Guys, I have had a home RO filter for 30 years. It get replaced once a year. At the end of the year the water has about 300 non-water parts per million. After it is replaced this is 3 per million. Our chemistry department has a much higher quality RO device. They certainly were not impressed with my home results but did not mention what theirs yielded.
Hdm, assuming that you meant to add distillation to reagent water, I cannot imagine that adding salt back in as a softener would be used.
Cello, my tests also show that ultra pure water is superior at least as a final rinse to RO water.
