Is R/O water or Carbon Filtered water best?
RO Water, as that is 0ppm (or near to), carbon filtered should be just the ion exchange, CA , MG ions exhanged to something else, mostly NA.
But there is one type filter who do CA to MG.
Edit: Carbon filter is just , filter, no ion exchange)
Wrong info from me!
RO is still 0 ppm
RO is the best since closest to 0 ppms
RO is most like (unpolluted) rainwater
Separate names with a comma.
