This is not a new technology:  Ultraviolet light has been used since the
1930’s in a variety of industries including surgical instrument sterilization,
food packaging and processing, post offices, hot tubs, restaurants and
water purification.
          The ultraviolet light ray breaks through the cell wall of the organism
and destroys the DNA. This renders the organism unable to reproduce
and cause illness. For example, when someone has a virus or a cold
and coughs or sneezes in one room; those germs are spread to every
room in the house, through the ventilation system, within 30 minutes.
With a BreatheCLEAN purifier attached to the ventilation system, those
germs are destroyed and can not cause illness or irritate
asthma or allergies.
