Ultraviolet (UV) lights for Sale

In summary, studies of the health benefits of applying UVGI systems have inconsistent results. Also, there have been very few studies of UVGI in HVAC systems outside of health care facilities. The evidence of potential health benefits is sufficient to warrant further research. UVGI appears to be more likely to reduce respiratory infections when applied in crowded spaces and when there are few opportunities for infection away from the spaces containing the ultraviolet equipment.

UVGI has been installed in occupied rooms in a manner that causes air near the ceiling to be irradiated, these are sometimes called upper room air UVGI systems. The systems are designed so that little of the UV light penetrates into the occupied portion of the room. The purpose of these systems is to kill or deactivate the bacteria and viruses within small airborne particles that sometimes cause infectious diseases. Thus, these systems are used to reduce rates of airborne transmission of respiratory infections, infections of wounds, and infections at the sites of surgery. This review will not consider the effectiveness of UVGI in reducing infections of wounds or surgical sites.
