Reducing Exposure to Nontuberculous Mycobacteria (NTM)

What about an instant hot water dispenser? I think the water can be kept at 140-200 degrees, mine produces up to 60 cups near boiling water per hour. Do you think the water would have mycobacteria?

Here is my layperson's take on this question.
According to a couple publications (which I cannot seem to copy right now) MAC & MAI are killed by 5 seconds of exposure to temperatures of 70C (about 170F). At that temperature, formation of any biofilm to harbor bacteria would be very limited. It would seem this would limit the amount of mycobacteria in the water.

Other considerations would be the frequency and cost of filter replacement, and how to clean the tank regularly.

This is neither a scientific opinion, nor a recommendation, simply some things to consider. If you are considering it, more research into the safety and a discussion with your pulmonologist would be warranted.
