Scientific and public controversy over ionization claims
During the COVID-19 pandemic, scientists, engineers, journalists, and public-health organizations questioned whether GPS Air’s needlepoint bipolar ionization devices were effective under normal operating conditions. Critics highlighted the difference between high ion concentrations used in some tests and concentrations reportedly produced in ordinary rooms, while also raising concerns about possible negative health effects and by-products. Some schools and public bodies reconsidered or removed installations.
