Notice the CO concentration and the Effective Operating Zone with air exchange. The CO cloud is still concentrated
in a small area. Note the "Dividing Zone" shown above, this is the line where airflow changes direction. In Model 2, air
changes are cut in ½ as little or no CO crosses the Dividing Zone to be exhausted.

Notice the CO concentration and the Effective Operating Zone (Expanded through the Dividing zone to the second
vent) with air exchange and forced air mixing through the dividing Zone. The CO cloud is diluted with the available air in
the building. Note the "Dividing Zone" shown above, this is the line where airflow changes direction. In Model 4, air
changes are full as forced air mixing has moved and mixed the CO between all air zones.
