Indoor Air Quality
Why Clean Air is More Comfortable...
There's a lot about indoor air quality that you might not know and certainly can't see. Up to 72 trillion microscopic irritants, or allergens, find their way into your home every day. They include dust, pollen, pet hair and dander, dust mites, mildew, lint, fungus, most tobacco smoke, cooking grease and bacteria. Many of these particles are so small that your nose and throat can't filter them out, and they can get deep into your lungs.
Studies show that indoor air can be five times more polluted than outdoor air. Exposure to indoor air pollutants has increased in recent years, due to factors like these:
Today's homes are better insulated and more tightly sealed than ever before, sealing in humidity, smoke, dust and other pollutants.
Use of synthetic building materials and furnishings and household cleaners has increased.
The Environmental Protection Agency ranks indoor air pollution among the top five environmental risks to public health.
