This filter keeps my water tasting like nothing -- which is exactly what water should taste like.  I looked at the less expensive "knock-off" filters, but I noticed an important distinction:  Most aftermarket filters say they meet NSF/ANSI standards, but they do not say they are certified.  The LG filters say they are tested and certified by NSF against the NSF/ANSI standard.  This is important, to me.  Any manufacturer can say they try to meet a specification -- but a part that is independently verified as meeting the spec will earn my preference.
