Contaminated air that comes into contact with the Reactor Chamber is in for a rough ride. In the first stage of the VIRUSKILLER™ process, air is confronted with a series of ultra-high-end filters consisting of a pre-filter, carbon filter, and a generous HEPA filter. This triple-filter arrangement effectively traps particulates, irritants, and other ultrafine particles that can cause respiratory issues, while the carbon filter neutralizes toxic gases and volatile organic compounds (VOCs).
However, this is only half the story — filtration alone is not enough where bioaerosols are concerned. Eliminating airborne pathogens and microorganisms requires specialized technology, and it is from here that the air moves into our patented Reactor Chamber.
The Reactor Chamber is the heart of VIRUSKILLER™ and is the core technology that has been continuously developed and matured to power our world-class air decontamination performance since 2004. Featuring a number of key design elements that allow it to efficiently deactivate germs, bioaerosols, and other airborne pathogens, the Reactor Chamber turns an already high-end air filter into a total solution for indoor air safety.
While the VK range does employ UV-C emitters, UV irradiance is not the only decontamination technology in use. The emitted UV light itself offers an overall, low-level decontamination effect and serves to trigger the more important of the two decontamination processes — photocatalytic oxidation (PCO).
There are two main components to the PCO process: UV light and a surface coated in titanium dioxide (TiO2). The UV light reacts with the TiO2 catalyst to produce hydroxyl radicals, which attack the organic compounds in bioaerosols and break them down into trace, harmless amounts of water and carbon dioxide:
The Radic8 Reactor Chamber features a unique layout of TiO2 filters designed to maximize the active surface area in which the UV light comes into contact and are laid out to ensure air passing through receives as much exposure as possible to the germicidal effect of the photochemical reaction.
In addition, we know that just one or two UV-C lights are not powerful enough to destroy airborne microorganisms efficiently — especially at power levels considered safe for consumer use. As such, Radic8 employs a bank of no fewer than eight premium UV-C lamps, ensuring optimal coverage of the entire airflow path within the Reactor Chamber.
The combination of hexagonal TiO2 filters and high-power UV-C lamps means we have one-of-a-kind photocatalytic exposure to contaminated air within the chamber. The large amounts of UV light produced reflect on the surfaces of the tube filters, ensuring complete distribution of the germicidal action of hydroxyl radicals – and maximum decontamination performance.
