Product review (5 stars): What is required with my GE Refrigerator
It is easy to install - and to replace the old filter.  It seals quite completely.  My fridge has a "light" that lets me know that I need to replace the filter - you do need to run a lot of water through the new filter before that light goes off - but it does go off eventually - I gave up trying to do so at one time - and just started using it as I would normally and the light finally went off!
