UV-C Light: A new technology used to fight the spread of bacteria & germs

We are now living in a world where disinfecting ourselves and our belongings has taken the utmost priority.

Under the current threat of COVID-19 or the novel coronavirus, the importance of sanitizing our most frequently used gadgets and appliances is unprecedented.

It is more than a matter of basic hygiene and has become an issue that could seriously impact our health and that of our loved ones.

Given the current scenario, we are looking for the quickest, easiest and safest ways to protect ourselves from germs like bacteria and any kind of virus.

UV-C light is a type of ultraviolet light that has been proven to kill microbes by destroying their DNA.

Our products from Sannify provide you with a safe and convenient method of decontaminating your cellphone, keys, earphones, or any number of other small household items that you come into contact with most often.

 Due to its proven effectiveness in destroying several types of viruses including H1N1 and types of coronavirus like SARS, extensive research is currently underway to determine if UV-C is effective against COVID-19 or the novel coronavirus.  

How has ultraviolet light been used for decontamination?

Over a hundred years ago, scientists discovered that ultraviolet light with short wavelength (also called UV-C light) has germicidal capabilities. When trained on microbes, the light destroys the DNA of the microbes, rendering them impotent or dead. One of its earliest applications was in 1903 in the field of medicine, when it was used to cure skin infections like lupus vulgaris and tuberculosis.  

Its most widespread use followed shortly after that in water treatment plants and purification systems. When combined with the filtration system, it adds an extra layer of decontamination by keeping the water free of contaminants such as bacteria and a variety of germs. Parasites that have developed a resistance to most chemical disinfectants are destroyed by UV-C.

Its uses are not limited to wastewater treatment alone, however, and several countries have now permitted its use in the purification of drinking water as well.

A new technology has been developed where it is combined with ozone and hydrogen peroxide to remove more varieties of contaminants.

UV-C light is used in air purification systems. The air needs to be forced past the lamps for maximum contact. For this reason, ultraviolet air purifiers are usually not effective if they are standalone units. They are integrated into a larger purification unit along with a HEPA filter and forced-air system. The air in the room is forced through the system and past the lamps for effective decontamination. The powerful filtration system then removes the dead pollutants.

A few other domains where UV-C is used are aquariums, the food industry and laboratories.

In aquariums, a small ultraviolet lamp integrated with the filtration system keeps the water free of harmful microorganisms by preventing their reproduction and propagation.

In labs and medical facilities, they are used to sterilize equipment, implements and protective gear.

In the food industry, they are used to pasteurize fresh juices to remove harmful pathogens and extend their shelf life.

UV germicidal irradiation (UVGI) is the general term for the use of short-wavelength ultraviolet light as a decontaminant of air, water, food, and other surfaces.

How does ultraviolet light destroy microorganisms?

In the light spectrum, ultraviolet light lies in between visible light and X-rays in terms of wavelength. Short-wavelength ultraviolet light, which lies between 200 nm and 300 nm, is a powerful germicide. It is called UV-C and this property differentiates it from UV-A and UV-B types of ultraviolet light.

UV-C is absorbed by nucleic acids. Pathogens like bacteria, virus and other germs are single-celled organisms. Once their DNA is destroyed by the absorbed UV-C, they are rendered inactive and cannot reproduce and spread.

The basic concept is that UV is emitted by bulbs and the medium that needs to be disinfected is circulated over them repeatedly for maximum exposure and effectiveness. The effectiveness depends on the intensity and time of exposure.

The optimum dose of UV-C provided for the minimum required amount of time will be most effective in killing the largest number of pathogens.

A few factors that need to be mitigated are turbidity of the bulbs, reduced intensity of the bulbs due to ageing, and the cooling of bulbs due to repeated air or water flow.

How safe is it to use UV-C in human environments?

Ultraviolet light spans a spectrum of 100 to 380 nm in terms of wavelength.

UV radiation, in general, is harmful to humans. Its level of damage depends on which type of radiation you are exposed to.

  • UV-A is the longest wavelength ultraviolet light and comprises more than 90% of the ultraviolet light that passes through the atmosphere to reach earth. It is responsible for the ageing of skin like wrinkles and age spots and penetrates deep into the skin layer.
  • UV-B is mostly filtered out by the ozone layer and not much of it reaches the earth’s surface. Prolonged exposure to it can cause tanning and eventually lead to skin cancer, even though it cannot penetrate the skin layer.
  • UV-C is the shortest wavelength ultraviolet light. It is the most harmful to humans and is completely filtered out by the earth’s atmosphere. Its damaging effects on living organisms is harnessed only for decontamination.

It is artificially generated, and with properly regulated use and the best safety measures in place, its disinfectant benefits far outweigh the potential hazards.

UVGI systems are not exposed to humans. They are used in sealed environments and the UV-C rays are turned off when the system is opened for inspection or maintenance by humans. UV lamps are “doped” to minimize ozone production, which is a harmful by-product of UV light.

UV-C can corrode plastics and rubber which are abundantly used in any filtration or purification system. These parts are protected from direct exposure to UV light.

A research team at Columbia University is conducting experiments with far-UVC rays that have a wavelength of 222 nm. They destroy viruses but are purportedly safe for humans.  

How does Sannify work as a disinfectant for household items? 

Under the constant threat of COVID-19 or the novel coronavirus, we are strongly advised to wash our hands vigorously so that the friction can break the protective protein coating of the virus and destroy it. Or we use isopropyl alcohol or ethyl alcohol to wipe and disinfect household gadgets and surfaces that could be exposed to the contagion because alcohol in the proper concentration can destroy the protein coating of the virus almost instantly. UV-C has the same destructive effect on the coating.

Our phones, car keys, watches, earphones, and many other household items are exposed most to germs on hands and surfaces through frequent handling and being moved around and placed in several places.

There may not always be time to disinfect them with a wipe after every potential contamination, not to mention how cumbersome it is to do so.

UV-C light sanitizers allow you to clean your items quickly and easily in a contact-free manner. They do not use liquids, chemicals, or heat, all of which could damage your possessions.

Sannify products, or SanniBoxes, are sleek and conveniently-sized UV-C sanitizers that clean your most vulnerable household items. You do not directly come into contact with the light, and the case is well-insulated, so there is no danger to your health when you use it. A high-intensity UV-C light is emitted in the controlled environment of the SanniBox, and your gadgets are disinfected.

Our internal laboratory tests, as well as research conducted by independent organizations like The National Institute of Standards and Technology, International Centre for Illumination, and Illumination Engineering Society, have concluded that 99.9% of the following bacteria, germs, and viruses are destroyed by UV-C.

  • E. Coli
  • Salmonella
  • Staph Aureus
  • H1N1
  • Phage
  • Common cold

While SanniBox has not been tested specifically for the novel coronavirus, it has been proven to be effective against other similar viruses like H1N1 through conclusive laboratory tests.
