Sometimes, humidity or dampness (water vapor) in the air can supply enough moisture for mold growth. 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.
Since mold growth needs 24-48 hours of high humidity, interrupting the cycle by controlling humidity during unoccupied times is a cost-effective strategy to keep mold dormant. On a warm, rainy day, the ventilated, occupied classroom has a water load of 16-17 lbs. of water per hour.
