Product review (1 stars): Misleading sales pitch, not truly compatible with LG filters
These are not NSF 53 (health effects) certified, only NSF 42 (cosmetic effects).  The original LG filters are both NSF 42 and 53.  As such, these are not true OE replacements.  (If you have no idea what I'm talking about, Google NSF 42 and NSF 53 and compare the specs on the filters.)
