How it work

History Of Bipolar Ionization

Bipolar ionization has long been prevalent in much of Europe. According to Business Insider, "Bipolar ionization first came to the United States in the 1970s as a tool to control pathogens in food production. It was effective during the SARS outbreak in 2004 and more recently during outbreaks of MERS, norovirus and various strains of influenza."

Recent advances have made the device significantly cheaper and easier to install, so many companies are now testing the technology against the novel coronavirus in their own facilities.

How Does Eddaair Bipolar Ionization Work Within an Air Purifier?

Eddaair uses DBD (dielectric barrier discharge) technology to ionize air in the environment of external high voltage electric field, so that the air produces high-energy positive and negative electrons. Negative ions contain an extra electron, while positive ions lack one, leading to an unstable situation. To return to stability, these bipolar ions seek out atoms and molecules in the air with which to exchange electrons, effectively neutralizing particulate matter, bacterial and viral cells, odor gases and aerosols, and volatile organic compounds.

The ion tube produces alarge amount of positive and negative ions.

Charged ion cluster active attack viruses and bacteria.

Destroy cell membranes, viruses DNA and protein.

Make it lose activity quickly and be killed.

Advantages of Eddaair Bipolar Ionization

Bipolar ionization offers many benefits such as:


Reduction of dust and mold particles. Plasma that binds with contaminants, grows in size and mass and falls to the floor, or returns to the filter, making them easy to clean from the air we breathe.


Neutralize odors. Plasma breaks down odors at the source and removes them.


Control chemical and VOC gases. Plasma breaks down toxic gases and compounds from hazardous chemicals such as cleaning products, pesticides, paint, solvents, mold and more.


Kill bacteria and viruses. Because bipolar ions negatively affect the DNA of bacteria and viruses, you will protect the people against disease and epidemics.


Low cost maintenance. There are no filters to change or collectors to clean. Just replace the Plasma tubes every 2 year.

Compared With The Reactive Air Purification Methods

In laboratory testing, bi-polar ion systems have shown significant ability to reduce pollutants. The active process of the ions saturating the room to get to the source of pollution shows high efficiency compared to passive technologies that have to carry the pollution to the device to be affected.
