The Science


Active Radiant Catalysis (ARC®)

Our proprietary photocatalytic oxidation (PCO) technology uses energy to activate a catalyst, turning moisture into products that continuously clean your space



Activated Oxygen

Activated oxygen attaches itself to contaminants at the molecular level, destroying them. This process eliminates the contaminant while reverting the activated oxygen back to oxygen.





Creating a plasma of electrical charges, ionization removes allergens and other harmful pathogens from the breathing space, either by pushing them away or causing them to clump together and fall to the floor.
