I have a handheld TDS meter. When i check my RO/DI water I get a reading of 0. I have tried this on several occasions and it is consistent. I have only had my RO/DI since March and I only do 5 gal. or so a week. So it is probably reasonably accurate. Just now I checked my NYC tap water and it was 36, so that sounds about right I guess. But when I checked the water from my Pur water filter it measured 40! I tried it several times and this was very consistent.
The Pur filter is only 3 weeks in use and according to their little meter on it is not even close to needing to be changed.
Does this make any sense?
