The Efficacy of UVC in HVAC Systems

The Efficacy of UVC in HVAC Systems

Ultraviolet Germicidal Irradiation (UVGI) in Hospital HVAC Decreases Ventilator Associated Pneumonia

Hospital Acquired Infections (HAIs) constitute a major health threat impacting millions of people globally, and increase patient morbidity and mortality with an economic impact of up to $45 billion in the US alone. Gram negative bacteria are of particular concern, are responsible for more than 30% of all HAIs and are becoming increasingly multi-drug resistant. These universal health concerns surrounding HAIs have driven organizations such as ASHRAE to investigate reservoirs of pathogenic microorganisms and the role of the HVAC in the amplification and transmission of HAIs. (ASHRAE HVAC Design Manual for Hospitals and Clinics). 

Improving Environmental Hygiene: Shining the Light on Air Systems to Cut Infections (Becker's Clinical Quality and Infection Control)

HVAC systems have been shown to collect, amplify and spread microorganisms such as Aspergillus, Pseudomonas, Enterobacter and Acinetobacter that cause HAIs and increase patient morbidity and mortality. Implementing germicidal ultraviolet light in HVAC systems at the AC coil can eliminate these microorganisms and reduce health-care-associated infections, leading to significant reduction of non-reimbursable hospital charges.
