This winter, choose the right protection

Updated: Mar 31, 2022

There is a lot of conflicting data out there right now; do you buy a UV-C sanitiser or do you buy a HEPA air purifier/filter unit to keep you safe from viruses, bacteria and other nasties this cold and flu season.

What is the difference between the protection level of an AIR UV-C sanitiser versus an air purifier?

Normally a quick conversation highlighting the science clears up any confusion.

"AIR uses UVC to scientifically destroy the DNA & RNA of virions. Covid-19 virions are the sized 0.06 to 0.14 microns, and can pass right through a HEPA filter"

Unlike a device that relies on costly HEPA filters, the AIR UV-C sanitiser destroys the DNA and RNA of pathogenic microorganisms - viruses, bacteria, moulds and fungi, rendering them 'disrupted' and unable to reproduce. The air that exits the unit is not only clean air, but continually cleaning air, as the disrupted DNA and RNA latches on and kills pathogenic microorganisms to create a sanitised environment.

An air purifier relies upon HEPA filters. If a HEPA filter can filter particles to 0.3 microns, and Covid-19 virions have been measured to be 0.06 to 0.14 microns, they will pass right through a HEPA filter and continue to circulate in the air around you, settling on exposed surfaces.

Just plug it in for up to 5 years of continuous use with no costly add ons or extras.

If you want more of the science, the sources used can be found below by clicking on the links:


According to The Lancet, medical journal, Electron microscopy of SARS-CoV-2: a challenging task Covid-19 virions have been measured in two different studies with the following results:

0.06 microns to 0.14 microns

0.07 microns to 0.11 microns


HEPA-16 filters effective from

1.0 micron to 0.3 microns

The science is very clear here, and there is lots of documentation to support it....In fact the United States Environmental Protection Agency have a whole bunch of information on what HEPA-16 filters are capable, or rather incapable of.


What is a MERV rating?

MERV is an industry standard "Minimum Efficiency Reporting Value" and is used to rate the effectiveness of air filters.
