Let’s start at the beginning …

Q. Why do we need air purifiers?
A. To remove air pollution.


Air pollution can be broken into three segments:

  • dirty air
  • sick air
  • toxic air


Dirty air

Dirty air is made up of large particles, like:

  • particulate matter
  • pollen
  • smoke, and
  • dust.

To clean dirty air, you need to catch these large particles in a HEPA filter or a carbon filter.


Sick air

Sick air contains viruses, bacteria and mould. To clean sick air, you need to kill these contaminants.


Toxic air

Toxic air is the biggest threat. It contains extremely small particles, like VOC’s, that are now believed to be the most damaging to our health. These particles are too small to be caught. To remove them, they must be neutralised or absorbed in a porous material, like activated carbon. However, activated carbon can block very quickly, so what many manufacturers claim to be an effective solution, will be rendered ineffective in a few weeks[1].

So how do Radic8 Viruskillers remove these three types of pollution?


Air purifiers are widely available, and most are effective against pollen, dust and smoke. However, not all air purifiers can sterilise the air: kill sick air and neutralise toxic air.

Radic8’s 2-step air cleaning process makes them superior to other air purifiers on the market.

How it works



Step 1: air filtration


Air purification through mechanical filters is an important first step in air cleaning.  Radic8 units use three filters to capture the large particles in dirty air:

  • a pre-filter
  • a HEPA filter, and
  • a carbon filter.

But this should never be the only step.  Filters are only designed to catch a percentage of the larger particles in the air.  Therefore, as we know, they cannot remove toxic air.  Furthermore, no filter can actually kill viruses[1].

Unfortunately, a lot of air cleaning units stop here.


Step 2: air sterilisation


Air sterilisation is where Radic8 products stand apart from the competition.


After the dirty air has been caught in the filters, it passes through the ‘reactor chamber’.  In here, multiple UV-C lamps are surrounded by chrome nano titanium dioxide tube filters and polished with activated carbon.  This reacts in a process called photocatalytic oxidation.

Photocatalytic oxidation creates the ‘most powerful oxidants known to man – hydroxyl radicals’[1].  No particle can pass past these oxidants alive.  In here, all sick air is killed and toxic air is neutralised.

Hydroxyl radicals only last for a split second, so all the magic is happening right inside the unit.  ‘There are absolutely no by products released from the inside’[1].

What’s more, all this action happens in a single air pass.


Why is it important to sterilise the air in a single air pass?


If only some of the air is sterilised each pass, the units would be spreading dirty air around your room, ‘like standard air purifiers do’ – Daniel Maris, Radic8 Global.

Radic8’s virus killing results of 99.9999% in a single air pass are a result of meticulous design and precision.
