The quality of air is a key that directly imapcts our physical and mental wellbeing. It has become even more crucial with airborne transmission especially during the Covid-19 pandemic. Reducing risks of airborne transmission requires more than opening doors and windows or installing standard air filters which may not be effective against enveloped viruses.

Our innovative technologies in VIRUSKILLER™ Air Purifiers are effective in detecing, filtering and purifying polluted air. The VIRUSKILLER™ series had been tested and certified by world-trusted laboratories with the performance in eliminating 99.9999%* of viruses, PM 2.5, bacterias as well as filtering harmful pathogens in the air. Installing these units will help decreasing the risks of airborne transmission and making your indoor spaces safer for visitors and staff.

In the first 3 steps in air purifying process include pre-filter, carbon filter and HEPA filter which you can find in leading air purifiers in the market. These filters help filtering out large particles of more than 0.3 micron. However, most do not have the capability to eliminate viruses in the air.

The outstanding feature of VIRUSKILLER™ is a Reactor Chamber inside where Titanium Dioxide (TiO2) filters react to oncoming Ultraviolet (UVC) light in a process called Photocatalytic Oxidation. This process enables the VIRUSKILLER™ to capture and eliminate 99.9999%* of viruses in the air and also neutralised toxic gas, odour and VOCs.

VIRUSKILLER™: Beyond Air Purification

VIRUSKILLER™ is more than just an air purifier which can kill 99.9999% of coronavirus, bacteria, fungi, mould, VOCs and other harmful airbourne substance with just a single air pass.

Today, there are a lot of air purifiers in the market for you to choose from. Most of them uses HEPA filters to filter out tiny particles such as PM 2.5 in the air with up to 99.95% or even 99.99% efficiency, but they still lack the ability to kill viruses. Moreover, these air purifiers cannot deliver sterilised air within a single air pass. Instead, the machine will have to work continuously (multiple air passes) to gradually better the air quality. This is not ideal for places where people often enter and exit as it will continue to contaminate the air.

VIRUSKILLER™ is designed to be a one-stop solution to your air hygiene problems. With 99.9999% single air pass kill rate, they not only filter out particles, but also help kill airbourne bacteria and viruses as small as 0.1 μm. This enables you and people around to experience real-time airbourne virus protection for an enhanced quality of life.

VIRUSKILLERTM also boasts of a log 6 virus elimination efficacy with 99.9999% effectiveness. Though the 99.9999% efficacy, when compared with 99.95% or 99.99% efficacy of leading air purifiers, might seem like only a few decimal points apart. However, if we take a deeper look, we can see that the log 6 efficacy is hundreds of times more effective.
