The NQ Commercial Clarifier is a portable, self-contained room air purifier. Features include a five-stage filtration system that uses UV light to kill biologically active, airborne contaminants; a HEPA filter; a carbon-blended filter to adsorb gases and odors; and a fan speed control knob. Indicator lights show when it is time for maintenance of the UV lamps or filters, the company says. The unit is designed to move about 350 CFM of air through its system at the high-speed setting. According to the manufacturer, the germicidal irradiation is based on the same disease-killing technology used in hospital operating rooms and quarantine suites throughout the world.
