Product review (1 stars): Misleading: NOT NSF/ANSI 53 certified
The bullet points are misleading.  The OEM Samsung filters are BOTH NSF/ANSI 42 and NSF/ANSI 53 certified.  This filter is only NSF/ANSI 42 certified.  This is a big difference in quality.  NSF/ANSI 53 addresses the reduction of specific health-related contaminants such as lead and giardia.  This may not be a big deal for some but an important detail for me.  The reduction of lead provides peace of mind with kids in the house.  I give it one star because the ad is misleading using the statement "Costs less than Samsung without compromising any quality or flow rate."
