That is one long and complex article! My understanding from reading it is when the wall-mounted showerhead was put on “rain” mode, more small showerhead holes were involved and thereby creating more mist. The “massager” function used the larger holes in the center of the wall-mounted showerhead and created less mist and put less NTM in the air.

This is consistent with Dr. Falkinham’s recommendations to use a showerhead with large holes. Also, whenever possible, to leave the bathroom when the shower is first turned on and bacteria breaks off from the biofilm lining the pipes. Additionally, to make sure your window is open and the fan is on.

I live in an apartment building and this is not possible for me. I don’t have a window in my bathroom, nor a fan. So I tend to take short showers. And, I use a handheld showerhead on the massager setting (only large holds in center of showerhead are used) that I hold close to my body so it creates very little mist.
