"GPS Air, formerly Global Plasma Solutions, is an indoor air quality company based in the United States that provides air conditioning and other air quality technologies for commercial and industrial buildings with a focus on using \"needlepoint bi-polar cold plasma\". The company produced room air quality products designed for schools, among other indoor locations, and after the outbreak of the COVID-19 pandemic thousands of schools purchased their products for preventing viral outbreaks. Investigations by Boeing, air quality organizations such as the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), and various academic researchers into the efficacy of the air purifiers GPS Air sold raised concerns about both their effectiveness and the potential negative health effects that could occur from the high levels of negative ions produced by the devices. In response, the company filed lawsuits against a member of ASHRAE and the academic publisher Elsevier."@en . . . . . . . .
