Nature's way of purifying the air is through the generation of positive and negative ions. Air ions occur naturally when an energy source is presented in the atmosphere. This happens as a result of water-falls, lightening storms, ocean surf, and sunlight.

These charged oxygen molecules O2+and O2- are highly active, and when reacting with airborne water molecules, H2O2 (Hydrogen Peroxide) is formed. A chemical reaction occurs, and oxidants break down the protein structure of pollutants, rendering them harmless.

The Hygieia device generates these same positive and negative ions - just like those found in nature that purify and freshen indoor air by eliminating the harmful pollutants mentioned above.
