The technology in your PIONAIR System uses photocatalysis, which is designed to oxidize organic odors, germs, and fungi in an average room or office as rated on the module in use ( 350 sq. ft., 750 sq. ft., 1500 sq. ft., or Commercial.) Natural air purification is performed by the UV light rays of the sun and ozone, which is produced by thunderstorms. This is why air smells so fresh after a thunderstorm. Ion generation occurs in nature from lightning and ultraviolet radiation.

What are Ions and How Do They Work?

lons occur naturally in nature. Ions are electrically charged particles that are positive or negative. There is a “natural balance” maintained by nature. The ratio is approximately 6 positive ions to 5 negative ions. Indoors, this ratio is off balance because of the abundance of positive ions and the lack of negative ions.

This disruption of the natural balance is primarily caused by building materials used in the structures in which we spend 90% of our time. The negative ion gives up its charge to the pollutants such as dust, pollen, bacteria, smoke, and formaldehyde. This new negative particle attracts positive particles until they become heavy enough to fall out of the air we breathe. This process is called “agglomeration”. Your PIONAIRâ„¢ unit produces negative ions, duplicating this natural process, thereby reducing these and other particles in the air.
