Decontamination Effect of Hypochlorous Acid Dry Mist on Selected Bacteria, Viruses, Spores, and Fungi as Well as on Components of Electronic Systems

This study looked at how a dry mist made from hypochlorous acid can kill germs like bacteria, viruses, spores, and fungi. It also tested if the mist harms medical devices (like finger pulse oximeters) or small computers (Raspberry Pi Zero). The researchers used different strengths of the mist (300, 500, and 2000 ppm) and sprayed it in special test chambers. They ran two types of tests: one with 30 misting cycles and another with 90. Each cycle included spraying the mist, letting it work on the items, and then cleaning the chamber. The results showed that the mist reduced the number of harmful microbes. At the same time, the devices and electronics kept working properly, and the mist did not get inside them. Overall, hypochlorous acid dry mist was found to be effective for disinfection and safe for use around sensitive equipment.
