Filtration Technology
The Purivortex AC400 uses a 3-stage filtration system: a pre-filter that captures large particles like pet hair and dust, a True HEPA filter rated to remove 99.97% of airborne pollutants as small as 0.3 microns, and an activated carbon filter that absorbs odors, smoke, and VOCs.
