Filters And Performance

Let's talk about the highlight of 1000 G3. Unlike most UV air cleaner that comes with a single filtration, Air Oasis 1000 G3 is powered by the patent-pending advanced hydrated photocatalytic oxidation with germicidal UVC. A revolutionary technology from the great Einstein and NASA that help clean the air in space shutter. The inflow water vapor will be sterilized through AHPCO catalyst and the broad-spectrum ultraviolet light will kill 99% of Mycotoxins mold, bacteria, viruses, H1N1, mold, and MRSA. It can also remove toxic chemicals like VOCs, Legionella pneumophila, Aeroallergens, and Formaldehyde to trace levels. The 20,000,000/cm³ Bi-polar ionization will diffuse ions into the air and break down airborne particles on a molecular level. Finally, the leftover oxidizers will slowly be converted, released back into safe oxygen and hydrogen.

GermGuardian GG1100W/ GG1100B

A simple, easy to use, wall pluggable UV sanitizer. Less than 50 but comes with a small coverage that is only meant for close-range purifying.

Airocide APS-300

Arguably the more eye-catching air purifier that also uses NASA developed PCO technology to kill bacteria and viruses. Way more expensive to own and maintain.
