We succeeded in shooting a video that clearly shows the effect of CLEAN·REFRE inactivating E. coli. When we drop CLEAN·REFRE about 12 seconds after the video starts, you can see that numerous E. coli actively moving are inactivated in a moment. We have been using CLEAN·REFRE in the office for about eight years and have not had any flu. And there is no adverse effect of CLEAN·REFRE on our body.
In addition to the new coronavirus, we must be aware of the upcoming influenza virus.
