Our units utilize two different technologies, AHPCO Cell technology & Bi-Polar Ionization technology. 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. Our technologies create a similar effect as being right beside the ocean or in the mountains at a high altitude. You will have the cleanest air possible indoors so you can Keep Calm and Breathe On every single day.
