Ultraviolet (UV) light is a great way to eliminate potentially hazardous compounds, such as mold and bacteria, from the air in your home. But it's essential to understand the risks of UV light and how to use it safely. In this article, we'll discuss the cost of installing UV lights in an HVAC system, the advantages of using UVGI systems, and the best way to use UV lights in your home. The expense of installing UV lights in an HVAC system depends on the type of lights you select and whether or not a HVAC professional installs them.
UVGI systems generate the same ultraviolet light that is present in sunlight, and are promoted to “disinfect” indoor air and air conditioning equipment. Even with UV lights in the air conditioning unit, air filters are still necessary to remove particulates, such as dust and dandruff, from the air before they circulate around the house. The air disinfectant lights are placed in the ventilation grilles, which are part of the ducts of the central air conditioning system. To work its magic, UV light has to be correctly installed in the air conditioning system (and UV lights can damage your eyes if you're not careful).
It is the UV-C section of the spectrum that has germicidal properties, since 253.7 nm is the ideal frequency level at which DNA absorbs the most UV light. Since UV lamps only really work to keep the drain pan and the coils free of mold and bacteria, let's compare the cost of each of them to determine what offers the best value for money, particularly since both achieve the same result. You should seriously consider installing a built-in UV air purifier if you or your family have allergies or respiratory issues. If you only feel like you're sneezing but have no other symptoms, dust or dandruff could be the real cause of the problem, and unfortunately, UV lights can't fix those issues. Researchers know that the virus travels in the form of water particles suspended in the air, so only UV lights installed in the ducts that treat airflow could be useful. As air circulates around the house, it carries germs and allergens with it, which eventually pass through ultraviolet light, which disinfects the air as it recirculates around the house.
One study found that UV lights could reduce the amount of mold and bacteria in a test home by 97%.Finally, some heating, ventilation, and air conditioning technicians rely on UV light treatment in their system because it can kill bacteria.
