Distilled Water

I put a reverse osmosis system under the sink. That way I have distilled water on tap for my salt water fish tank and my humidors. Mine was a high volume one and cost about $250, but they can be had lots cheaper.
We refill our water bottles from it, too. So we really get our money's worth.

Purified water via filtration(reverse osmosis) is not the same as distilled water.

I know the process is different, Bob, but is there a difference in the finished product? I'd think zero stuff in either one is equal, what's the diff between the two?

RO forces water through openings so small that many minerals cannot make it through and are thus filtered out. The distillation process (boiling and condensing) is widely considered 100% pure, but is not 100%. In fact RO isn't 100% either. For drinking water quality purposes they are pretty much a wash. RO is widely considered more cost effective, probably because you don't need the energy to boil/evap the water and condense it again. That is why a lot of people have RO systems and not distilleries (not for water any way).

There is... I did these tests with a water tester a month or so ago for a similar thread.

TDS: Total Dissolved Solid

Tap Water:
From Faucet: 240

Spring Water:
Ice Mountain: 160

Reverse Osmisis
HyVee: 20

Distilled Water:
Great Value: 1

The names of the brands under each category is just a popular source here where I live.
