Disinformation

Contrary to popular belief, our products are NOT Ionic. 

It is impossible to make the Metalic Ions in a Colloidal Solution

The truth:

Well, most of what you'll "learn" is sales hype or repeated ignorance handed down without context...some is even partly true.
"Technically" an ion is a particle because it has mass and takes up space, but the technicality is often used to mislead.

The silverpups and ALL generators that use electricity and water make ONLY ions and  silver ions only come in one size...one atom minus an electron.
Particles form FROM ions later, mostly in the Nernst Diffusion layer at the electrode surface/ water interface and according to environmental conditions such as concentration.
If the concentration is higher than the solubility limits of silver ions in water,the ion is forced to combine with something to make a particle.
Only those ions that find an electron become "silver" particles. Electrons can be picked up at the air/electrode interface and from glass acting as a capacitor/ [very inefficient] solar cell collecting electro-magnetic radiation. There are no "free"electrons in a liquid. only electron imbalances as ions and anions.
Some of the hydroxyl anions OH[-] will combine with  silver ions to form a silver hydroxide particle or with dissolved oxygen, to form silver oxide....both, byproducts of electrolysis,
Hydroxyl rich water is also known as "alkaline water"
If the current is kept low, the oxides and most of the hydroxides form and stay on the electrodes where the SWAP current reversal phase re-converts most of it back to ionic silver.
The more particles in a given volume, the higher the odds of them growing bigger and they don't come in one size, but ranges of sizes with the vast majority of the silver still as ions.
Current control controls current density on the electrodes and keeps that concentration down in the diffusion layer so fewer and smaller particles tend to form, but the water itself plays a role too and water is highly variable.
Particle Size

The machine itself...doesn't make "particles"...at all.

No generator that uses electricity and water makes "particles" AT ALL.

They make ions and nothing BUT ions and silver ions only come in one size or they aren't silver.  No "particle" of silver can possibly be smaller.
A silver ion, by definition: A single atom minus an electron at 0.000252 microns diameter

0.000252 microns = 0.252 nanometers

If anyone answers your question " What size are the particles this machine makes? " with a number, they are either liars or suffer from ignorance.
With 85% to 97% of the silver being ionic, smaller than a single atom by definition and nothing smaller possible, does it really matter?
Particles bigger than around a couple of microns settle out, by definition, not "colloidal".
Leave those on the bottom.
