They say insanity is the act of doing the same thing over and over again with the expectation of different results, and if that doesn’t define dusting then nothing else does.</br></br>We dust, it gets dusty and so we dust again. It’s a depressing metaphor for life itself, and that’s only half the problem. It’s also boring, time-consuming and, as noted, an ultimately fruitless endeavor that brings only fleeting satisfaction.</br></br>So why do we do it? Well, for <a title="Air Purity" href="http://www.atgstores.com/appliances/home-comfort-appliances/air-purity/" target="_blank">air purity</a>, of course.</br></br><strong>Dust Defined </strong></br></br>Contrary to popular rumor, <a title="Live Science" href="http://www.livescience.com/32337-is-house-dust-mostly-dead-skin.html" target="_blank">dust isn’t composed of human skin</a>; at least, not the majority of it. That stuff usually comes off in the shower. Dust is made up of all kinds of things, but it's mostly just dirt and particles of things in general decay: clothing, carpeting, foodstuffs, dead insects and other random junk.</br></br>So, that’s the good news. What follows is the bad news ...</br></br><strong>Dust Mites</strong></br></br>Unfortunately, what little dead skin there may be in dust is often enough to attract dust mites that feed on it. The American Lung Association <a title="American Lung Association" href="http://www.lung.org/healthy-air/home/resources/dust-mites-and-dust.html" target="_blank">estimates that four out of five American homes</a> have detectable dust mite allergens (fecal matter and body fragments) in at least one bed.</br></br>It’s gross, and one good reason to keep your feather duster handy.</br></br><strong>Toxic Dust</strong></br></br>Whoa! Toxic <em>dust</em>, you say? Yes, that’s right. <a title="NPR" href="http://www.npr.org/templates/story/story.php?storyId=120252957" target="_blank">That’s a real thing</a>, and the hope is that you’re never exposed to it. The problem, though, is that industrialization makes it more likely every day. Pesticides, industrial waste and toxic gasses leave residue in the soil and air that gets trapped in dust particles that can eventually end up in your home.</br></br>Even worse than gross, it’s potentially dangerous. And, it’s reason number two to wage war on dust.</br></br><strong>Dust Allergens</strong></br></br>Not all dust is toxic, as in toxic waste, but there are <a title="Canadian Centre for Occupational Health and Safety" href="http://www.ccohs.ca/oshanswers/chemicals/lungs_dust.html" target="_blank">many organic allergens</a> floating around in the air that can cause serious lung problems when they accumulate in the dust around your home. Some typical harmful particles come from moldy grain, bird feathers and droppings and, perhaps most commonly, animal dander.</br></br>You’re probably right in assuming that the average dust buildup in your home is harmless enough, but it’s good to keep these things in mind – especially if you notice trouble breathing or more frequent illness.</br></br>And, if you find you don't have the time to bust the dust, you can always <a title="Local Home Cleaners" href="http://porch.com/local/home-cleaners?tid=social_atgstores_~~_~~_~~_~~_~~_~~_~~_~~_~~_~~" target="_blank">find a local housecleaning service at Porch.com</a>.
