How is mold growth prevented?
Hide Controlling moisture is the most important factor. Mold will not grow if moisture is not present. A properly constructed building is designed to keep the inside of a home dry, which will not allow mold growth (1, 2, 3). As part of routine building maintenance, buildings should be inspected for evidence of water damage and visible mold. The conditions causing mold (such as water leaks, condensation, air infiltration or flooding) should be corrected to prevent mold from growing (13). Specific Recommendations adapted from CDC recommendations (13) • Keep the overall humidity level in house low enough to minimize the occurrence of localized relative humidity greater than the 80% threshold that will support active mold growth. The appropriate indoor humidity will depend on the climate and, to some extent, on the level of insulation in the building. • Use an air conditioner or a dehumidifier during humid months. Some air conditioners may not remove sufficient moisture from the air and an
