NovaUVC™ Ultraviolet Germicidal Irradiation

Ultraviolet Germicidal Irradiation (UVGI) with Dosage Verification

NovaUVC™ for Hospital HVAC

UVGI can protect a hospital's most vulnerable patients. Ultraviolet Germicidal Irradiation (UVGI) or UV-C has been shown to inactivate viruses, bacteria, and fungi. Studies have shown that air-cleaning technologies using ultraviolet C (UV-C) disinfection, also termed Ultraviolet Germicidal Irradiation or UVGI, produce beneficial health effects.1 Airborne contamination comes from a variety of sources and circulates through the HVAC system. ASHRAE has recognized this and has given guidance on usage of ultraviolet C (UV-C) for disinfection.

Evidence on health effects. An extensive body of epidemiological research indicates that death rates, hospital admissions, and asthma exacerbations, as well as other adverse health effects increase with increased concentrations of particles in outdoor air. Because much of a person's exposure to outdoor air particles occurs indoors and because this exposure can be reduced by filtration and disinfection, it is reasonable to expect associated health benefits from particle filtration and disinfection that is effective in removing particles having outdoor origin. 2

Airborne transmission of diseases through HVAC systems is actually much more prevalent than previously thought. Hospital acquired infections are costing healthcare providers large sums and whilst robust cleaning regimes have been adopted, these infections still affect between 10 and 20% of patients and in some cases are fatal.
