It depends on how the distillation is done, and what condition the
still is in. If the water in the boiler is boiling rapidly, particles of
dirty water or scale can be blown into the condenser. For really
pure water, you have to distill 3 times in glass, with the last still
running at a low heat so it is just evaporating from the surface
without boiling. I don't know how ion-free the water needs to be
for EDM, I suppose it depends on the voltage used.
