Water Filter for the Samsung RF28K9580SR (DA29-00020B)

RF28K9580SR specifics — where the filter actually lives

On the RF28K9580SR, the cartridge inside the fresh-food cavity, upper zone in most French-door builds — usually a kneeling-height or shoulder-height swap, not a teardown. It is a push-lock bay — the cartridge slides onto the header and latches — no tools, no housing removal, five minutes.

The small print owners learn the hard way: run the first gallon or two through a fresh cartridge before drinking — carbon fines are normal — and reset the indicator so the countdown matches reality. The badge reads RF28K9580SR, but the chassis reads RF: RF is Samsung’s French-door multi-door designation proper, and the service literature files every one of these under the same cartridge line. Finish letter sets like SR never alter the bay; the DA2900020B line fits the whole set.

RF vs RS — what the prefix tells you

Know your RF from your RS and the cartridge question halves: French-door multi-door on the RF side, side-by-side on the RS side — the parts catalog runs the same cartridge across both. call it a 28 cu ft box — which is why this cartridge works for a living rather than sitting decorative.

Swap it in 5 minutes

• Pull the old cartridge straight out of the header — expect a small spill, not a flood.
• Align the new cartridge with the keyed slot; it only goes in one orientation.
• Push the cartridge home until the retention latch clicks.
• Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.
