Water Filter for the Samsung RS2621SH (DA29-00003G)

RS2621SH specifics — where the filter actually lives

The filter bay on the RS2621SH bottom of the fresh-food column or at the grille line in most side-by-side builds, a deliberate placement that keeps the swap away from the door seals and drawer rails. Mechanically the RS2621SH uses a push-in cartridge; seat the cartridge square to the header until it clicks, and the retention clips do the rest.

Before you click buy, two things: a stiff first removal on builds that sat on the same cartridge for years, and an indicator light that wants a manual reset after a non-OEM cartridge is seated. The RS in RS2621SH is doing real work: RS is Samsung’s own coding for side-by-side machines, and in that format the water path is long enough that a neglected cartridge shows up as flow drop before it shows up as taste. Finish codes such as SH change the look, not the plumbing — order the cartridge by model, ignore the finish letter.

RS vs RF — what the prefix tells you

The RS prefix sits next to RF in the catalog and the split is cabinet mission: RS means side-by-side, RF means French-door multi-door. For filter shopping the distinction matters less than you would think — same line, different cabinet. call it a 26 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.
