Halo is continuously pulling the dirty air in the lab through the filter, adsorbing the molecules that cause noxious odors, and returning clean air back to the room through low-disruptive side vents. The laboratory-grade molecular filtration system contains Neutrodine, a unique and powerful activated carbon mixture combined with a pre-filter that captures a large variety of airborne fumes and odors, which left untreated, could represent a potential health hazard.
