Description: The Migro HVAC PureAir is the next generation of indoor air quality (IAQ) technology. With increased PhotoCatalytic Oxidation it is capable of purifying every cubic inch of air that the heating, ventilation and air conditioning (HVAC) system reaches without requiring the complicated installation and maintenance of UV Light Systems, literally set it and forget it. It is effective against all three categories of indoor air pollutants: Particulates Microbials Gases Thoroughly tested to safely remove the risks of airborne and surface bacteria, mold spores and viruses, such as MRSA, E-Coli, and Norwalk, to name a few. It also eliminates off-odors from cooking, manufacturing and processing foods. How it works: Installed into the supply plenum of the existing air conditioning or heating system air ducts, the Migro PureAir produces Negative Ions that are distributed through the air handler, through the duct system, and into the conditioned living space. Negative ION gives an extra electron to the free radical. The atom is now neutralized. The chain reaction of free radicals stops here. This reduces your risk of most sickness and disease. Very small particulates such as smoke and atmospheric dust, form clusters that fall out of the air. The clusters are also easily captured in an air filter. The electrical charges cause the molecules of common household odors and VOCs to be neutralized or broken up leaving the air fresh and clean smelling—that same freshness you notice after a thunderstorm! The ions are germicidal! Contact with bacteria and viruses in the air and on surfaces destroys their membranes which disinfects the air.
