This system keeps the exterior wall temperature cooler and drier. For Louisiana climates it seems that it would work that way only with a positive interior pressure pushing the cooler air to the exterior. In fact, it would be easy to reverse the pressure with seasons. Regardless, if the wall is designed correctly, it could be a good filter system. Electrostatic filters are also used to fight electromagnetic pollution which comes in several forms.
Natural air is ionized in equal amounts of positive and negative ions.
Ions increase and decrease with changes in temperature, humidity, winds, the moon, cloudy or clear skies, and they change polarity during thunderstorms, when near waterfalls, and seashores or in the mountains. The electromagnetic pulse, that everything has, does not cycle at the same rate. The body's rhythm and that of the Earth's is pretty much one and the same. When deprived of this natural rhythm, the body becomes weaker. This natural rhythm may be disturbed by steel buildings or electrical currents found in electric blankets or computer terminals.
