The quality of indoor air can be up to 10 times worse than outdoor air quality. Some common pollutants in the air include pollen, dust, bacteria, viruses, and other forms of microorganisms. Ultraviolet (UV) light has chemical properties that allow it to inactivate several types of harmful pollutants. When installed in the HVAC system or used as a standalone system, a UV light air purification system can clean the air inside your home, allowing you and your family to breathe cleaner and healthier air. Here is a look at how UV indoor air purification systems work.

What Makes UV Light Inactivate Pollutants?

UV light is a chemical-free way to kill bacteria, mold, and other forms of pollutants. For decades, UV light solutions have been used for disinfection purposes. The UV light solutions are designed to provide UV-C type radiation. It is one of three types of UV radiations emitted by the sun. The other two types are UV-A and UV-B radiations. The UV-C type light from the sun does not reach us, as it is completely absorbed by the Earth’s atmosphere.

UV light is made of small protons that vibrate at a certain wavelength and frequency. The type of UV light that has the highest energy is the UV-C type, which is commonly used in UV air purification systems, in which the particles of the UV light bombard the molecules of the pollutants, damaging the DNA of the pollutant. Without a functional DNA, the pollutants are not able to perform vital cellular functions, rendering them harmless.

Is There a Need to Clean Indoor Air?

Cleaning indoor air is not only important for people who are sensitive to air quality, such as asthma patients, but all humans need to breathe clean air. There are several types of cancers and infections that are linked to poor air quality. Any pollutants in the air can reduce oxygen levels in the body, leading to several types of issues, including fatigue and poor quality of sleep.

Indoor air pollutants need open windows and doors to come inside. Certain pollutants such as radon can come in through cracks and other types of small openings in the house. You might think your indoor air quality is clean because most types of pollutants are not visible to the naked eye. Equipment that can measure air quality indoors is expensive and not easily available. You can check the air quality of your city through certain apps and websites, but keep in mind that indoor air quality is expected to be much worse than outdoors.

How Do UV Air Purifiers Work?

UV light purification systems that integrate with the HVAC system are more common than standalone air purifiers. UV light purification solutions can be combined with high-efficiency airborne particles (HEPA) filters to achieve a higher level of protection from air pollutants. While UV light is highly effective against microorganisms, the HEPA filter provides better protection against finer air pollutants. Make sure to get the HEPA filter changed on time to keep it functioning properly.

The UV light solutions are typically installed in the ductwork of the HVAC system, allowing the air that flows through the system to be cleaned as it recirculates through the unit. The UV air purification system features lamps with UV-emitting bulbs.

There is a potential risk of producing ozone with UV air purification systems, but this can risk can easily be minimized by the use of mercury vapor lamps. Ozone can be harmful since it can cause inflammation in the lungs, leading to different types of health conditions. The reason why ozone can be created in a UV light system is that the UV light can collide with oxygen molecules, leading to the oxygen molecule splitting into two pieces, which can then combine with other oxygen items to form ozone. Consult with an HVAC technician to guide you on the best type of UV air purification system for your home or office.
