Fortunately, there are many simple tips that can help reduce exposure to harmful air pollutants at home. Prohibit smoking in the 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. 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. If mold growth is evident, the plants may need to be re-potted or kept outdoors.
