Product review (1 stars): Always an issue
I've replaced the water filter two times thus far and both have had issues. Original filter that came with refrigerator was only one that worked without any issues.

First replacement filter:
Bought at store and flushed it with 3 gallons worth of water as per the instructions. Everything seemed fine until I noticed the water dispenser was dripping water slowly all night (would completely fill up the tray area). After about two weeks, it quit dripping water. This filter also didn't dispense water as fast as the original, I've seen some other people mention this issue with a batch that was sold at a large home improvement store (which is where I bought mine from).

Second replacement filter:
Needed one again so bought locally ($$$). Did the required 3 gallon flush, everything seemed much better than the first replacement. This new filter had good water pressure and didn't drip like the old one. However, after not using the water dispenser for about two hours and then getting some water, there was an odor that had a slight sulfur/pee smell.

So I flushed the filter with another 2 gallons of water. Same result, tastes fine after flushing but let it sit for awhile and the odor comes back. I waited a few days to see if it would go away, no luck. Decided to return it and buy another replacement filter from a totally different store hoping I got a bad one. Latest replacement filter has the same odor and it's not the tap water causing it as I never had this issue till I replaced the old filter (even the tap water doesn't smell).

Not sure if Samsung has a bad batch of these things going around or in certain areas or if they changed the filters in any way lately that is the root cause of this. However, I find it kind of strange that every time I get a new replacement filter, there is always an issue it seems.
