity is high, as moisture is one of the primary conditions necessary for mold spores to germinate and grow.

When relative humidity remains below 60%, it significantly reduces the chances of mold development on surfaces and in the air. This guideline is particularly important in areas susceptible to moisture, such as bathrooms, basements, and kitchens, where humidity levels can naturally be higher due to various activities and conditions.

Other choices indicating higher humidity levels would foster an environment conducive to mold growth, thereby increasing the risk of health issues and property damage associated with mold infestations. Hence, keeping humidity levels consistently below 60% is the proven methodology for mold prevention.
