HVAC colloidal silver is superior to the low voltage DC process in general
because of three things:

1. The HVAC process if done properly uses distilled water and never adds any
salts, resulting in pure colloidal silver without any toxic silver salts.
This may or may not be true of the DC process being used.

2. The HVAC process if done properly will result in a greater positive charge
on the particles, increasing stability and effectiveness.

3.  The HVAC process if done properly will result in smaller particles for any
specific PPM, resulting in increased stability and effectiveness.

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

I hope that answers your question.
