Product review (2 stars): Not What I was Expecting
They fit in place of the LG ones that I was replacing for a lower cost but I bought these filters specifically because they are described as bring NSF 53. However, I checked the box when I received them to find that they are only NSF 42 standard.

Update: I see white foamy and hard buildout around the water spout...which I never had before. They are definitely not filtering properly. This is after only two months of usage with two people in the household...definitely have not surpassed the life that is advertised.
