Product review (5 stars): Way cheaper than the brand name and works the same.
Perfect generic filter for Samsung fridges.  I cannot tell the difference between the one that came with my fridge and this one.  Water is super clean and  tastes great.

If you open your double door fridge and look in the dead center and all the way at the bottom, its hidden behind this little cap in the middle of the fridge.  Twist it and pull out.  Careful, there will be water in the old one.  Plug in the new one and run a few gallons of water to get all the intial garbage out of there.
