Product review (5 stars): Drinking water filter
We bought this to go along with the flush valve kit also by culligan.  Our fridge is a ice only dispenser, so the flush valve was a huge plus in allowing us to flush the filter and not having to throw out ice for weeks.  The fitler itself is very easy to install and changing the filter is a breeze.  You just turn the filter about 1/4 of a turn and it pops out as well as automatically shutting off the water, so no leakage!

We live in the city, and with this filter we have not had any issues with our ice adding that "swimming pool" taste to our drinks.  I can't say on how well it filters, but it filters well enough for us.

Another note is the flow rate on this filter.  I've had some fridges where the water comes out at such a slow trickle due to the filter that it takes a long time to fill a glass.  With this filter we got quite a stead flow of water through the flush valve that we were able to fill a 5 gallon bucket in about 5 minutes, so this should not impair your fridges water flow at all.
