Product review (5 stars): Easy to install, works as it should
It came in a box with instructions (not that you really need any). There were stickers of the months including which you apply so you know when it was installed/needs to be replaced. It attached simply by turning it. The instructions say run water through it for 6-8 minutes or 3-4 gallons before drinking which is normal for all manufacturers of filters. What else can I say, it does what it's suppose to do how it's suppose to do it,
