Product review (2 stars): Be Aware: Does Not Filter Impurities. It Just Makes Water Taste Good
Be aware: this product doesn't filter ANSI/NSF 53 impurities like mercury, lead, and other toxins. It only meets ANSI/NSF 42, which just makes water taste good.

The actual Samsung replacement filters sold at Lowes, which is a retailer of Samsung refrigerators, meets both standards and are DA29-00003G. I bought one two weeks ago and installed it. It works fine.
