How can mold in the household be prevented?

The best way to prevent mold in the home is the control of moisture. Although it is impossible to eliminate all mold spores in an indoor environment, the mold spores will not grow in the absence of moisture, so controlling moisture is the key to preventing mold growth.

  • Leaks in plumbing or other structures that lead to moisture buildup should be identified and repaired.
  • Areas of leakage and water damage in the home should be cleaned and dried within 24-48 hours.
  • Use of an air conditioner or air dehumidifier during humid seasons can help reduce the potential for moisture buildup.
  • Avoid the use of carpets in humid basements and bathrooms.
  • Using fans and maintaining good ventilation in the home can also help prevent or control dampness.
  • Mold inhibitors can be added to household paints.
  • Keep indoor humidity low (ideally between 30%-50%).
  • Use bathroom fans or open bathroom windows when showering.
  • Appliances that produce moisture, such as clothes dryers and stoves, should be vented to the outdoors when possible.
  • Adding insulation can reduce the potential for condensation on cold surfaces (such as windows, piping, roof, or floors).
