In fact, indoor air can be two to five times – and sometimes up to 100 times – more polluted than outdoor air.
According to the United States Environmental Protection Agency (EPA), indoor air pollution ranks among the top five environmental dangers to the public. This is bad news since most Americans spend 90% of their time indoors.
And the problem with these inside pollutants is magnified if your home is sealed up tight for energy efficiency. Then the pollutants will accumulate to levels that can pose health and comfort problems
So what are the sources of these airborne contaminants? There are several, but here’s a few of the most dangerous.
A plethora of household products contain contain organic solvents. These products include:
The dangers of these products depends on a few factors, including the amount you’ve been exposed to and the exposure time.
To avoid the adverse effects of these products, make sure to read the warning labels.
For example, certain hazardous products will tell you to use them in a well-ventilated area. In that case, go outside or open up windows and use exhaust fans.
You’re probably not surprised to hear that tobacco smoke is a major pollutant that’s bad for your lungs. Tobacco smoke is the leading cause of lung cancer and increases the risk of heart disease.
According to cancer.org, “Tobacco smoke contains more than 7,000 chemical compounds. More than 250 of these chemicals are known to be harmful, and at least 69 are known to cause cancer.”
So smoking not only hurts the one smoking, but those around the smoker as well.
Your furnace, gas stoves and ovens and fuel space heaters produce carbon monoxide (CO), a deadly, poisonous gas that’s indiscernible to your senses. The only way to detect it is with a carbon monoxide detector.
When operating correctly, your furnace and gas appliances vent this deadly gas to the outside of your home. However, if equipment is not properly installed or maintained, carbon monoxide can leak into your home and cause CO poisoning.
Hardwood plywood, wall paneling, particleboard, fiberboard are all made with adhesives that contain urea-formaldehyde (UF) resins. The formaldehyde in these resins is a colorless, pungent-smelling gas. It can cause:
According to the EPA you should always “ask about formaldehyde content of pressed wood products, including building materials, cabinetry, and furniture before you purchase them.”
Your air ducts carry the air from your heating and cooling system around your home. But a leak or hole in the ducts can suck up dust and other contaminants in your attic and blow them out your supply vents located throughout your home.
Signs of leaky air ducts include:
While you can seal duct leaks on your own, it’s best to get a professional to do it, especially if the leaks are in a part of your ducts that you can’t easily reach.
While this isn’t a comprehensive list of pollutant sources, this is a good start of the most dangerous ones.
