How To Selection The Best Air Filter

What dust is made of and why you should do something about it
Many people don’t realize that dust is made up of dead skin cells, dust mite droppings and dust mite body fragments. With dead skin cells acting as a key component of dust, increased time spent indoors may actually contribute to an increase of dust in your home.
As dust accumulates, it becomes more visible to the naked eye, but that doesn’t mean it hasn’t been there the entire time. (Source: Lung.org)
