I repeat: hypochlorous acid is a miracle. HOCl solution can apparently be nebulized and inhaled as a prophylactic (CW: animal testing)

"In this report, we establish through independent laboratories that the SARS-CoV-2 virus is rapidly inactivated by exposure to HOCl, as is poliovirus – a far more difficult virus to inactivate and often the gold standard for virucidal assessment. Inhalation of a microaerosolized fog of that same virucidal HOCl solution by rodents using the US EPA’s acute 4-hour inhalation toxicity protocol later provided observational, physiological, gross pathological, and histopathological evidence that showed pulmonary exposure of 52ppm HOCl to respiratory epithelium did not result in any difference when compared to control animals. Also reported are the chemical and antimicrobial characterizations of the HOCl microaerosols reportedly used as SARS-CoV-2 prophylaxis within the United States and elsewhere during the pandemic lockdown."

This also implies that you could stick it in a humidifier and disinfect the air of a space that someone infectious may have recently left, in addition to (or as an alternative to, if unavailable) air filtration

Purchased for 25 cents from a very, very old vending machine that was for sale at a local flea market.

I dont think I'd recommend using it.
