Outdoor contaminants such as pollutants and airborne particulates, always seem to find their way into even the cleanest homes. Keeping a home’s interior free of such irritants, including allergens, dust, and pesticides, means leaving contaminated clothing at the door.

In this particular photograph, four pairs of footwear had been left on the front porch so as to not track attached particulates into this house. Note that in this particular instance there is a door matt upon which one can wipe his, or her feet, prior to entering the home.
