Why do you assume that the materials passing through the filter
are toxins? Perhaps they're nutritional carbohydrates? Such
assumptions and wording seem to show a bias against RO filters
in your response. In any case, you probably get a good dose of
the same 'toxins' in your city drinking water after the chlorination
has killed the bacteria.

AS it was explained to me, these boat RO systems, to be small, use very
high pressure on the membrane, as opposed to large commercial systems
like a public utility would use in a purification plant at low pressure.

Must be different from our greenhouse RO filter system, then. It
runs off the 40 to 65PSI from our well pump and tank.

This high pressure traps the bacteria against the membrane, where I
suppose it's like his little head is stuck in a hole his body can't fit
through, a crude cartoon-of-the-mind's-eye.

Now trapped in a high pressure environment, at some point, the bacteria
explodes, releasing its internal load of really small toxins onto the
surface of the membrane where it can, because of its tiny size crude
molecules pass through the membrane with the H2O, contaminating the
outlet water. The key, I'm told, is the high pressure, which rips many
biologicals apart into tiny pieces. I don't see why this is not a
possible scenario and a source of possible sickness for the drinkers.

You still haven't shown why you think the bacterial fragments
are 'toxins'. Toxins are generally considered to be special-purpose
chemicals released by an organism for a specific purpose.

Toxin:
"A poisonous substance, especially a protein, that is produced by living
cells or organisms and is capable of causing disease when introduced
into the body tissues but is often also capable of inducing neutralizing
antibodies or antitoxins"

This definition doesn't seem to include fragments of dead bacteria.

We're still talking about FILTRATION. Anything small in molecular size
passes through because the holes have to be big enough for water to pass
through in large quantities. There are a lot of such molecules. Water
is a fairly large molecule because of its oxygen atom's atomic number.
I just don't think it's the holy grail the sales brochures profess it to
be. Dissent against the RO community is treated the same way as someone
who wonders how 6,000,000 bodies in Nazi concentration camps fit in such
a tiny space...to be attacked at all costs!

OK. I invoke Godwin's Law.
