Ultraviolet (UV) light has been used for decades for disinfection and purification purposes. The technology used in most UV air purification systems is ultraviolet germicidal irradiation (UGVI), which uses short-wavelength UV light called UV-C to inactivate harmful microorganisms such as bacteria, viruses, and more. The use of UV light for disinfection and purification purposes started in commercial and municipal purposes, however over the last two decades, UV light air purification products have been extremely popular and safe for use in homes and offices.

Is There a Need to Clean Indoor Air?

It is a common misconception that indoor air is cleaner than outdoor air. Several studies have determined that indoor air pollution can be ten times worse than outdoor air pollution. This is because the contained indoor areas allow the air pollutants to build up more compared to open spaces in the outdoors. Whether it is indoor or outdoor, air pollution can lead to several types of health conditions.

For people who are sensitive to the quality of air, any pollution can b extremely detrimental to their health and wellness. This includes people who are allergic to pollutants, suffer from asthma, or other types of respiratory conditions, eye and vision health issues, and more. Air pollution has adverse effects on the health and wellness of everyone, not just those who are sensitive to air pollution. This makes a strong case of getting an air purification system that can clean the air inside your home and office.

Purification by UV Light

UV light has properties that allow it to inactivate mold, bacteria, viruses, and other pathogens. The sun emits three types of UV light: UC-A, UV-B, and UV-C. The UV-C does not reach as it gets absorbed by the ozone layer in the atmosphere. Although any prolonged direct exposure to UV-C can be dangerous for humans, this type of UV light is highly effective in killing air pollutants.

The use of UV light for disinfection and sterilization was initially used for water sterilization and medication sanitation purposes. UV light is invisible to the human eye and does not contain any chemicals. This makes UV light a chemical-free and highly effective way to clean air and other elements. The unique disinfecting characteristics of UV light comes from its wavelength provides it with its germicidal properties. When air pollutants are exposed to UV light, the pollutants are rendered incapable of reproducing or infecting.

Integration With HVAC System

There are different types of indoor air purification systems including systems that use filters, UV lamps, and stand-alone systems. The systems that integrate with the HVAC system can also have filters installed for a complete air purification environment. The filter system typically has high-efficiency particulate air (HEPA) filters that provide excellent protection against smaller-sized particles.

The UV air purification systems use a single or dual UV lamp installed in the ductwork or near the evaporation of the HVAC system. As air passes through the ductwork, the UV light from these lamps kills or inactive the pollutants. These lamps are designed to emit UV-C light which has the most energy compared to other types of UV lights. UV light does not add any chemicals to the air and is considered safe for an air purification system.

Ozone can be a byproduct of UV lamps. To counter this issue, there are some indoor air purification systems that use mercury vapor bulbs that can neutralize any ozone that is being generated, which can be harmful to the respiratory system. A professional HVAC technician who is experienced in air purification systems can guide you on the right type of system for your home or office.
