It's the time of year when we nest indoors, visit with friends and family, and, according to the U.S. Environmental Protection Agency, likely breathe some very polluted air -- two to five times more polluted than outdoor air. It's enough to get you all choked up.
Exposure to indoor pollutants such as smoke, dust, dust mites, pollen, pets, radon, mold and others can contribute to respiratory disease, asthma and worse. But indoor air quality can be improved.
* If you have pets, groom them often.
* Window coverings are dust magnets. Use shades made of washable materials for easy cleaning.
* Mold can be found in the soil of houseplants, so check them often. If mold is evident, the plants need to be repotted or kept outdoors.
* Prohibit smoking indoors.
* Place allergen-impermeable covers over mattresses and pillows. Wash bedding weekly.
* Consider a higher-efficiency vacuum filter bag.
* Never store more than a few pieces of firewood indoors. Drying green firewood inside can generate mold spores that can contaminate your house.
* Keep trees and shrubs at least three feet from the perimeter of a home. Tree and shrub roots can give surface water an easy route into a basement, which can lead to mold growth.
* Consider a high-efficiency filter in your central heating or air-conditioning systems. It can reduce airborne particles.
