Today, most of us spend more than 90% of our time indoors. And since indoor air is often dirtier than outdoor air, it's very important to consider air quality when building an indoor weather system. Dust, dirt, pollen, molds and other contaminates are often recirculated throughout your home. This dirty air can damage your furnishings as well as affect the comfort of your family.
Traditionally, furnace filters were designed to protect the furnace and fans. With increased air quality awareness, filters are now being installed to reduce exposure to particles which can affect your health.
The particles you breathe in your home come from a variety of sources including:
- dust on floors or other surfaces that are disturbed by activity in the house
- pollutants generated by smoking, burning candles, cooking, doing laundry, etc.
- hair and skin flakes from humans or pets
- particles from the outside air which come into your home with infiltrating air
