Indoor Air Protection with UV Sterilization Lamps

Indoor air quality (IAQ) is an important consideration related to the comfort and health of building occupants. IAQ is affected by the quality of air in and around buildings with airborne contaminants existing both inside and outside. Controlling pollutants inside will help to reduce risk and improve the quality of indoor air for greater health and well-being. 

Airborne contaminants that exist both inside and outside of buildings include:

• Indoor pollutants:

• Wood burning stoves

• Tobacco smoke

• Cooking

• Ozone and chemical emissions from cleaning solvents, electronic equipment and human metabolic byproducts

• Outdoor pollutants:

• Agricultural and farming

• Vehicle exhaust

• Waste management facilities

• Chemical storage areas

• Processing equipment emissions

• Combustion byproducts during manufacturing

UV Air Purifier in HVAC Systems

HVAC systems can be a great source of air pollution if dirt accumulates in the ventilation system. Dirt combined with moisture and poor management of condensation can create serious air quality problems due to biological growth. This typically occurs due to problems with the cooling coil condensation, humidifiers and other sources of moisture, poor maintenance of filters and inadequate particle filtration.

Air contaminants may be either biological, gaseous or particulate. Methods of improving air quality include eliminating the source of emissions, capturing emissions at the source with exhaust, dilution, increased ventilation, filtration and air sterilization. Of these methods, the only one that actually eliminates biological contaminants is air sterilization. HEPA filters effectively filter particles as small as .3 microns, although they are ineffective against volatile organic compounds (VOCs) present on a molecular scale.

UV air sterilization is proven to eliminate VOCs and microorganisms such as bacteria, viruses, mold and fungal spores and many other air contaminants. In-duct UV air purification systems installed near the cooling coils of HVAC units prevent microbial growth on cooling coils, thus preventing the spread of these contaminants throughout the home, office or building.

Reduce Airborne Infections in Hospitals with UV HVAC Systems

Hospital stays may create additional illnesses for people already seeking treatment for health conditions.  The Center for Disease Control (CDC) estimates that nearly 1 in 25 patients acquire an additional infection contracted from a hospital stay.  These healthcare acquired infections (HAIs) pose a real threat to those with vulnerable health conditions and may literally be a matter of life or death.  It is estimated that nearly 100,000 people die each year in the U.S. due to an HAI.

Stagnant air in healthcare facilities and hospitals create a breeding ground for viruses and bacteria to reproduce.  Harmful airborne pathogens can quickly become a source of infection to patients and hospital staff.  Hospitals can drastically reduce the risk of airborne infections with a UVC germicidal HVAC system.  By installing UVC sterilization lamps in air flow systems these harmful microorganisms are instantly eliminated before they have a chance to infect patients and staff.

How Do UVC Germicidal HVAC Systems Work? 

UV light emitted in the UVC wavelength, specifically at 254 nm or 185 nm for ozone production effectively eliminates harmful pathogens as they pass through the UV air sterilization system.  UVC radiation quickly penetrates the cells of these infectious airborne microbes to render them non-viable and unable to reproduce.  UVC germicidal lamps are proven highly effective on even the most stubborn, drug resistance pathogens such as MRSA, strep, hepatitis, tuberculosis, vancomycin-resistant enterococci (VRE), C. difficile and many other infectious microorganisms.

Hospitals that incorporate UV light technology to sterilize rooms in addition to their regular cleaning routines will provide many benefits to patients, staff and to the hospital. Hospital acquired infections are more common than many people realize with about 1 in 25 people contracting an infection due to a hospital stay.  This can be devastating for the patient and lead to longer hospital stays. 
UVC radiation is proven to effectively kill almost all forms of harmful pathogens including superbugs like Methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant enterococci (VRE).  UVC robots are even shown to effectively kill these resistant superbugs when in the line of sight and also when the virus is hiding behind objects at a rate of 99.9%. 
The success of UVC robots depends entirely on the quality of the UVC sterilization lamps on the unit.  Using high quality UVC lamps is key to realizing maximum benefit and germ killing effectiveness.
