And with windows and doors shut to keep out the sweltering heat or chilly air, potentially harmful particles such as smoke, pet dander, dust and other allergens often become trapped in the home with no means of escape. In fact, the EPA reports that the air we breathe at home may be two to five times more polluted, and occasionally more than 100 times more polluted, than the air we breathe outdoors. 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.
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. Run the furnace fan continuously, regardless of the outdoor temperature.
