Just to clarify.
The WHO (world health
organization) drinking water
standard is 500ppm and the US Military ppm standard is 750ppm. Most water maker companies I know of say that when you reach 500ppm, you should be changing your RO Membranes or look into cleaning
them. (I'm not a fan of cleaning
personally). If a client of mine had a TDS of 500 or more, I would be sending out a replacement membrane.
