Product review (5 stars): Decided to replace with a manufacture's OEM because of meeting specs.  Can't go wrong!
Almost bought a 2-pack from another vendor until I started reading the reviews.  The LG OEM filter is certified NSF/ANSI 42 and NSF 53 standards.  Some of other less expensive products don't necessarily meet BOTH standards for appearance and health.

Suggestion to all, check out the fine print to be sure it meets your definition of "direct" replacement :).

The less expensive filters sure did not meet mine.
