The more washable surfaces in your home the better. Choose furniture with smooth wooden surfaces and simple lines, walls that can be washed easily, washable cotton curtains, blinds that wipe clean, and floors of polished hardwood, tile or linoleum. Air purifiers can dramatically improve the quality of air inside your home. The National Bureau of Standards states that air filtered by a HEPA unit is free of 99.97 percent of all contaminating particles. Air conditioners and humidifiers are very beneficial during the appropriate season, but they also collect mold and can cause problems if they are not cleaned regularly.
Mold grows in damp and humid areas such as basements, bathrooms, closets, attics.
Check the house for damp areas that might conceal molds. Throw out all old or unused newspapers, books, magazines, clothing and articles that are sources of mold and mildew. Allergic persons are often supersensitive to odors that can trigger an attack at any time. Scented fabric softeners and laundry detergents are especially irritating. Encase mattresses, box springs and pillows in allergy-proof covers.
