Volatile Organic Compounds, or VOCs, are gases given off by a variety of things both inside and outdoors. Not all VOCs are produced by man made means; trees, cows, and wetlands all produce VOCs. Most VOCs encountered outdoors are less of a health hazard than those that collect inside your house however because of the reduced concentrations.
Many types of cleaners also give off VOCs, so take time to check them out before you spray them around your home. The old standbys—vinegar and baking soda—work best in most situations and won’t make you sick. Also, stay away from indoor air fresheners as they can also be a source of VOCs in your indoor environment.
