Arc eliminates 99.99% of surface and airborne pathogens - including those that cause the coronavirus and seasonal flu. UV-C has been proven to work on bacteria, viruses, fungi, and mold. So not only will Arc eliminate the toughest pathogens, including antibiotic-resistant strains, but it will also destroy fungi and mold - eliminating the unpleasant smells that typically accompany mold spores and helping prevent future mold from forming.
Here is an example of how effective the Arc is at killing some dangerous pathogens (data provided by a third-party test):
Additionally, Pathogen Cards can be placed in the room before running a cycle. The yellow photo-chromatic ink circle will change colors depending on the amount of exposure to UV-C light. If the center of the UV-C Dosimeter changes to orange, it means that a level of energy lethal to MRSA has been delivered. If it changes to dark pink, it shows that a level of energy lethal to C.Diff has been delivered. There are official tabled with more information on the killing levels of different microorganisms. You can use these periodically to validate the efficacy of the device or to test how much light is being delivered to certain areas of the room.
