Replacement 6 months.
This in my well pump cold inlet line. It is between sediment screen and the house Line input as a second - Post sediment filter. Allows open back flush of the sediment screen. This Cold water inlet filter was added in line to protect the DHW source. Added this household protection from any possible fines in series with a descaling filter at the point of use heater. Extends the flushing cycle on the heat exchanger to once a year. I change this every six months. Put it on subscription delivery and I never forget to change it.

Not 3M Quality
I could not find a genuine 3M replacement cartridge on Amazon even though I bought the complete unit here. This seemed to be the cartridge every one was using but I found it not to provide nearly as soft of water as the original 3M made unit. Perhaps it prevents scale buildup but the water is not soft. As I am using it to protect a tankless water heater, I will replace it with the genuine article.
