Studies have shown that negative ions stimulate the body s ability to absorb oxygen. With a good quality HEPA or Ultra Filter. Next would be a good quality ion generator. UV light and ozone combined to create a catalytic oxidation is by far the most efficient. Ozone Catalytic Oxidation and carbon.
Some molds produce compounds that can make even the non-allergic ill.
They each have their abilities and as such work best when used together as in catalytic oxidation. Corona Discharge ozone generators are designed for use with oxygen or dried air. When room air is used without a dryer or oxygen generator, the moisture in the air creates nitric acid or nitric oxide, which causes an extremely corrosive atmosphere and actually creates an air pollutant nitric oxide gas. This problem could be eliminated by using an air dryer or oxygen generator. However, this adds considerably to the price, and no room air systems use this expensive air pretreatment.
