Soft ionization has been proven to reduce airborne respiratory viruses in indoor spaces by up to 99.98%, according to a newly published study in the journal PLOS ONE. The study tested the effectiveness of soft ionization using bipolar ionization (NPBI™) to reduce the number of airborne respiratory virus particles in indoor spaces.
The results of the study showed that all ion levels tested rapidly inactivated airborne concentrations of respiratory viruses, with the highest levels of ionization reducing virus particles by up to 99.98%. Lead researcher Dr. Edward Sobek, Chief Science Officer at GPS Air, said, “Soft ionization using NPBI is an important tool to reduce contaminants, including respiratory viruses like SARS-CoV-2, Influenza and RSV, in the spaces where we live, work, and breathe. Using NPBI to distribute ions at the source of these contaminants provides cleaner air where you need it the most.”
The researchers designed the study to test viral concentrations and test chamber conditions that are much closer to real world applications than previous studies. “It is important to design tests as close to real world conditions as possible, to remove bias and not mislead consumers,” researcher Dr. Dwayne Elias explained. “This was not testing in a shoe box; our study was conducted in a large BSL-3 lab chamber using viral concentrations based on the amount of virus that an infected person can aerosolize in casual conversation.”
The results of this study validated a significant tool in the fight against airborne respiratory viruses. Soft ionization has been proven to be effective in reducing airborne respiratory viruses in indoor spaces, a critical part of every healthy building plan. This technology can be used to reduce the spread of airborne respiratory viruses, providing a safer environment for everyone.
