Both of these "low-chlorine" systems use tiny beads of silver and copper that basically surrounded or encapsulated in ceramic.  Under a microscope, these beads or pellets like little sponges with lots of nooks & crannies.  As the water passes through them, the water comes in contact with the silver or copper. These are sometimes called ionizers.

Silver is a great "natural" bactericide.  In ancient times, silver coins were often put in barrels of water or jars of wine to keep them "sanitary".  Silver (in the form of ointments) is used today to treat many wounds that otherwise have a difficult time healing.

Copper is a "natural" algicide. Copper has been used to treat algae in swimming pools for decades.  Very small doses of copper are used to prevent or treat algae blooms in ponds, lakes or small reservoirs.  A little typically goes a long way.

The ceramic beads or pellets that contain the silver or copper, are terrific filters, filtering the water as it passes through down to about 1 micron (the size of large bacteria).  When combined with low, regular doses of chlorine or bromine, you've got good easy to maintain spa or hot tub water.

These ionizing cartridges have a typical life of about 3 to 4 months.  So whenever you change the water, just throw out the cartridge & replace it.

Compare these ionizing systems to other hot water care products.
