Why do you need UV germicidal lights? They’re some of the most effective ways of removing bacteria, airborne pollutants, and flu viruses (such as coronavirus – COVID-19) from the air inside your home. The ultraviolet light helps disinfect indoor air making it safe. In this post, we’ll talk about what you should know about germicidal UV light.

What is a Germicidal UV lamp?
The UV-C lamp forms equivalent bonds between specific adjoining DNA bases. As a result, it ends up destroying the nucleic acid of pathogens. When these bonds form they stop the DNA from being opened for reproduction. The organism at this point will have no means of reproducing. Sometimes it may try to reproduce but when that happens it ends up dying.
How Does Germicidal UV Light Work?
The UVC bulb produces electromagnetic radiation whose wavelengths are greater than X-rays but lower than visible light. It’s also part of the light range that lands in between visible light on the higher end and X-rays on the lower end.
Ultraviolet light is part of the light spectrum landing between X-rays on the low end and visible light on the high end. The UV spectrum ranges from 100 nanometers (nm) to 400 nm. UV range falls between 100 and 400 nanometers. UV can be divided into different ranges with UV germicidal light said to be short wavelength.
Nucleic acids highly consume wavelengths that fall between 200 nm and 300 nm. Any consumed energy can cause deficiency which includes the pyrimidine dimers. These usually stop reproduction and bar generation of essential proteins. It’s this kind of restriction that kills harmful organisms. Let’s find out how different types of germicidal uv light operate. Can this type of UV light be harmful to you?
Mercury based bulbs running at a low steam pressure produce UV light on the 253.7 nm line
Pulsed-xenon lamps produce UV light through the whole UV range with maximum emissions close to 230 nm. Ultraviolet light-generating diodes or UV-C bulbs produce UV light at selective wavelengths ranging between 255 and 280 nm.
This process can be compared to the effect of long wavelengths stimulating sunburns in humans. UV is strong which means microorganisms never survive when exposed to it for a long time.
Is UV Germicidal Light Safe?
This is one of the biggest questions that many people struggle with. Let’s see how you’ll benefit from using UV germicidal light.
1. Reduced germs in your house
The germicidal UV light produces a high light intensity. They come with strong ultraviolet energy which reduces the accumulation of airborne pathogens by up to 50% in 45 minutes only. As a result, it acts as an air purifier inside your house which minimizes allergy symptoms and helps you recover from illness faster. Clean air stops the spread of airborne bacteria and viruses across your house.
2. Boosts the performance of HVAC
Killing germs in your ductwork helps remove harmful components from the air ensuring that you don’t inhale them. It also maintains cleanliness in the coils and ducts as well as cooling and heating components in your home. This is a great way of ensuring that the HVAC system operates efficiently.
3. It’s flexible which makes it easy to install
A UV bulb is located inside the ductwork. This makes it compatible with almost all heating and cooling systems. The UV germicidal light installation process is fast and easy and you can do it without the help of a professional.
4. There don’t discharge ozone emissions
Some air purifiers discharge ozone as a by-product. It’s important to mention that ozone irritates the lungs. It can also worsen asthma and allergy symptoms in people with a delicate respiratory system – check out the best air purifiers for asthma.
UV germicidal lamps neither produce ozone or chemicals during the disinfection process. You can be sure they won’t leave any byproducts in the air. What they do is destroy any germs without causing additional harm to you or your loved ones.
5. Low priced requirements
Germicidal UV light operates consistently whether your air conditioner or furnace is running or not. Even then the cost of running your UV bulb will be manageable. To reduce the operating costs further you’ll need to maintain and repair your germicidal lamp regularly.
6. You can use it to disinfect water
You can use a water treatment UV gadget to disinfect a surface and water drawn from wells. The cost and labor charges of a UV germicidal light water treatment systems are similar to traditional disinfection gadgets.
Water chlorination is one of the commonly used water treatment methods. It removes big organisms and disinfects the water. However, you’ll find that these systems can be quite expensive. Companies will have to cover the cost of training operators too.
One big problem with these systems is that employees can be exposed to hazardous materials. Boiling water is another method that has been used for years. However, it requires labor and may not be cost-effective. UV germicidal treatment, on the other hand, is fast and more efficient when it comes to use of energy.
