Product review (5 stars): Solid product, meets both ANSI/NSF 42 and 53
These are the real deal - they meet both sets of ANSI/NSF standards (42 and 53) where many of the lower priced competitors only meet NSF 42, which is the taste and color specification, not the water purification and contaminant elimination (health related) specification.

They fit as they are designed by the manufacturer to work in Samsung refrigerators.
