1. Intro

What is the difference between Radic8 and Viruskiller™?

Radic8 is the company that owns and manufactures the highest certified clean air technology in the world, called Viruskiller™.

How is Radic8 different from other air purifiers out there?

History: Viruskiller™ core technology was initially funded by the Korean Government after the 2003 SARS epidemic. For the past 16 years, the technology has been focused on killing airborne viruses and has since been installed in over 80% of hospitals in South Korea, all lung examination rooms, universities, and more.

Airflow: One of the most overlooked aspects in air sterilization is controlled airflow. Viruskiller™ units have been designed in collaboration with South Korea’s Aerospace University to achieve unparalleled airflow control in indoor settings ranging from operating theaters, to waiting rooms, to offices.

Single Air Exchange Kill Rates: If a technology draws contaminated air in, then pushes it back into the breathing zone without completely sterilizing it, it dramatically increases the risk of cross contamination. When it comes to viruses, the only relevant test results are on a single air exchange, where our tech achieves 99.9999% virus kill rates.

How does your technology kill viruses?

Studies show that viruses can penetrate HEPA filters, so after our HEPA we use our patented reactor chamber which is full of UV radiation and nano oxidisation that breaks the RNA of viruses. Our test results show a 99.9999% kill rate on respiratory viruses, including Coronavirus, on a single air exchange.

2. General

Do the units come with all the necessary parts (like ducting) to create negative or positive pressure?

The optional collar attachment for positive or negative air pressure and the ducting needs to be bought separately. We only provide the air sterilization unit. VK Medi and VK 103 for creating positive pressure systems and VK 102 for creative negative pressure systems.

What is the length of the power cable?
The length of the power cable is 1.2 metres.
What happens when the viruses and dust particles fall onto the floor instead of going through the units? Do viruses remain active?

Yes our units remove viruses from the air and reduce surface settlement by up to 80% if installed correctly, they cannot however do anything about viruses and other contaminants that have already settled onto the floor.

3. Certifications

Has the Viruskiller™ technology been independently tested?

The Viruskiller™ technology was funded by the Korean Government as an emergency response to the 2003 SARS epidemic and was developed by a consortium of universities and government bodies. The first virus killing tests arrived in 2004, showing a 99.9999% kill rate on Corona Virus, Adeno Virus, Influenza Virus and Polio Virus.

Since then, the technology and individual units have been tested numerous times on different strains of bacteria, ozone generation, ultra fine particles, VOC’s and more. There is probably no other technology on the market as extensively tested as Viruskiller™.

Where are Viruskiller™ units installed?
The Viruskiller™ technology was developed in South Korea where it also has its largest installation base. There are over 370.000 commercial installations in South Korea alone, which cover more than 80% of hospitals and universities, all lung examination rooms, schools, government buildings, restaurants, elder care homes, etc.
Do you have KFDA certification (Korea)?

Radic8 products are used in many sectors as well as the medical sector. We have therefore not registered it with KFDA as a medical device.

4. COVID-19

Does Viruskiller™ kill COVID-19 from surfaces?

Our tests were conducted on SARS coronavirus which has almost an identical size/structure/envelope as the current Covid19 and is widely accepted as a substitute.

The forced airflow will greatly reduce surface settlement of viruses and therefore reduce the viral load on the surfaces. Radic8 technology does not actively kill viruses on surfaces but it does reduce the amount that can settle on the surfaces by destroying them while they are still in the air.

If a patient has Covid-19 but is asymptomatic, or has the flu for that matter, how effective is the unit in purifying the air and preventing viral transmission?
The Viruskiller™ units aim to create a controlled airflow in any indoor setting. The powerful fan will draw contaminated air away from the breathing zone, sterilize it and then send it back into the breathing zone. This will greatly reduce the risk of cross contamination through airborne and droplet particles. Please see the attached PDF for more info on controlled airflow.

As the Corona Virus is present in droplets and not airborne, how is the Virus Killer unit able to target these droplets to kill these viruses?

Whilst Covid19 is thought to be predominantly transmitted by droplets, they can be various sized droplets, including fine droplets that can stay in the air for hours. Droplets not only released whilst coughing or sneezing. The simple act of talking, eating and even breathing can release them. (please see the attached video from Japan). This is why many governments, including our own, have now made mask wearing compulsory for the general public. There are many studies that have been done on this matter (such as this one: https://www.nejm.org/doi/10.1056/NEJMc2004973).
In addition, it is a known fact that virus droplets attach to larger particles in the air such as dust, pollution or other particles and then effectively becomes airborne. This is why maintaining clean air reduces the risk of viruses being transported through the air. There is increasing evidence that the Corona virus is airborne due to pollution and other particulate matter.

5. Installation and maintenance

What is the warranty on the products?

We offer a standard 1 year manufacturer’s warranty.

Breakdown within 7 days: Replacement
When functional or mechanical defects are occurred within 1 month from the date of purchase: Free of charge
When same defects occurred more than 3 times during warranty: Free of charge
Reactor cell is under warranty guarantee for 12 months from date of purchase

Can it be used in conjunction with an air conditioning unit? How does it work in terms of airflow and efficiency? What if the A/C is centralized?
Radic8 technology is often used in conjunction with A/C units and the airflow from the A/C should be taken into account before best positioning of the Radic8 devices are decided upon. A/C airflow should aid the airflow being directed into the Radic8 device as opposed to countering it. PDF: https://radic8.com/wp-content/uploads/2020/05/Airflow-control.pdf
Do the windows in the surgery need to be closed for maximum airflow efficiency? How will air conditioning position influence efficiency of the unit?
Windows will allow fresh air input and this is important but it is not advisable to have the Radic8 units too close to an open window. Airflow from an air conditioning unit will influence the forced airflow of the Radic8 unit and should enhance the flow of air going into the unit as apposed to countering it.
