Bi-polar ionization vs. photocatalytic oxidation (PCO)

Air Oasis employs two types of ionization: an advanced form of photocatalytic oxidation (PCO) and bi-polar ionization (cold plasma). One or more of these technologies are in each of our air purifiers. Both address common concerns related to viruses, bacteria, and mold in the air and on surfaces. We improved upon the standard PCO ionization with our proprietary AHPCO® (advanced hydrated photocatalytic oxidation) technology. AHCPO® ionization is recommended for tackling unwanted odors, whereas bi-polar ionization is helpful to those concerned with airborne particulate matter such as allergens, dust, or mold spores. While both AHPCO® and bi-polar ionization are effective against all of the contaminants mentioned previously, these are the ones we recommend each technology for. For help deciding which air purifier is right for you, take a look at our Air Purifier Selection Tool.

What is photocatalytic oxidation?

Photocatalytic oxidation is the process whereby ultraviolet light photons react with a photocatalyst. The unique Air Oasis AHPCO® catalyst consists of a proprietary combination of very specific elements. As photons from the UV light shine on the catalyst, the reaction creates ions that decontaminate contaminants in the air and on surfaces. These ions are created when water vapor molecules are rearranged by the catalytic reaction. Basic PCO is minimally effective because the hydroxyl ions it creates are short-lived and don't last long enough to thoroughly decontaminate your living space. An advanced PCO, like our AHPCO® ionization, uses specific catalytic elements to produce a variety of safe, long-lasting ions that travel farther and deactivate contaminants longer both in the air and on surfaces.

What is bi-polar ionization?

Bi-polar ionization is a simple technology using two oppositely charged poles to split water vapor into positively charged hydrogen ions and negatively charged oxygen ions. Due to the imbalanced charge effect, these ions are drawn back together to reform as H20 molecules. Airborne particles, including dust, pet dander, allergens, mold spores, and even airborne droplets containing viruses will be drawn together and drop from the air. The primary deactivation of these contaminants is due to a molecular decomposition caused by positive hydrogen and negative oxygen ions interacting with them.

The iAdaptAir┬« uses a multitude of processes to decontaminate your air on a molecular level. Take advantage of HEPA and carbon filtration, AHPCO┬« and bi-polar ionization, plus UV light, to trap large and small particles and reduce contaminants.
