Don't just get out the biology book. Read it. Osmosis is transport of the
water across the membrane. The salts and organics don't move across it,
which is why it works.


Before plunging into RO, though, explore whether you need to get rid of the
natural organic ingredients in the water supply, and whether carbon filters
will do it for you.

                                Wow,

Get out a biology book.  Osmosis is the transport of salts and other ions
across a membrane.  Ions, especially salts, will always move from the higher
concentration to the lower concentration.  I think the guys are correct in
suggesting there is an
ulterior motive for suggesting softened instead of DI.
