Using proprietary UV technology, the Sanuvox In-Duct Ultraviolet Air Sterilization System is designed to maximize exposure time between the air and the UV germicidal energy. The UV system delivers the optimal UV dosage penetrating the cell embrane destroying the DNA structure of the virus.

Installed into the ventilation system, unit achieved, on a single pass with no recirculation, 99.97% destruction of S. marcescens bacteria, 99% destruction of the MS2 virus, and 93% destruction of B. atrophaeus bacterial spore.

McGill University in Montreal Canada has tested the Sanuvox portable / standalone UV Air Sterilization unit (P900GX) against tuberculosis, and achieved a destruction rate of 90% while operating in the sputum induction room of the Montreal Chest Hospital. Sanuvox testing which has been completed by the US EPA, NHSRC and McGill University on bio-contaminants which require up to ten times (10X) the dosage of UV energy to destroy in comparison to the weaker influenza virus.

In a 2003 report titled, Transmission of Influenza, Implications for Control in Health Care Settings1, three modes of transmission relevant to influenza are described. These include contact, droplet, and airborne. Airborne transmission entails the production of infectious droplet nuclei, generally <5 μm in diameter, which, in contrast to droplets, can remain suspended in the air and be disseminated by air currents in a room or through a facility to be inhaled by a susceptible host. Preventing the spread of droplet nuclei requires the use of special air handling and ventilation procedures."
