Product review (5 stars): Don't Pay For OEM Samsung Filters
We have a Samsung 266AEPN French Door fridge, this filter works great.  I would say perfectly, but there is a bit of a leaking problem.  This only lasts for a day or so though, but it's still a bit annoying.  After the first day or two though, the leaking goes away.

Water from the fridge tastes fine with this filter with no chlorine or any other after-taste.  Buying in a multi-pack definitely saves money.

The filters include a sealing tube of lubricant, but I don't need to use them with my fridge.  This is the brand I've been using exclusively for over a year.
