Our units utilize two different technologies. AHPCO and Bi-Polar. The AHPCO technology will produce low ozone and ionized hydro peroxides. So you are not only removing particles from the air by having negatively charged particles attaching to positively charged particles and falling out of the air but you will also have the ionized hydro peroxides landing on surfaces. They will sanitize the surfaces for you as well. The Bi-polar technology uses electron voltage to create positive and negative ions that attach to larger particulates and also help to remove them. This combined action will also deactivate mold and spores, prevent biotin buildup, kill bacteria, viruses, break down VOC’s and chemical, and kill odors. This is very sophisticated technology.
