PureAir air purifiers clean the air in 2 ways, inside and outside of the unit. Air inside the purification chamber is exposed to intense germicidal UV (UVGI) light that produces a purifying plasma. This destroys bacteria, fungi, viruses, and other pollutants (including unpleasant odors). This ‘ultra-pure’ air then carries the purifying plasma and its purifying results to the air and surfaces throughout your home or office. See the Technology section for more details on the synergistic components of this purification process.
