Recent studies have shown that the UVC light is able to disarm the genetic material in the virus that causes COVID-19.

As schools and colleges across the world gear up to reopen, ultraviolet (UV) lights are emerging as the best way to disinfect classrooms, pathways and seats from COVID-19.

Several studies support the effectiveness of UV lights in sanitizing some living and working spaces, frequent use items and even food products.

Can ultraviolet light prevent COVID-19 spreading by reducing contamination?

Yes, ultraviolet light can be used to annihilate or destroy the novel coronavirus and it is safe to use a UV light for disinfection purposes at home, educational institutions, work places and public areas.

Ultraviolet light is generated by the sun and by special purpose lamps and are divided into three major types – UVA, UVB, and UVC – based on their wavelengths.

Research indicates that the UVC light that has the wavelengths of light from 200 to 280 nanometers is able toincapacitateand destroy the genetic material in previously seen coronaviruses. A more recent researchreport shows that it can also obliterate SARS-CoV-2 virus or COVID-19.

This UVC light is much “potent” than regular sunlight and has a wavelength that varies from 200 to 280 nanometers.

Exposure to a wavelength of around 252-254 nanometers for approximately ten minutes neutralizes or exterminates bacteria and viruses by harming their cell walls in case of SARS-CoV-1. It can also be effective in the case of SARS-CoV-2. However, these wavelengths are verydangerous to humans.

Experiments have also shown that UVC light (207–222nm) effectively deactivates human coronaviruses including SARS-CoV-2, which have not resulted with any harmful effects on human skin.

It is also crucial to know how to use UVC light for sterilization. The wavelength, dose and duration of exposure need to standardised and deployed carefully.

The World Health Organisation (WHO) has also advised that UVC lamps should not be utilizeddirectly on human skin.

The World Health Organisation (WHO) also advises the use of chemical disinfectants for sanitising surfaces and products. However, chemical disinfectants have lingering effects and cannot be used to disinfect many items like eatables, phones, laptops, watches etc.

Ultraviolet light does not have a residual effect and can effectivelyclean these products.

How does ozone work as a disinfectant?

Ozone disinfection technology is another alternative for effectively cleaning fruits and vegetables. Products that need to be disinfected are placed in a specially designed Ozone disinfection box for a specified period of time. Ozone, a type of oxygen molecule, is proven to incapacitate many pathogens, and experiments in the past have shown that high concentrations, between 1-6 ppm, were successful against the coronavirus but theoretically toxic to humans.

At Planet Disinfect you we have simplified your search for such gadgets thatare built with UVC or Ozone technology. You can choose from a select range of Food Ozone Sterilizers, Germicidal UV Lamps, Wands, Boxes& Cabinets, etc.
