No matter what part of the country you reside in, your indoor air quality can be worse than that of the quality outdoors. When you live somewhere like Utah, that becomes an even bigger problem—due to something called an inversion.
Wintertime inversions are a common occurrence here, and happen when normal atmospheric conditions become inverted, trapping a dense layer of cold air under a layer of warm air, and along with it trapping pollutants. As can be expected, this makes the air outdoors and within your home very unhealthy—particularly if you are not equipped with the right indoor air quality products.
