I purchased a used refrigerator, and was upset that the water pressure wasn't there.  I looked on forums and found that changing a filter can sometimes do the trick.  These filters are priced very well considering the manufacturer wants double the cost!  So we tried this out and BOOM!  Our water pressure is where its at.  We used to buy gallon jugs, but feel this is more economical and since its filtered anyways, why the heck not?!
