If someone has test results showing their air cleaners work as claimed, they should publish them. Peer review is key to validation. In general, adding ions, plasmas, & oxidants to indoor air creates health concerns. See this recent review and refs:

These companies are coming out of the woodwork selling super expensive devices to schools and businesses. Their technology has not been validated in any acceptable way. They claim they have proven it works on web sites where anyone can say anything they want. This is not OK.(2/)
They are taking advantage of schools desperately trying to protect kids during a pandemic, thinking if they spend 10 times more, they will be protecting them even more. Not the case. Simple HEPA filtration and ventilation are all one needs to clean indoor air.
Just spoke with someone who has been totally conned by these people. They have limited resources, are desperate to protect themselves, and their family and friends…they have no idea how the science works and have blindly trusted these companies. Sickening.
