Reduction of Formaldehyde, Ammonia, SO₂, and CO₂ Concentrations in Room Air

Analyses by the writer indicated that complex electrical fields could modify perceived odor and participate distribution. In subsequent experimentation, this was found to be the case. A complementary experiment was undertaken to gather information on the influence of in-duct complex electrical fields on the concentration of several gases: formaldehyde, ammonia, sulphur dioxide, and carbon dioxide. It was found that the complex electrical field reduced each, as compared to controls. The reductions, depending on the gas, ranged up to 49 percent. The strong effect on formaldehyde is of potential practical significance due to its possible human carcinogenicity.
