How UV Lights Improve Air Quality and Prevent Airborne Disease

How UV Lights Improve Air Quality and Prevent Airborne DiseaseHealthy indoor air quality is more than just removing inorganic particulates like dust and lint. 

Living microorganisms that occupy our household airspace also pose a threat to the indoor environment. Many of these microbes are too small to effectively filter out of the air. Some airborne microorganisms actually infect the HVAC air filter media and multiply there, spreading contamination into the system airflow.  When confined inside an enclosed structure like a home, toxic airborne microbes may accumulate to levels that exceed exposure elsewhere, including outdoors. Daily doses with every breath you take inside your home may increase the likelihood of allergic reactions and illness.

Killing rather than capturing microorganisms is the preferred option to eliminate infected air. The anti-microbial properties of ultraviolet (UV) light have been utilized for over 100 years to sterilize air and surfaces in hospitals and other facilities. A component of natural sunlight, UV light wavelengths destroy the reproductive capacity of viruses, bacteria, mold spores and pollen without posing any health threat to humans. When these microorganisms cannot multiply, the contamination dies out rapidly.

Here are two ways ultraviolet lights can safeguard the breathing air inside your home.

  • A UV light array can be installed inside the supply duct of your HVAC system. As air constantly circulates through the ductwork, it is directly exposed to the disinfecting power of ultraviolet light rays. About the size of a mini fluorescent tube, the light can be installed through a small hole in the duct by a qualified HVAC technician.
  • A dedicated UV light may also be placed at the evaporator coil inside the indoor air handler. The coil is often damp and becomes a frequent location for toxic mold growth which, in turn, contaminates the system airflow with airborne spores. Continuous exposure with ultraviolet light destroys mold growth inside coil passageways and eliminates a common source of tainted air quality.

Since 1922, Paitson Bros. has offered effective solutions to improve indoor air quality. Contact us for more information about the benefits of UV light technology.
