Product review (5 stars): Please read this! Excellent value, but don't buy them here
UPDATE: I bought a pair of these about a week ago and installed one of them. Water now shoots with as much pressure as when we first got the fridge and it tastes just as good. The peace of mind of having plenty of safe drinking water without the severe waste of water bottles as my family had in the past is indescribable. Remember to change these every six months or when the indicator light turns on. Not much else to say except to remember to reset the water filter indicator. To do this, after removing the old water filter and installing the new one, reset the indicator light by pressing and holding the "Alarm / Hold for 3 sec For Filter Reset" button for 3 seconds. For models with interior controls press and hold the Fridge and Power Cool buttons simultaneously for 3 seconds.

Old review:
Like many of you I have been looking at all the cheap aftermarket filters on Amazon for my Samsung fridge. All of them are NSF42 certified, but none have been NSF53 certified. This is the ONLY non OEM filter I've been able to find that is both NSF-42 and NSF-53 certified (the latter of which is the most important aspect of any filter). Furthermore, these cost half of what the Samsung OEM go for. NSF42 is unimportant with regards to filtration so don't be deceived by filters which only have this one certified.

All this said, please do not buy these here. You can get these at the Home Depot for 50 bucks for the value pack (2-pac). At 90 dollars you might as well just buy the OEM Samsung filters.

For those who are unaware, here is an excerpt on the nsf.org website about NSF53 certification.

"NSF/ANSI 53: Drinking Water Treatment Units - Health Effects

NSF/ANSI 53 establishes the minimum requirements for the certification of POU/POE filtration systems designed to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs) and MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water.

The scope of NSF/ANSI 53 includes material safety, structural integrity and health-related contaminant reduction performance claims. The most common technology addressed by this standard is carbon filtration."
