UV HVAC Systems for Hospitals and Homes


Ultraviolet light is a powerful disinfectant, sterilizing surfaces, water and air in many environments.  The power of UVC radiation was discovered decades ago and UVC lamps are now found in many sterilization applications, providing quick, effective and cost-efficient sterilization solutions.  The ability for UV light to kill pathogens in air and water was proven scientifically early in the 20th century.  UV lamps have been used in air treatment systems in hospitals since the 1930’s to prevent the spread of diseases including tuberculosis and measles. 

UVC Lamps Kill Many Viruses and Bacteria

UVC lamps replicate the powerful UV electromagnetic radiation from the sun, proven to eliminate harmful viruses, bacteria and pathogens in air and surface sterilization systems.  UVC germicidal lamps are proven to be effective against many types of viruses including influenza (flu), rhinoviruses (common cold), severe acute respiratory syndrome (SARS) and the novel coronavirus (COVID-19).   UV light also eliminates bacteria such as many variations of Streptococcus including Staphylococcus aureus (Staph infection). 

UVC lamps, when properly installed in HVAC systems, are known to prevent the spread of airborne illnesses by destroying viruses on contact.  UV HVAC systems are also known as ultraviolet germicidal irradiation (UVGI) systems and target air contaminants like viruses, bacteria and mold spores.  UV light has the ability to penetrate the DNA of these living organisms and render them unable to replicate which leaves them harmless. 

Commercial and Residential Benefits of UV Lamps in HVAC Systems 

Hospitals and many commercial and industrial applications have been using UV air sterilization systems for decades to disinfect potentially dangerous environments.  UV HVAC systems used in hospitals help to prevent the spread of airborne illnesses in patient rooms, operating rooms and common areas.  UV lamps can be installed in the main HVAC unit aimed at the coils to prevent the spread of contaminants through your heating and cooling system as well as in air ducts.  Stand alone units can be placed in patient bathrooms for further protection in areas known to spread bacteria and viruses. 

UV HVAC systems are becoming more popular in residential homes as many people become aware of the benefits and the ease in which you can disinfect the air in your home.  This is very beneficial to people with compromised immune systems or underlying health conditions, especially respiratory illnesses like asthma.

post 95

Ultraviolet light has long been known to provide powerful disinfecting properties and is now more than ever a hot topic to sterilize hospitals, operating rooms and medical equipment.  Hospital acquired infections (HAIs) are a real concern, especially in the midst of a global pandemic where hospitals are treating highly contagious people with serious disease.  Cleaning and sterilizing hospital rooms and equipment is critical to prevent the spread of disease through airborne viruses and contaminated surfaces. 

UV Light Kills Viruses on Surfaces

UV light is proven to kill viruses, bacteria and airborne contaminants when using UVC germicidal lamps for air treatment systems, designed to emit the proper wavelength of light.  UV light from the sun is emitted in UVA, UVB or UVC wavelengths, with UVC being the most powerful form of germicidal electromagnetic radiation.  UVC light from the sun is mostly absorbed by the ozone layer, although scientists and lighting specialists have designed UVC lamps which mimic the powerful, germ-killing wavelengths.  

UVC germicidal lamps are used in UV surface sterilization equipment to treat hospital equipment, surfaces, beds and entire hospital rooms.  Scientists have even developed robots which roam through a hospital room and effectively eliminate bacteria and viruses on contact.  According to this article in Hospital News, UVC light emitted at the right wavelength can kill the MRSA bacteria in 1.2 minutes at a 5 ft. distance.  Hospitals use UVC disinfection in many types of surface sterilization equipment including portable units and UV germicidal robots.
