UV Systems Effectively Improve Indoor Air Quality

How You Can Use UV Systems to Effectively Improve Indoor Air Quality

Study reports UV-C inactivates microorganisms with a kill ratio of 90 percent or higher

Ultraviolet (UV) light has been growing as part of the HVAC landscape for years, especially for improving Indoor Air Quality. As the technology has matured over time, organizations have undertaken studies and research to prove its effectiveness. Recent studies have found that UV Systems Effectively Improve Indoor Air Quality  by by eliminating harmful germs from the air, HVAC air ducts and evaporator coils.

One such organization, ASHRAE, recently weighed in on the benefits of UV light by “recognizing the health benefits of UV-C as demonstrated by several studies. The technology is a potentially beneficial option that building owners should consider installing.”

The UV-C wavelength inactivates microorganisms living on HVAC air ducts and evaporator coils with a kill ratio of 90 percent or higher, depending on light intensity, length of exposure, lamp placement, and lamp life cycle. The technology removes both bacterial and viral aerosols from the air.

Tangible health benefits showing that UV Systems Effectively Improve Indoor Air Quality found by the ASHRAE research committee:

• Several studies have examined the health benefits of using UV-C lamps to decontaminate the airstreams in health care facilities. Some have concluded that, by eliminating harmful germs from the air, UV-C can protect a hospital’s most vulnerable patients from getting sick;

• UV-C has been found to be effective in eliminating fungus growing in HVAC systems. Rampant fungus can contribute to hypersensitivity pneumonitis, allergic rhinitis, and asthma; and
