A:Answer Personally, I definitely would not purchase generic filters for your fridge.
Yes, they're cheaper, will fit your fridge, and perhaps state that they are better however, just read through the reviews and I'm sure you won't be impressed. Many users have complained about generic filters leaking, producing a fowl taste and/or odor..etc.
I've been using the LG branded filters going on 5-years with zero issues. So, for me, LG filters is the way to go.
