* The study tested the humidifier's effectiveness using weakly acidic electrolyzed water (WAEW) and found that it significantly reduced attached bacteria and airborne microorganisms within 60 minutes.
* The volatilization of hypochlorous acid (HOCl) was effective in maintaining disinfection levels in the indoor space, with a notable decrease in bacterial viability and airborne pathogens observed over 180 minutes of operation.
When a hypochlorite solution is ultrasonically fogged in a room, free chlorine, i.e., HOCl and OCl, reaches various positions in two forms: fine fog droplets and gaseous hypochlorous acid(HOCl).
