A:AnswerHi, yes you would have to turn off the water supply when changing the water filter. Here is a link that may be of help. https://bit.ly/2PWPwzM. HAF-CIN/EXP is the water filter model number. Thank you for choosing Samsung. ^SuSu
A:AnswerHello! To confirm compatibility, I would recommend checking out this link (https://bit.ly/2AOWwtX). At the bottom of the page, it lists all the refrigerators that this water filter will work with. ^Jecca
A:AnswerGood question patterson. I just double-checked on our parts website (https://bit.ly/2AOWwtX) and this filter will fit the refrigerator model RF28HFEDBSR. ^Jecca
A:AnswerThe filter wants to be replaced about every six months.
It pays to buy the best priced multi-pack on a subscription basis (and skip a "next shipment" whenever necessary)
They don't go stale when kept dry and sealed.
A:AnswerHi There,
We recommend using only Samsung Water Filters. There are 3 different Samsung water filters, and the HAF-CIN is the compatible one with your fridge.
