Product review (1 stars): DON'T BUY THIS FOR SAMSUNG. Doesn't fit PROPERLY.
Major design flaws in the AquaFresh WF294 that render this item a leaky mess, you can even see it in the video. When inserting the filter, You cannot turn it far enough to lock it in place, in the video you can see that the arrow is not perfectly lined up perpendicularly. This is because the union joint on the WF294 is almost twice as thick as the OEM filter and it can't seat fully in the receptacle. Also, the keeper flange on the WF294 is slightly thinner on the insertion side and therefor doesn't seat properly. Don't buy this unit, I'm still cleaning up from the mess it made...and I hope it didn't ruin my $2,000 fridge.
