To reduce your exposure to mold:

  • Use central air conditioning (not a swamp cooler!) during the summer months. Don’t use a humidifier.
  • Increase ventilation in damp areas (kitchen, bathrooms, etc.) by installing exhaust fans.
  • Regularly clean mold-prone areas with a cleaner that has bleach in it.
  • Limit the number of house plants you keep in your home.
  • Shake excess water off of shower curtains. Don’t let water collect in dish drainers, plant trays, or refrigerator drip pans.
  •  If your home has persistent mold growth from water damage, you’ll need to replace the damaged area. For example, you may need to replace damaged wallboard inside a wall.

You can't prevent a mold allergy from developing, but you can prevent symptoms of an allergic reaction. The best way to prevent mold allergy symptoms is by avoiding mold spores. Although it's almost impossible to avoid mold spores altogether, there are steps you can take to reduce your exposure to mold. To help prevent mold growth in your home, use special air filters in your air conditioner and furnace, and use a dehumidifier in areas of your home that may be especially damp. Since bathrooms can be areas of high mold growth, make sure you clean bathrooms regularly and keep them well-ventilated. If you go outside, consider wearing a face mask to limit the amount of mold you breathe in.

The following tips may help limit your exposure to mold spores, according to the Asthma and Allergy Foundation of America:

  • Wear a face mask when cutting grass and doing yard work.
  • Stay indoors with the windows closed when mold counts are high.
  • Add an air cleaner with a high-efficiency particulate accumulator (HEPA) filter to central heating and air conditioning.
  • Install an exhaust fan in the bathroom if there is no window to open for ventilation.
  • Repair plumbing and basement leaks.
  • Remove bathroom carpeting.
  • Use diluted bleach to clean bathroom tiles and grout.
  • Clean garbage pails and refrigerator door gaskets and drip pains frequently.
