Whole Home UV Purification

Indoor air quality is an essential aspect of a healthy indoor environment. UV purification helps you stay healthy by sanitizing the air moving through your HVAC system, inhibiting microbial growth from circulating through the air you breathe. If you or someone in your family has respiratory issues, such as allergies or asthma, you know how important it is to have good indoor air quality. By installing a UV Whole Home Air Purifier, you can eliminate mold and mildew, kill viruses and bacteria, and reduce odors, all of which will improve the quality of your indoor air.

What Is UV Purification?

An ultraviolet (UV) light emits powerful rays of energy that kill bacteria, fungi, and viruses. They are commonly used in both home and commercial spaces. UV lights increase the efficiency of your HVAC. The UV lamps will clean the coils and air that passes through the HVAC system naturally.

UV technology has been in use by medical professionals for over a hundred years. In the 1930s, hospitals used these lights to treat conditions like tuberculosis. There are three types of UV radiation: UVA, UVB, and UVC.

The third variety, UVC, is used in HVAC lights. UVC rays have the highest energy, the only rays powerful enough to kill microscopic germs. In an In-Duct UVC system, the UV-C light disinfects the air as it cycles through the return ducts. Enhancing the reflective surface within that section of the ductwork maximizes the UV-C light in all directions, making it more efficient.

How Does UV Air Purification Work?

UV light for HVAC systems is installed either in your air handler or in your ductwork. When germs move through the central air system, they eventually make it to the sanitizing light.

Once the germs are exposed to the light, they absorb the light’s UV rays. The UV rays disrupt the DNA of the germ. When bacteria or mold’s DNA is damaged, it will either die or become unable to reproduce.

There are two varieties of UV sanitizer lights. Coil sanitizer UV lights that are installed near your evaporator coil. A whole home UV sanitizer is installed above your furnace in the duct. This allows the air that flows through your furnace and into your air duct system to be sanitized before ultimately circulating through the air you breathe.

What UV Light Works Best?

Double Bulb UV Light

Single and double-bulb UV lights are installed above or near the furnace. Single-bulb UV lights use around 24V, while double bulb uses around 120V. These two lights are effective in inhibiting microbial growth from your coils, however, the more intense the UV light is, the more area it covers.

The Whole Home air scrubber is installed within the air ducts above your furnace. Because this UV light uses a higher voltage, it allows for more, stronger coverage and purifies the air as it passes from the furnace and into the air duct system. The purified air passes through the supply vents, circulating through the air you breathe, helping you create a healthy indoor environment.

The better UV air purifier is whatever works best for your needs and your budget. For more information, go to our UV Whole Home page to read about the UV air purifier we offer.

How Long Do The Bulbs Last?

The bulbs in a single, double, and even a whole home air purifier can last for up to around 6-12 months. It is imperative to continue the required maintenance to assure that your UV lights are at maximum efficiency by contacting a Fresh Air Matters representative. When the bulb needs to be replaced, a Fresh Air Matters technician is available.
