You know, when homeowners come to me with concerns about mold, bacteria, or pests in their air ducts, they\u2019re often surprised to learn about a nifty little solution called HVAC UV lights. The idea of blasting your ventilation system with ultraviolet radiation might seem like some sci-fi gimmick, but let me tell you, these things really pack a punch.<\/p>\n

We\u2019ve been utilizing the power of UV-C for years to keep facilities free from unwanted critters and contaminants. It\u2019s a tried-and-true method that hospitals have relied on for decades to maintain a sterile environment. And now, homeowners can harness that same technology to keep their indoor air clean and fresh.<\/p>\n

That said, installing UV coil-sanitizing lights in your HVAC system<\/a> isn\u2019t a magic wand that\u2019ll instantly purify the air in your home. There are a few factors to consider, like the size of your home and the placement of the lights. But when done right, these bad boys can be a game-changer for anyone looking to breathe easier.<\/p>\n

What Are UV Lights?<\/h2>\n

UV lights, or ultraviolet lights, are a type of electromagnetic radiation<\/a> with wavelengths shorter than visible light. While visible light has wavelengths between 400-700 nanometers (nm), UV light falls in the range of 100-400 nm.<\/p>\n

There are three main types of UV light radiation:<\/p>\n

    \n
  1. UV-A (315\u2013400 nm): This has the longest wavelength and is not absorbed by the ozone layer. It\u2019s the type of UV radiation in tanning beds.<\/li>\n
  2. UV-B (280\u2013315 nm): This has a shorter wavelength and can cause sunburns. The ozone layer absorbs some UV-B radiation.<\/li>\n
  3. UV-C (100\u2013280 nm): This has the shortest wavelength and is completely absorbed by the ozone layer and atmosphere. However, it is used in germicidal lamps to kill microorganisms.<\/li>\n<\/ol>\n

    The UV lights used in HVAC systems are UV-C lights designed to act as germicidal lamps. Their short-wavelength rays break down genetic material in bacterial and viral cells, preventing them from multiplying. This makes UV-C very effective at disinfecting air and surfaces from pathogens like mold, mildew, bacteria, and viruses.<\/p>\n

    How UV Lights Clean the Air<\/h2>\n

    Ultraviolet (UV) lights for HVAC systems are electronic air cleaners<\/a> that are commonly known as ultraviolet germicidal irradiation (UVGI) systems. <\/p>\n

    They target a very specific type of air contaminant, namely microorganisms such as bacteria, viruses, and mold spores. <\/p>\n

    You might be familiar with the way hanging laundry out in the sunshine helps kill any germs or mold clinging to it. UV lights work in essentially the same way.<\/p>\n<\/div>\n<\/div>\n
