Works great,
change it every 100 gallons or when the water starts tasting slightly
metallic, indicating the carbon has loaded up with benzene, which
distillers also distill out of the water.

The CRC lists 15 substances with the same boiling point as water.
A simple still won't even remove alcohol or methanol, or acetic acid.
Of the hundreds of known chemicals with boiling points near water,
few, fortunately, are likely to be found in high seas water. Some
rivers are a different story. I would't trust some river water not to
attack gelcoat or aluminum. You wouldn't have the urge to put it in a
nice clean still. Distillation is OK but it costs a lot. In my
opinion, either RO or distilled water should be run through a carbon
filter. Gets the benzene and a lot more. Carbon ought to take out
'plastic taste' but I have not put it to the test.

The test is the TDS meter and electrical conductivity. Distilled water
is an insulator. These carbon-based chemicals you list attach themselves
very nicely to the carbon molecules in the activated carbon filter. That
filter gets quite hot in their presence during use, even at the tiny
trickle of water coming from a small distiller.

Even at 2000VDC my water is barely conducting. It's a very good
insulator after carbon filtration. Another indication of its purity is
it is very corrosive and simply guzzles anything that will dissolve in
it....which is what its use is in the human body.
