Airborne and Surface Microbial Reduction in Real-World Spaces
Summery:
Independent research conducted by Panasonic evaluated the use of hypochlorous acid (HOCl) atomization in occupied indoor environments and found measurable reductions in airborne and surface-level microorganisms.
View Study
In a real-world classroom setting, HOCl atomization was associated with an approximately 85 percent reduction in airborne bacteria compared to a control space without the technology. Laboratory surface testing further demonstrated a 99.9 percent reduction of select bacteria, including Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa.
The study also observed reductions in fungi and mold-related contaminants, indicating broader air and surface hygiene benefits beyond bacteria alone. Panasonic has reported continued research into hypochlorous acid technologies over multiple decades, including evaluations related to viral and microbial suppression in indoor air environments.
This research was published by Panasonic as part of its ongoing indoor air quality studies.

Effective Airborne Virus Reduction at Occupied-Safe Levels
Summery:
Comparative research indicates that hypochlorous acid (HOCl) can reduce airborne viral load at significantly lower concentrations than harsher gaseous disinfectants, making it more suitable for use in occupied indoor environments.
View Study
In a controlled chamber study evaluating airborne influenza virus and SARS-CoV-2, low-concentration HOCl mist achieved an approximate 99 percent reduction in infectious virus within 5 to 10 minutes at levels consistent with human occupancy. In comparison, chlorine dioxide and ozone required substantially higher concentrations to reach similar reductions, exceeding typical workplace exposure limits.
The findings support the use of HOCl as a gentler, lower-exposure option for airborne virus mitigation under normal indoor conditions. The study also noted that effectiveness was influenced by airflow and humidity, reinforcing the importance of proper room circulation for even distribution.
This research was published in Food and Environmental Virology and focused on comparative airborne virus inactivation methods.
