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.
While too much humidity can create a breeding ground for mold, a lack of humidity can lead to health issues like dry skin, nose bleeds and allergy attacks. In order to keep your mold risk at a minimum, the Mayo Clinic recommends keeping your indoor relative humidity below 50 percent.Note, however, that humidity below 30 percent can create dangerously dry conditions.f you decide to use a dehumidifier, keep the filters and reservoirs clean, because mold feeds on dirt and a dirty filter can also elevate your mold risk. If you use a humidifier for dry air, keep an eye on your hygrometer and turn the humidifier off if the indoor humidity nears 50 percent.
