How UV water treatment can help you stay safe from COVID-19

Apr 27 2021

Early on in the COVID-19 pandemic, UV light was shown to deactivate the coronavirus by removing its ability to mutate, rendering it inactive.

This research showed promise for air and surface disinfection. It wasn’t long before UV light was tested in water treatment and similar positive results were found, where it enabled the rapid, effective inactivation of the COVID-19 virus.

UV light does not “sterilise” water. It “disinfects” it. It does this not by removing the coronavirus, but by removing its ability to reproduce. This renders the virus “inactive”. Inactive viruses have lost their disease-producing capacity, so they cannot make you ill.

The main type of UV used is UVC. UVC is by far the most effective wavelength for killing the coronavirus. Since it was first discovered in the 1870s, UVC light has been used for disinfection in hospitals. This radiation destroys the genetic material of viruses and bacteria, rendering them inactive and non-dangerous.
