Product review (5 stars): Easy to use
Since I am a klutz when it comes to removing and replacing something like a water filter, I appreciate how easy this one is to use.  In addition, I only need to change it once every six months, since I am the only one using it.  I can tell when it needs to be changed because the flow of water diminishes over time.  My son uses the same kind of filter for his family of three and he needs to change his a couple of months earlier than I do mine.
