Abstract:
A method for treating the atmosphere comprising the steps of:(a) sensing the presence of pollutants in outside ambient air with a pollutant sensing means to generate a signal;(b) providing means for treatment of the outside ambient air based on the signal, wherein the means for treatment of the ambient air comprises:i) a non-airborne substrate selected from the group consisting of outside heat exchanger coils and outside components of air conditioning systems;ii) the substrate having at least one ambient air contacting surface with a pollution treating composition thereon and a means for drawing the outside ambient air into contact with the surface containing the pollution treating composition;(c) activates the means for drawing the outside ambient air into contact with the surface containing the pollution treating composition for converting the pollutants into non-polluting compounds based on the signal to treat the atmosphere; and(d) drawing the ambient stir into contact with the surface containing the pollution treating composition.
