Product review (1 stars): Replacement for..." means it is maybe not the same, probably a counterfeit part
"Replacement for..." means it is not the exact same as a Samsung filter. Bought 3, 1st one leaked a little - so put in 2nd one - AAHAA!!! it worked. Just installed the last one, it leaked like a sieve, over a gallon a day. Further investigation shows they incorrectly noted this model # was correct for my fridge. It is a WF-101. Correct model # for a rf23j9011sr ref is HAF-CIN. It may work great in the correct refrigerator , but not in mine.
Added: Seller refused to resolve this issue. Problem is that their product page clearly indicates that this is a Samsung named product. The box clearly shows "SAMSUNG" and ref. # rf23j9011sr is a correct application for this filter in the referenced Samsung refrigerators. Upon receiving order, the filter is id'ed as a WF-101 NOT the correct filter for a Samsung Ref. (rf23j9011sr). Upon contacting Samsung, they tell me that the correct filter is HAF-CIN and what I was sold is a counterfeit part that would damage my ref. This ad is at best, misleading - and could be described as fraud - especially since it has resulted in about $500. in damage to my hardwood floor in kitchen.  Surely AMAZON policies  would not condone this fraudulent activity.&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Replacement-Water-Filter-Cartridge-for-Samsung-Refrigerator-Models-RF23J9011SR-AA-RF26J7500WW-3-Pack/dp/B01F89ZMD2/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Replacement Water Filter Cartridge for Samsung Refrigerator Models RF23J9011SR/AA / RF26J7500WW (3 Pack)</a>
