A recent study conducted by scientists at Ingogen provide us with exciting clear insights into the efficacy of HOCl in the air and on surfaces. Herewith an excerpt of the study.

“HOCl solutions administered via a free-standing, portable ultrasonic humidifier produces a light fog covering up to 5,000 square feet. The mist consists of aerosolized particles, 2-4 microns in size, which hang in the air, creating a very slight haze, while also effectively coating surfaces without wetting (“dry-fogging”).

In an initial fogging experiment conducted by Inogen a US based HOCL provider, they continuously injected an EPA-approved surrogate for the COVID virus (Human Coronavirus OC43) along with a fogged HOCl solution. After infusion, viral concentration measurements were taken at 10, 20 and 30 minutes. This means fresh virus constantly replaced what was killed. Thus, the air in the room was never completely without live virus.

Second, HOCl quickly dispatches pathogens more difficult to kill than Coronavirus. So, in order to seriously test the effectiveness of the fogging process, an enormous viral concentration of about 33,000,000 times that of a sneeze from a SARS-CoV-2-infected person was injected into the air on a continuous basis.

Even with those two extreme challenges, before the first measurement at 10 minutes, the misting procedure was established and an average equilibrium point of almost 95.6% kill was maintained throughout the 30-minute trial, effectively counterbalancing an exponentially increasing virus load in the room. Further research into efficacy of viral kill is in process. Below (fig. 2) is a graph of the balanced equilibrium with the blue line tracking the viral injection and the green line tracking the kill rate.

In the context of the pandemic health crisis, these results offer a promising advance in mitigation strategy, available while people are congregating together in a room.

In a second fogging experiment, the virus (again, Human Coronavirus OC43) was placed on a glass plates surface and the room was continuously fogged in a manner simulating a standard workday, resulting in a >99.999%* reduction of the virus.

Vaporized HOCl dry-fogging will attack and kill viruses both in the air and on surfaces.

The CDC has acknowledged spread of the virus both through surface contact and from transmission through the air, so talking could result in droplets staying airborne for 5-10 minutes, thereby resulting in viral transmission.14-21 Smaller, aerosol sized droplets have been shown to stay suspended for several hours and can carry viruses such as SARS-CoV-2. But vaporized HOCl, when used in dry fogging, effectively attacks and kills viruses both in the air (droplets or aerosolized) and on surfaces within seconds to minutes. “

Coronaviruses such as HCoV-229E and OC43 are frequent causes of respiratory illness throughout the world, and SARS-CoV and MERS-CoV represent significant public health threats.
