RS25J5008SP specifics — where the filter actually lives
The RS25J5008SP carries its water filter behind the lower fresh-food trim or base grille in most side-by-side layouts, a deliberate placement that keeps the swap away from the door seals and drawer rails. Mechanically the RS25J5008SP uses a push-in cartridge; the header accepts the cartridge one way; when it slides without force, it is aligned.
Field notes: a stubborn first twist when the old o-ring has set, and a change-filter light that will not clear itself until you hold the reset. Prefix literacy pays here: when Samsung stamps RS on the plate it is sorting the machine into the side-by-side class — same water path, same cartridge, different cabinet. Trailing letters like SP denote trim and finish: stainless, panel-ready, handle variants. The water path is identical across them.
RS vs RF — what the prefix tells you
The RS/RF pair divides this family by layout — RS answers to side-by-side; RF answers to French-door multi-door; the water-filter answer is shared. The two digits after the letters are the cabinet size: this is a 25 cu ft refrigerator, which sets how much dispenser work the cartridge does between changes.
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.

RS25J5008SP filter questions
How to reset the water filter indicator: Samsung RS25J5008SP?
Hold the filter-reset control a few seconds after the swap; the status light clears only with a seated cartridge, and the RS25J5008SP manual maps the control by panel type.
Can I run the Samsung RS25J5008SP with no cartridge installed?
Nothing to buy — the DA2900020B housing closes without a cartridge; water runs unfiltered until the next one goes in.
Are off-brand filters safe for a Samsung refrigerator?
Certified aftermarket cartridges are built to the same NSF test standards as the OEM part, and federal warranty law (Magnuson-Moss) protects your coverage when you use them.
Why is the OEM DA2900020B cartridge so much more expensive?
Part of the OEM price is the badge and the distribution chain. Certified alternatives meet the same test standards at a lower unit price, especially in multi-packs.
How often should I replace the filter in my RS25J5008SP?
Every six months or at the rated gallon capacity, whichever comes first — the DA2900020B class cartridges all share that service interval.
Do I need to turn off the water supply to change it?
No — the bay is designed for a live swap. Expect a small dribble, keep a towel in reach, and flush a couple of gallons through the new cartridge before the first glass.
