HVAC silver colloid in distilled water = LVDC silver colloid in
distilled water.

Mmmmm! How? What proof is there for this statement? How many electrons
does the HVAC system remove from the silver atom? Has anyone measured
the charge on an AC generated silver atom vs. DC generated atom. Can a
charge can be produced on silver atoms in any way other than by
removing electrons... I don't think so.
The first part of this statement needs to be true for the second to
have any meaning.

The LVDC process, if done properly will result in particles of a
similar size to HVAC generated colloidal silver.
The effectiveness of HVAC vs. LVDC colloidal silver is a 'moot point',
and along with other misinformation, is generally raised by HVAC
producers and vendors to further promote their product.
Well made LVDC silver colloid is as stable as HVAC CS, and is so at
far greater concentrations than is found in HVAC products.

> DC is good, but in general the HVAC process is better.

See above.

I hope this corrects some misinformation.
