IUVA Releases Fact Sheet on UV Disinfection for COVID-19

The International Ultraviolet Association (IUVA) believes that UV disinfection technologies can play a role in a multiple barrier approach to reducing the transmission of the virus causing COVID-19, SARS-CoV-2, based on current disinfection data and empirical evidence. UV is a known disinfectant for air, water and surfaces that can help to mitigate the risk of […]

Can UVC help prevent COVID-19 transmission by reducing contamination?

Based on existing evidence, we believe so. Here’s why: UVC light has been used extensively for more than 40 years in disinfecting drinking water, waste water, air, pharmaceutical products, and surfaces against a whole suite of human pathogens (Fluence UV Dose Required review IUVA). All bacteria and viruses tested to date (many hundreds over the […]

Can Novel Coronavirus Live on Smartphone Screens?

The novel coronavirus that causes Covid-19 is a close relative of SARS and likely, but without certainty, may have a similar lifespan on surfaces. These estimates come from data collected during the 2003 SARS outbreak and reported to the World Health Organization. The two viruses are genetic cousins: Both infect our airways, have a single strand […]

UV-C And Hospital Infection Control

Each year, more than two million people contract a hospital-acquired infection (HAI) that can also be antibiotic-resistant. In 2013, these infections resulted in at least 23,000 deaths (CDC). In fact, HAIs kill more people than AIDS, breast cancer, and auto accidents combined. Emerging diseases — such as Sudden Acute Respiratory Syndrome (SARS) and Middle East […]

Killing Airborne Germs with Ultraviolet Germicidal Irradiation

As the threat of COVID-19 and other infectious diseases continue to make headlines, more and more building and facility managers are searching for ways to reduce the threat from contagious airborne pathogens. Using ultraviolet germicidal irradiation (UVGI) for disinfection is not new. In 1877, researchers in the journal Nature described how sunlight prohibited the growth of microorganisms. […]

UV-C energy and HVAC applications

Light energy in the ultraviolet-C (UV-C) wavelength has been used extensively in HVAC equipment since the mid-1990s to improve indoor air quality (IAQ) by eliminating the buildup of biofilms and other organic contaminants on the surfaces of system components, including cooling coils, plenum interiors, drain pans, and air filters. UV-C works by disassociating elemental bonds, […]
