Single Air Pass: Preventing Cross Contamination

Room air exchanges, fan speed, coverage – these are all compelling figures when it comes to determining the performance of a device designed to move air in a given space. In addition, air sterilisers – devices designed specifically to eliminate airborne viruses, bacteria, mould and fungi – need an impressive bioaerosol kill rate in order to be truly effective.

But even the most compelling performance figures only tell a small part of the story. Given great sterilisation performance and optimal airflow in a space, one question remains…

How many times does a given quantity of air need to pass through a device in order to be truly sterilised?

SINGLE AIR PASS

The best case is easy to understand: Viruskiller boasts near-100% virus elimination in only a single air pass through our Reactor Chamber, the patented sterilisation technology at the heart of every VK unit.

In short, contaminated air that moves into our units is immediately sterilised, sending clean, fresh air back into the breathing zone of the room:

MULTIPLE AIR PASSES

Now, consider what happens when a device requires multiple air passes in order to achieve virus-free air:

Devices that require multiple cycles in order to achieve sterilisation have the unfortunate result of sending either partially contaminated air, or air that has simply never been sterilised at all, back into the room – where it can go on to infect or harm occupants.

Even worse – that same, partially contaminated airborne pathogen needs to make its way back into the device, multiple times, in order to be truly sterilised, of which there are no guarantees. This has the ultimate effect of “mixing” contaminated air around the room, which is unacceptable if occupants are expected to be in the space while the unit is active.

THE ENGINE BEHIND REAL-TIME PROTECTION

Viruskiller’s ability to eliminate particulate matter via filtration, viruses and pathogens via sterilisation, and to do so in a single air pass means the prevention of cross-contamination in real-time – reducing the risk of bioaerosol infection from infected individuals. At all times, the air leaving our units is clean, fresh and safe for occupants to breathe – offering true peace of mind to those in our shared spaces.
