UV lights or the Ultra Violet lights are a double edge sword. On the one hand, these lights are a highly effective sanitization and decontamination tool. On the other hand, to us humans, its prolonged exposure can cause problems like skin ailments and cancer. To minimize risk to humanity, artificial UV lights are used to kill the bacteria and germs on the surfaces and in the air. These lights are used in such a clever manner that there is no exposure to the people using them.
Germicidal UV lights are being used increasingly to disinfect the air in both homes and other indoor spaces. According To EPA (Environmental Protection Agency), poor indoor air quality happens to be one of the top five environmental threats that mankind is dealing with today. Hence, sanitizing the air in your home with UV Lights is the most viable and quick solution.
What Is Ultra Violet Light?
UV light is a form of electromagnetic radiation. Naturally, electromagnetic radiation is emitted by the sun. It spreads in waves or particles at various wavelengths and frequencies. The broad range of wavelengths is commonly referred to as the electromagnetic (EM) spectrum. This spectrum is split into seven regions. The division occurs in order of diminishing wavelength and expanding energy and frequency. The common nomenclature of the 7 regions is
1. Radio waves,
3. Infrared (IR),
4. Visible light,
5. Ultraviolet (UV),
6. X-rays and
Ultraviolet (UV) light falls in the EM spectrum radius sandwiched between visible light and X-rays. Its wavelength ranges between 100 nm to 400 nm. Furthermore, it can be grouped into four distinct regions. These are:
1. 100 nm to 200 nm – Vacuum UV or those wavelengths that spread in a vacuum only.
2. 200 nm to 280 nm – used for sanitization and detection.
3. 280 nm to 315 nm – used in medical applications along with curing and tanning.
4. 315 nm to 400 nm – used for printing, lithography, sensing, curing, and medical applications.
How Germicidal UV Lights Work?
Cleansing the air using UV lights is remarkably effective in destroying microorganisms like viruses, bacteria, mold, mold spores, and fungi. As the air blows into the path of germicidal UV light or some surface is exposed to it, the microorganisms present in them are killed. They die because the UV Light destroys their genetic material. This process is also called ionization.
In ionization, the high energy of the UV light causes the electrons to break away from atoms. As a result, a vacancy is created, which affects the chemical composition of the atom, forcing it to break or form bonds that would otherwise not happen. This process is advantageous in chemical processing but damaging to living tissues. For sanitization purposes, the damage to the living tissue is beneficial as it disintegrates the genetic material of the microorganism. In this manner, not only does your home become a safer place, but it also happens to be one of the safest, surest, and most economical ways of decontamination.
Where Are UV Lights Used To Sanitize Air Indoors
Decontamination of the air inside the house is now within everybody’s reach. You don’t need a bulky and overly expensive setup to achieve it. Prominently these are the two ways in which UV lights are used in homes:
1. Air Purifiers With UV Light – Many models of home air purifiers consist of a setup that includes HEPA filters and UV light. The filters trap the contaminants, and the UV light kills them as well as those that are present in the passing air and yet escapes the clutches of the filter. It is an efficient way of leaving nothing to chance. Together these two steps ensure that all harmful impurities are destroyed without posing any risk to the residents.
2. UV Lights Mounted In The HVAC System – Almost all American homes have an HVAC system. So there is no need to buy a separate air purifier. Instead, UV lamps are installed in the unit itself for air purification purposes. There are two types of UV lights used in the HVAC systems. These are:
A. Coil Sterilization UV Lights – Here, a “stick type” or “tube-type” UV light is fitted inside the air handler in such a manner that it faces the evaporator coil. It sterilizes the surface of the coil along with the air that falls in the path of the light. The coil sterilization UV light runs non-stop. It is the most commonly used UV light in the HVAC systems, probably because the price tag attached to it is most economical.
B. Air Sterilization UV Lights – The air sterilization UV lights have a little more complicated setup. It is because an entire UV light unit is mounted in the return air duct. The unit decontaminates the moving air. This type of light does not operate continuously; rather, it cycles on and off with the air handler blower.
Can UV Lights Be Purchased Online?
Genuine UV lights are quite expensive, and they are also sold directly by the manufacturer. So if the online seller is the manufacturer, you can buy them online. However, if that is not the case, it is better to err on the side of caution and skip buying it online. Directly buying the UV light from the manufacturer is beneficial as they take care of its installation. So, you don’t have to hunt for someone to come and install it for you.
Towards The End
UV lights are a game-changer when it comes to improving the indoor air quality. They are being used increasingly in hospitals, care homes, salons, etc. to disinfect the equipment. So the efficacy of these lights is never under question. In today’s environment, when one is unaware of what all illness-causing microbes reside in the air indoors, it is better to take your own precautions. You can now fight back and gain more control over your well-being and that of your family by installing residential air-purifying UV Lights.
