| Traps surrounding polluted air, smoke, smog, smells, aero-allergens, pollen, bacteria, spores and dirt into the chamber through the inlet tunnel at the rear aperture on the top unit. |  | Once ORCA has cleansed the polluted air, the purified air is atomized and released back into the surrounding air, releasing molecules of ORCA solution, water vapour and negative ions. This unique process enables ORCA to effectively reduce aero-allergens, bacteria and other pollutants and vastly improve your indoor air quality. |
