"Unfortunately, product testing has not shown silver impregnated AC to be much more effective in controlling bacteria than normal AC filters. Only in the first month of operation did there appear to be any advantage to using an AC filter that contained silver."

"There is a lot of talk on the effectiveness of traditional silver impregnated carbon in treating bacteria growth. In a study performed by North Dakota State University in February 1992, it was discovered that after one month of use, the silver impregnated activated carbon filter had practically diminished its effects on prohibiting bacterial growth. All silver ion impregnated filter"

"Some filters are impregnated with silver to try to prevent bacterial growth, but studies indicate that this practice makes little difference in reducing bacteria. Any advantage seen from the silver is only apparent in the first month of use"
Notice they refer to
a)"silver
ion impregnated filter"
b) "prevent bacterial growth" as opposed to algea growth which is what you really should worry about...and you will use copper for that.
Silver does not dissolve in pure water, even in polluted water they will use electrolysis to release the ions

"Copper-silver ionization is brought about by electrolysis. An electric current is created through copper-silver, causing positively charged copper and silver ions to form."
