As Schools Spend Millions on Air Purifiers, Experts Warn of Overblown Claims and Harm to Children

 


Last summer, Global Plasma Solutions wanted to test whether the company’s air-purifying devices could kill covid-19 virus particles but could find only a lab using a chamber the size of a shoebox for its trials. In the company-funded study, the virus was blasted with 27,000 ions per cubic centimeter.

In September, the company’s founder incidentally mentioned that the devices being offered for sale actually deliver a lot less ion power — 13 times less — into a full-sized room.

The company nonetheless used the shoebox results — over 99% viral reduction — in marketing its device heavily to schools as something that could combat covid in classrooms far, far larger than a shoebox.
