The “corona discharge” ionization technology from another vendor that Boeing also studied did emit ozone at levels that “exceeded regulatory standards.”Ī University of Arizona lab test described in the Boeing study found that the GPS device showed a 66.7% inactivation of a common cold coronavirus on a surface after an hour of exposure at up to 62,000 negative ions per cubic centimeter. Notably, Boeing’s tests in Huntsville detected no hazardous ozone gas from the GPS unit, the report says. At the end of 30 minutes, “the overall average decrease in active virus” was more than 99 percent. The test report shows it was conducted in a sealed, 20-by-8-foot chamber, with airflow speeds of 2,133 feet per minute - or about 24 mph. That study looked at the effect of the ionizers on the virus that causes Covid-19 when used on aluminum, a type of plastic called Kydex and leather. It completed a study of two devices - powered by GPS technology - that another aviation company now markets to clean the air and surfaces in planes. GPS pointed to another study, one conducted in the weeks before Boeing began its study in September, by a third-party lab. “It should just raise flags for absolutely everyone.” 'No reduction' in bacteria “This is totally damning,” said Delphine Farmer, a Colorado State University associate professor who specializes in atmospheric and indoor chemistry who reviewed the Boeing report. They include one California superintendent who cited the lawsuit and switched off that district’s more than 400 GPS devices.įor worried parents and academic air-quality experts who regard industry-backed studies with skepticism, the Boeing report heightens their concerns. The controversy is getting the attention of school officials from coast to coast. In April, a covid-19 commission task force from The Lancet, a leading medical journal, composed of top international health, education and air-quality experts, called various air-cleaning technologies - ionization, plasma and dry hydrogen peroxide - “ often unproven.”īoeing said in its report that with ionization there is “very little external peer reviewed research in comparison to other traditional disinfection technologies” such as chemical, UV and thermal disinfection and HEPA filters, all of which it relies on to sanitize its planes. Many schools used federal funds to purchase the products. schools had bought air-purifying technology, including ionizers. The plaintiff’s case cites a KHN investigation that found that more than 2,000 U.S.
“But it is devoid of any concrete, specific allegations plausibly alleging that GPS made even a single false or deceptive statement about its products.” “Plaintiff’s Complaint throws the proverbial kitchen sink at GPS in the hopes that something might stick,” the air purifier company says in court documents filed May 24 as part of its motion to dismiss the proposed class action.
