Mold

Mold can be found almost anywhere; it can grow on virtually any substance when moisture is present. Outdoors, many types of mold live in the soil and play a key role in the breakdown of leaves, wood, and other plant debris. Without mold we would all be struggling with large amounts of dead plant matter.

Mold produces tiny spores to reproduce. These spores waft through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. There are types of mold that can grow on wood, paper, carpet, foods, even dynamite!

When excessive moisture or water accumulates indoors, mold growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed. There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.

Mold can trigger asthma episodes in individuals with an allergic reaction to it. If mold is a problem in your home, you must clean up the mold and also eliminate sources of moisture:

• Wash mold off hard surfaces and dry them completely.
• Absorbent materials, such as ceiling tiles and carpet, may have to be replaced if they are contaminated with mold.
• Fix leaky plumbing or other sources of water.
• Keep drip pans in your air conditioner, refrigerator, and dehumidifier clean and dry.
• Use exhaust fans or open windows in kitchens and bathrooms when showering, cooking, or using the dishwasher.
• Vent clothes dryers to the outside.
• Maintain low indoor humidity, ideally between 30-50% relative humidity. Humidity levels can be measured by hygrometers which are available at local hardware stores.
• In certain cases, professional duct cleaning may be advisable.

Pollen

Many people are allergic to pollen, and pollen can be an asthma trigger. On high pollen days, stay indoors with the windows closed. Using your air conditioner may help to filter outside air coming into the home.
