There is more to keeping your home clean than just cleaning surfaces like counters and carpeting. A really clean home starts by cleaning the air your family breathes. Did you ever notice dust particles floating in a stream of sunlight? These are only a small fraction of the particles that can be found in the air in your home. Many particles are invisible to the naked eye and can lurk in the air for a long time. These microscopic particles can be a small as .3 microns. For comparison, a human hair is about 50 microns.
And particles in the air aren't just dust. They can include pollen, plant and mold spores, pet dander, lint and dust mite debris. Some particles can carry bacteria and viruses, and many everyday activities in the home such as dusting, vacuuming, cooking and smoking can increase concentrations of these particles.
The U.S. Environmental Protection Agency says the air inside your home can be two to five times worse than the air outside. In fact the EPA identifies indoor air pollution as one of the top five environmental risks to public health. And if you're like many people, you probably spend about 90% of your time indoors.
