An estimated 1,500 hazardous substances can be found in the typical home. According to the Environmental Protection Agency (EPA), indoor air is 2 to 5 times, and sometimes more than 100 times, more polluted than outdoor air.
And an indoor air pollutant is 1,000 times more likely to reach your lungs than an outdoor pollutant. Sniffles, a scratchy throat or watery eyes don't necessarily mean you're sick with a cold or the flu; the air in your home could be making you sick. In reality, about 50% of all illnesses are caused by, or aggravated by, indoor air pollution.
