How do negative ions and ozone work?
Negative ions are negatively-charged electrical particles that are magnetically attracted to allergens and other airborne contaminates, which are positively-charged. The newly-formed larger particles are then able to fall harmlessly to the ground, and out of the air we breathe. Ozone oxidizes (burns) pollutants, destroying them altogether. The ozone molecule (O3) is highly reactive, so whenever it encounters a floating particulate, one of the oxygen atoms breaks away to oxidize the pollutant. This leaves behind O2 (pure oxygen), refreshing the air even more. Ozone has the 2nd highest oxidation potential out of all the elements.
