Hi, your question is a little off-topic for this particular discussion, but I'll give you a quick answer about the Berkey Gravity water purifier. None of their available filters, including the ceramic version, meets the requirements for removing mycobacteria from water.
To remove mycobacteria, the filter must remove particles of .2 microns or smaller. The best Berkey filter is rated to remove contaminants down to .9 microns. Further, all of their filters contain charcoal, which can be a breeding ground for mycobacteria.

So, no, a Berkey will not provide NTM-free water.
