These are great!  We put one in and it fit perfectly and makes great tasting water.  It doesn't leak!  When you go to put one into the refrigerator filter space, make sure it is engaged in the filter spot and turned clockwise (it is a little difficult to turn) into place so that it is locked into place and there are no leaks.  If you have the model number of your refrigerator, there are probably 50+ that this filter fits.  My refrigerator is 12 years old and I was able to find it on the list. Refer to your owners manual if you can't find the model number inside of your refrigerator door.  I will definitely purchase these again.  They are a fraction of the cost of the manufacturer replacement filter.  And the water tastes wonderful!
