Product review (3 stars): SGF-LB60 is the correct replacement
First of all I had to give a star for these but haven't used them yet.
You have to read and compare all these filters..... the differences are amazing. I haven't use this filter yet but am going to order one a see for myself how they stand up to the original LG and Sears filters that cost $10 to 14 dollars more.  The key in the differences between this filter and the SGF-LB60 which are still so much cheaper then the originals is, the B is important because it is the same as the higher priced replacements that remove more such a cyst. the original filters come in two type, A and B at the end of the number, the filters with B at the end is always more expensive and filters more. Be very carful and make sure you do research to get the correct one. The SGF-LA50 is just like the cheaper original filter that filters less and ends with A.
