Product review (3 stars): Have not used it yet
I bought it after the filter light came on (6 months to the day). In my house I'm on a well. I have two inexpensive pre filters for the expensive whole house filter. For the refrigerator, I kept the inexpensive under house inline icemaker filter when I bought the new GE refrigerator. Unless there is something I'm unfamiliar with, I'll let the expensive GE filter stay in place until it clogs or the water starts to change in taste. I'm sure I'll hear from the experts now.
