I think soil is just too dense for UVC. Works well on hard surfaces after a good attempt at sterilization via cleaning first with
physical methods. Hospital settings. Running UVC post cleaning surfaces, it will do yet another air and surface sterilizing.... with all surgical instrument in a heat/steam sterilizer. It just cannot sterilize the slightest shadow. A grain of soil will have a shadow side, clearly unsterilized. Manufacturers did run wild and took advantage of consumers. Still at it. It has been abandoned by all applications for covid. A speck of salmonella raw chicken skin on your counter will not be sterilized no mater how long it is under UVC. (it has a shadow side). The side sitting on the counter. Think microscopic. Use soap, (counters). Use heat, (soil). 2 trays of soil in foil pans with foil on top....easily will fill two seed start trays. Easily sterilized in your oven. An operating room is doing all they can to prevent secondary infections. And the recovery rooms. Heat sterilized sheets, etc. I do agree that air sterilization is effective passing multiple times through UVC purifiers. |
