The patented PHI-Cell® technology in the Guardian Air Desktop utilizes a broad spectrum Ultra Violet (UV) lamp that reacts when directed onto the hydrated sintered catalytic radiant (rare metal coated) surface surrounding the bulb. This reaction releases an oxygen atom, which changes the molecule of water (humidity) from H2O to H2O2, which is in essence vaporized Hydrogen Peroxide also called “hydro-peroxides”. Hydrogen peroxide is a naturally occurring element in the atmosphere that gives us that clean crisp smell after a thunderstorm or in the forest. This advanced oxidation plasma (AOP) is very effective in organically changing the virus, bacterium, mold spore, or odor molecule, attaching itself to them and killing them. Once the reaction takes place with the contaminant, it reverts back to oxygen and water in the air. The PHI-Cell® technology improves the air quality in any indoor environment and is the perfect IAQ solution for any room or office.
