The Radic 8 Virus Killer South Korea has some of the strictest indoor air regulations in the world. VIRUSKILLER™ was created by INBair as part of governmental response to the 2003 SARS epidemic. Over the last 16 years, VIRUSKILLER™ has been installed in over 370 000 sensitive and public spaces throughout South Korea. Indoor spaces are contaminated by invisible pollutants which include dirty air, Toxic air, and sick air. The Virus Killer filters the particulates, dust, pollen, and dander from the dirty air. The toxic air is also neutralized of all the gases, smoke, and fumes by the Virus killer making it breathable and finally, Radic 8 decontaminates Viruses, bacteria, mold, and fungi that are harmful. Virus Killer Technology Airflow control – Our units are designed to draw exhaled air down to the floor, and then towards the intake of the unit. The contaminated air is then filtered and sterilized, before being sent back into the breathing area of the room. This creates a persistent, laminar airflow that is constantly pulling contaminated air away from the breathing area, and replacing it with clean, fresh air. VIRUSKILLER™ units spare no Expense on filtration. A full suite of three filter stages are built into our VK units as standard Pre-filter: Catches larger particulates and irritants. Carbon filter: Neutralizes most gases and VOCs. HEPA filter: Traps air particles as small as 0.3 microns.
