Hard Surface vs. Soft Surface
- A hard surface floor does not trap and hold dirt
- A soft surface floor/carpet does trap and hold the dirt.
- A carpet can hold its own weight in dirt and still look good, i.e. 2 pounds of dirt in a 30 oz./sq.yd.
- A carpet can hold 2 times its weight in dirt before people begin to notice, i.e. 4 pounds of dirt in a 30 oz./sq.yd.
- 90% of the dirt that gets on a carpet in a building is tracked on by people's shoes, from inside or outside hard surfaces. Airborne dirt and dust makes up the other 10%, coming in through windows, doors, airborne cooking grease and the HVAC system
