UV-C Lights, Effective Sanitizer

It has become very important that we vigilantly take precautions to prevent ourselves from getting infected from the infectious virus, bacteria, or other airborne diseases. 

The use of the germicidal device has become necessary to use to disinfect items that are not washable with soap and hot water and not compromise our health.  Examples are grocery items that are not washable under hot water, that’s when an Ultra Violet light comes in handy.  A portable UV light can also disinfect rooms and surfaces.  Hospitals use UV lamps to sterilize surgical equipment.  Food and drug companies use UV lamps to sterilize products.  Now homeowners can get this protection as well. Determine the size of the rooms you need to disinfect in your household in order to get the right UV-C light sanitizer.  It helps to have a piece of mind.

How Does UV-UC Light Disinfect?

UV light is a form of light, invisible to the human eye, that exists on the electromagnetic spectrum between X-rays and visible light.  It has wavelengths between 10 and 400 nanometers that make them germicidal.  Thus, capable of inactivating microorganisms such as viruses, bacteria, and germs.  The UV-C technology harnesses a naturally occurring process, hence, the technology makes it an effective, environmentally friendly, and chemical-free method of preventing the infectious virus from spreading everywhere.   According to a report, coronavirus can live on surfaces for up to three days, therefore it is critical to disinfect regularly.  The more common hand sanitizers that have chemical and are widely used at offices and at homes does not necessarily kill the virus as viruses evolved to repair and reverse the temporary damage.  UV-C light is very effective at eliminating 99.9% of viruses and bacteria.

How Does UV-C Destroy Germs?

According to a report, the high energy from short wavelength UV-C Light is absorbed in the cellular RNA (Ribonucleic acid, virus general material) and DNA, damaging nucleic acids and preventing microorganisms from infecting and reproducing.  The absorption of UV-C energy forms new bonds between nucleotides, creating double bonds of dimers. (Dimer is a molecular complex consisting of two identical molecules linked together)  Examples of large DNA viruses that infect humans are adenovirus, herpesvirus, and poxvirus.

Using the UV light as your sanitizing method will prevent the microbiomes from replicating, thus, they do not infect.  The damage is done at a cellular level of the virus, the UV light provides an effective strategy to completely kill.

How to Use UV-C Light Safely?

When using the UV light to sterilize goods, make sure you are aiming the UV light directly at the items.  Never aim at any part of your skin and also keep away from your eyes. UV rays can cause painful eye irritation.  Exposure to UV rays can cause sunburn, premature aging of the skin, and signs of sun damage such as wrinkles, leathery skin, liver spots, actinic keratosis, and solar elastosis.  UV rays can cause eye problems.  Ozone gas that is emitted during disinfection can cause respiratory irritations, difficulty breathing can cause coughs.   Use it away from animals as well and also plants.   Ultraviolet lamps are very effective in killing germs but can pose an imminent danger if used without taking the proper precautions.

What UV-C Light Do You Need?

  1. Looks like the UV lights provide a very effective way of cleansing our surroundings of the deadly viruses. I particularly like the fact that you can use it to cleanse grocery items when coming from the grocer. You have no way of knowing what environment the groceries passed through and who handled them before you. The only way to feel safe is this UV light. Thank you for sharing this. We should all get our hands on these devices. Better safe than sorry
