Product review (2 stars): e-mail the company was useless, they ask for the model number
Replacement cartridges for Samsung DA29-00020B OR HAF-CIN/EXP.  the original Samsung filter spec are ANSI 42 and 53,  30-125psi, this replacement advertised as ANSI 42/53, but only 42,. NOT 53. The pressure is 30-120psi.
I had to adjust the pressure, as the water are flowing much faster in comparison to the Samsung one.
The hole in the front/center of the unit is big ~6mm in comparison to the 2mm in the Samsung filter.
The first few gallons came with white partials.
I chose this pack because it is advertised as ANSI 42/53, e-mail the company was useless, they ask for the model number, the invoice number etc, never responded for the false advertisement.
The test is OK not as the original one, so far it does not leak.
