As technology has advanced, our homes have advanced with it. Those drafty houses of the past have been replaced by new, energy-efficient homes. While this “sealing up” of our homes has saved us money, the downside is that we now seldom breathe "fresh" air like we should. This is complicated by the fact that we now spend 90% of our lives inside.

No matter how good a housekeeper you are, your home is filled with air pollutants. Dust particles, mold spores, animal hair, dander, pollen, dust mites, cleaning chemicals, exhaust fumes, carbon monoxide, virus and bacteria.

Add to these culprits the scores of chemical irritants lurking about...in your carpets, behind the walls, even in the cleanser and waxes you use to keep your house clean.

Air-conditioners, dehumidifiers, even furnaces give these germs, vapors and particles a free ride around your house and into the air you breathe.
