Product review (5 stars): Our water is drinkable again!
We initially replaced our first filter with a Samsung branded filter. The filter that had shipped with our refrigerator was fine, but the new Samsung filter tasted awful. I'm not talking it didn't improve the taste of the water, but it actually added a really bad taste to it.  I kept waiting for enough time and water to pass through it that it went back to normal, but it never did.
Finally I ordered this replacement filter and our water is drinkable again. BONUS: it's half the cost of the Samsung filter!  Will definitely order this one next time.
