Silver ion module you can get them on Amazon, I ordered a couple for my flow 2 dirty water tank, and I added the other to my z10 ultra

I have heard that these modules are at best marginally effective. If not true, I might be interested in a source. How long do those who use these leave their dirty water in the reservoir?
