Ultraviolet (UV) light is a powerful tool for cleaning the air that circulates through your home's ducts. Studies have shown that UV light energy produced by bulbs can destroy the smallest particles of dust, making the air cleaner and healthier. In fact, one study found that UV lights could reduce the amount of mold and bacteria in a test home by 97%. Another study showed that air purifiers with ultraviolet light could reduce the amount of flu virus in the air by 90%.
Installing a UV HVAC lamp can benefit everyone in your home, especially those with allergies and respiratory problems. When it comes to improving indoor air quality, UV lights on the air conditioning system are an effective solution. Most bacteria, mold spores, and viruses in the air pass easily through UV light without being affected. However, UV lights only really work to keep the drain tray and coils free of mold and bacteria. If you're just sneezing but don't have other symptoms, dust or dandruff could be the real cause of the problem, and unfortunately, UV lights can't fix those issues. In addition to air purifiers, another way to improve indoor air quality is to install UV lights on the air conditioning system.
Unlike coil sterilizer lights that point at the air controller coil to sterilize anything in it, this UV light system removes harmful compounds from moving air. UV light doesn't immediately kill organisms, but it makes them unable to produce the proteins they need to survive and reproduce. UV air purifiers use UV-C light (a wavelength of light of 254 nanometers) that is absorbed by the DNA of microorganisms. The cost of installing UV lights in an air conditioning system depends on the type of lights you choose and whether an HVAC professional installs them or not. However, if you or your family has allergies or illnesses caused by germs or particles that no other tool can remedy, then UV HVAC lights are worth it.
Researchers know that the virus travels in water particles suspended in the air, so only UV lights installed in the ducts that treat the air that circulates through them could be useful. UV HVAC lights purify the air that circulates through the HVAC system and eliminate contaminants such as bacteria and germs. Coil sterilization is the most common type of UV light for HVAC systems because it is less expensive than air sterilization and is similarly effective.
