Indoor relative humidity (RH) should be kept below 60 percent — ideally between 30 percent and 50 percent, if possible.
Low humidity may also discourage pests (such as cockroaches) and dust mites..
What temperature should you keep your house to prevent mold?

What is the best humidity for a bedroom?
Between 30 and 50 percentBetween 30 and 50 percent is the ideal range in which the air is moist enough for easy breathing, but dry enough to not feel oppressive.

Will mold die if it dries out?
Mold does not dry out and die but remains inactive for a while if moisture is not available. This means that it can still grow back and multiply when it is exposed to any sources of moisture. Professional mold remediation and moisture control help to keep mold at bay.
Can too much humidity cause mold?
Water is a vital ingredient for mold or mildew to grow. A high relative humidity indicates a high level of moisture in the air. … When warm, humid air comes in contact with a surface that’s cooler than the surrounding air, condensation can occur. When moisture accumulates on porous surfaces, it can cause mold to form.
How high is too high house humidity?
50%An indoor humidity level is too high when it’s above 50%. At this level, your home is susceptible to increased dust mite infestations, as well as mildew, mold growth and other bacteria.
