UV light is highly effective at killing germs

There are three types of Ultra Violet rays: UVA, UVB, and UVC. UV-C rays have the shortest wavelength, and therefore are the strongest at fighting germs. These types of rays are effective at killing viruses and bacteria, also known as pathogens. UV-C light has a wavelength between 200 and 400 nanometers (nm). The reason ultraviolet light is so effective against pathogens is that it destroys the molecular bond which holds together the DNA of these superbugs.

Does UVC Light Kill Coronavirus?

According to Consumer Reports, "Most likely," as UV light has been proven to kill similar viruses and bacteria. A recent study in 2017 demonstrated that the ultraviolet "c" light killed MRSA bacteria as effectively as the more powerful rays. The same study was repeated in 2018 on H1N1 virus, yet again it was found to be effective at killing germs without toxic chemicals.

UV Light Sanitizer Dangers

Humans and animals should not be in contact with ultraviolet light since it can cause burns and has been linked to diseases such as skin cancer and cataracts. There are a few options available if you want to use a UV light to kill bacteria:

  • If using a handheld UV light sanitizer do not point it at yourself or others
  • Wear gloves to protect your hands
  • A safe alternative is to use a remote-controlled UV Light and leave the room while the light is on.

Usage Tips for UV Sterilization Lights

  • Do not use for sterilization of humans, pets, animals, plants or food.
  • Do not use directly on skin or eyes.
  • Keep away from children. These devices are NOT toys.
  • Do not touch the light surface when in operation.
  • Keep the surface of light clean to ensure effective operation.

The Best UV-C Light

Not all UV lights and bulbs made equally. There are dozens if not hundreds of poorly made Chinese lights on Amazon, eBay, and other markets. These lights are relatively inexpensive compared to UV lights proven to kill germs.

The best UV light will depend on how you intend to use it. Whether you want to disinfect small objects such as your mobile phone, groceries, door handles and other frequently touched objects; or you want to disinfect your entire bedroom.

Small and Portable

For small objects, we recommend you use a handheld light. These are portal ultraviolet light sanitizers that do not take up a lot of space and can be easily carried around with you. Some models are battery-powered, so you can use them on the go or in your car.

  • Simple one-button operation.
  • Uses a built-in battery that needs to be charged.

Powerful - Capable of Disinfecting a Room

If you want to kill germs in an entire room, it will be necessary to get a stationary light that needs to be plugged in. These UV light sanitizers often have a remote or a delayed-time start. This is a very convenient feature so you can leave the room while the disinfection is in process. 

UV Light with Air Purifier

Another alternative to a handheld or stand-alone UV light is an air purifier that kills germs by sucking in the surrounding air, trapping the pathogens in a HEPA filter and zapping these pathogens with ultraviolet light.

At the time of this writing, all three options were readily available on Amazon. Many publications have published stories about the use of UV-C light to sanitize as an alternative to alcohol and Clorox/Lysol. Amazon is limiting its supply to essentials and these products may be sold out shortly.
