Product review (4 stars): Fits my Samsung Aqua-Pure Plus Hook-Up Perfectly
I have two Samsung refrigerators (model RSG257AARS) that use this size filter.  I purchased several of this brand of replacement filter to make sure I have back-stock for when the filter expires.  This one is identical to the Samsung brand filter and costs about $7.00 less.  This brand also costs $5.00 less than another off-brand I purchased at Lowes.  This filter was easy to install and it fit perfectly. It appears to be working just fine and the water tastes great.
