Up to 72 trillion microscopic irritants or allergens find their way into your home every day.  These include dust, pollen, pet hair and dander, dust mites, mildew, lint, fungus, tobacco smoke, cooking grease and bacteria. These particles may be as small as .3 microns – so small that 2 million of them could fit on the period at the end of this sentence.

The problem for people with allergies or asthma is obvious, but many of these particles are so small that the natural defenses in your nose and throat can’t filter them out, and they can get deep into your lungs, which can cause symptoms like coughing, watery, itchy eyes, or stuffy noses.  Indoor air pollution, which can be from 2-5 times as bad as outdoor air pollution can bring on or complicate such maladies as asthma, stroke, heart attack, respiratory disease and other serious illnesses.
The flu season, which peaks during the winter when homes are closed up tight, complicates the issue of air quality, as influenza can easily transfer from person-to-person simply through sharing the same air. Every year nearly 20,000 Americans are hospitalized due to complications from the flu, often because of issues with respiratory problems, asthma and allergies. While it is impossible to avoid other people who live in your own home when you are sick, having an air purifier in your home can help to minimize the germ interaction in the air and help prevent the flu from spreading.
Air cleaners, such as The AccuClean Whole-Home Air Filtration System from American Standard, can catch up to 99.98 percent of allergens in the filtered air down to .1 microns.  This type of furnace-mounted filtration system is 100 times more effective than standard 1” furnace filters or stand-alone ionic type appliances.
When you consider that the average home accumulates over 40 pounds of dust in a year, having an air cleaner that removes 50% of that dust makes a house cleaner and healthier.  While the obvious benefit is that you will dust less often, even more important is that the inhabitants in your home will breathe  50% less dust, making everyone’s life better.
