Product review (5 stars): This was the best price for the samsung replacement!
I needed  to find a replacement for my water filter Model# HAF-Cin/EXP  replacement cartridge was DA29-00020A, they do not make that filter anymore. I called Sears and asked about the DA29-00020B and they said it was fine to replace with that filter. Easy to install just twist it on. Then get a bowl and empty a gallon of water out which will get the water moving correctly. Yes these cartridges are expensive but I found Amazon to have the best price. Very happy I found it.
