Product review (5 stars): 9/12/17 two for $17, 3/16/18 two for $26 - a $9 INCREASE in 6 months!
A suitable replacement for the OEM Samsung filter which is even more expensive.

Don't forget to take the protective plastic cap off BEFORE attempting to install.  Note, water may leak from dispenser for a bit till you have run air/water out of the system.
