Product review (5 stars): LG filter fits Kenmore Elite!
I knew my Kenmore refrigerator (3 door with ice/water in door) was made by LG but this never really meant much until I went to purchase replacement filters for the Kenmore - and the cost was roughly $60!!  So - I did some research and found that the comparable model LG refrigerator also has the same filter - and what do you know, it is less than 1/2 the price of the Kenmore brand filter.  I cannot tell a difference in the water quality by taste.  I do know that there are even less expensive filters but wary of the quality since saw some reviews claimed broken o-rings.  I didn't want a knock-off but rather a more reasonably priced filter if it is to be changed approximately every 6 mos).  Same goes for the air filter...which is priced about $30 for Kenmore and about 1/2 for the comparable LG part.
