The NQ Clarifier Medical Plus air purifier offers an advanced purification system to treat many types of air pollutants. It uses four levels of filtration, including a True HEPA filter, Activated Carbon filter, pre-filter, and post-filter, as well as a comprehensive purification zone that destroys bacteria, viruses, fungi, and molds. Contaminated air is continuously re-circulated with a large 350 cfm fan and through four inlet grills, and up to 99.97% of particles 0.3 microns or larger are removed. In addition, the NQ Clarifier Medical Plus air purifier features specially-sealed internal components which prevent internal leakage, and the patented interior reflective chamber amplifies the intensity of the four UV lamps by up to 66 percent.
