Airborne Disinfection by Dry Fogging Efficiently Inactivates Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), Mycobacteria, and Bacterial Spores and Shows Limitations of Commercial Spore Carriers
****!!!! "Successful airborne disinfection of larger rooms by aPAA-HP is mainly influenced by surface temperature differences." "minor condensation occurred on a few germ carriers and some horizontal surfaces of the room fittings, especially those with slightly lower temperatures." "its germ carriers failed to reach the required 4-log10 reduction at locations with elevated surface temperatures, e.g., on illuminated ceiling lamps at locations 4 and 23 (in total, there were 13 fluorescent tubes in both rooms) and on the wall and floor next to an autoclave or a tissue digestor at location 10 or 19, respectively (Fig. 3a and andcc and Table S4). The data loggers, necropsy equipment, room surfaces, and electronic components remained unaffected during all testing and validation runs."
