Mold - When humidity is high, molds can be a problem in bathrooms,
kitchens, and basements. Make sure these areas have good air circulation
and are cleaned often. The basement in particular may need a dehumidifier.
And remember - the water in the dehumidifier must be emptied and the
container cleaned often to prevent forming mildew.
Molds may form on foam pillows when you perspire. To prevent mold, put the pillow in an airtight cover and tape the cover shut. Wash the pillow every week, and make sure to change it every year.
Molds also form in houseplants, so check them often. You may have to keep all plants outdoors.
Strong Odors or Fumes - Perfume, room deodorizers, cleaning chemicals, paint, and talcum powder are examples of triggers that must be avoided or kept to very low levels.
