Poor indoor air quality is an even greater concern for some of the estimated 40 million Americans who live with some form of allergies and the estimated 17 million with asthma. Fortunately, there are many simple tips that can help reduce exposure to harmful air pollutants at home. Never store more than a few pieces of firewood indoors. Drying firewood can generate mold spores, which can easily contaminate an entire house. If you have pets, bathe and groom them often and minimize their access to carpeted areas and bedrooms of anyone in the house with allergies and asthma.
Window coverings are magnets for dust.
Use window shades made of plastic, wood or other washable materials for easy cleaning. Consider using a high efficiency air filter, such as a Filtrete filter from 3M, in the home's central heating and air conditioning system. High efficiency filters not only protect the furnace, but can be up to 30 times more effective than standard fiberglass filters in capturing pet dander and other allergens. Regularly change furnace and air conditioning filters every two or three months, or as required by the manufacturer. Mold can be found in the soil of houseplants-so check them often.
