UV lights have been found to be very effective in reducing microbial growth within your HVAC system. In fact, the Nobel Prize in Medicine was awarded to Niels Ryberg Finsen in 1903 for his work using ultraviolet light radiation to cure skin infections. Ultraviolet (UV) lights for air conditioning systems are commonly known as ultraviolet germicidal irradiation (UVGI) systems. They target a very specific type of air pollutant, namely microorganisms such as bacteria, viruses and spores of mold.
You may be familiar with how hanging clothes in sunlight helps kill any germs or molds that adhere to them. UV lights essentially work the same way. Mold and bacteria are annoying intruders that ruin indoor air quality. Germs that are in the air pass through the filter of the HVAC system and circulate through your home or business.
The inner coil of your air conditioning system is part of what cools your home, but it can also be a hotbed of microscopic misery affecting air quality and system efficiency. Numerous health studies have shown that UV lights in heating, ventilation and air conditioning systems help eliminate bacteria and allergens that accumulate in the system. If you're thinking about installing a UV HVAC lamp, talk to a heating and cooling technician first. UV HVAC lights have many advantages, from reducing allergies and energy costs to preventing common air conditioning damage.
Since UV lights only kill germs when the device is turned on, run the system for a few hours after installation. UV light bulbs work less effectively when they're covered in dust, so you'll need to clean them quite often to ensure this never happens, about once every two months, and possibly more if you live in a particularly dusty place. With the right conditions and proper installation, UV lights can be very effective in killing viruses, molds and bacteria. Even with UV lights on the air conditioning unit, air filters are still necessary to remove particles such as dust and dander from the air before it circulates around the house.
The cost of installing UV lights in an HVAC system depends on the type of lights you choose and whether or not an HVAC professional installs them. However, installing an HVAC UV air purifier could be a proactive step for those living in humid and humid climates. Installing a UV HVAC lamp benefits everyone in your household, especially people with allergies and respiratory problems. In addition, before you start looking for a UV HVAC lighting system, you will have to choose which of the two available types best suits your needs.
According to manufacturers of UV lighting systems, UV light destroys harmful microorganisms, including mold, fungi, bacteria and viruses. The extra expense may be worth it if you're suffering from problems that UV lights can solve, such as mold caused by excess moisture and humidity; otherwise, you'd better look for another, more affordable solution. Since less mold and mildew circulate through the air conditioning system thanks to an ultraviolet light unit, drain pipes are also less likely to clog, one of the most common air conditioning problems. You should seriously consider installing a UV air purifier built into the ducts when you or your family suffer from allergies or respiratory problems.
It is the UV-C section of the spectrum that has germicidal properties, with 253.7 nm being the ideal frequency level at which DNA absorbs the greatest amount of UV light.
