If you are shopping for discount refrigerator water filters, start from the part number on your old cartridge, not the fridge brand. Samsung’s DA29 family has several numbers that look almost identical — 00020B, 00003G, 00003F, 10105J — and ordering the wrong one means a filter that will not fit. This guide covers how to confirm your number, what each one costs genuine, how to swap it, how to reset the light, and what to do when something goes wrong — everything in one place.
Which DA29 number is yours
Do not order by “Samsung filter” alone. Find the number printed on your old cartridge or on the filter housing label inside the fridge. The numbers that matter:
- DA29-00020B (HAF-CIN/EXP) — the genuine Samsung filter sold under this number, stocked here from $36.97.
- DA29-00003G (also sold as Aqua-Pure Plus) — a different genuine Samsung filter, stocked here from $38.99.
- DA29-00003F and DA29-10105J — other DA29 numbers, also stocked here. Their prices are on their product pages.
A number that looks close is not the same filter. If your cartridge says 00020B, order 00020B. If it says 00003G, order 00003G. Matching the exact number is the whole game — it is also how you avoid the most common post-change problems below.
What a genuine DA29 costs — an honest comparison
Genuine Samsung DA29 filters here start at $36.97 for the 00020B and $38.99 for the 00003G, with multi-packs bringing the per-filter price down (00020B packs to $110.46, 00003G packs to $145.99 — see the product pages for the current pack prices). Against the rival store’s genuine DA29 at $40.94, the single 00020B is already cheaper before shipping — and shipping is free US here, while the rival’s free shipping starts only over $75, so a single filter from them costs you shipping on top. A compatible DA29 at a lower sticker price is not the same thing: it is a copy, not the genuine Samsung cartridge, and fit and seal are where copies fail.
Need the filter itself? Shop the genuine Samsung DA29-00020B from $36.97, or the genuine Samsung DA29-00003G from $38.99 — genuine OEM, free US shipping, 30-day free returns.
How to swap a DA29 filter
- Turn off the water supply if your model asks for it, then open the filter housing (usually inside the fridge, upper right, or in the base grille depending on model).
- Turn the old cartridge counter-clockwise and pull it out.
- Push the new DA29 cartridge in and turn it clockwise until it locks — a cartridge a quarter-turn short is the most common cause of slow flow after a change.
- Flush several gallons through the dispenser to clear carbon fines, then reset the filter indicator as below.
If flow is slow or the water looks cloudy after the swap, check seating first before assuming the cartridge is faulty — it almost never is.
How to reset the Samsung filter light
Fitting a new filter does not clear the light on its own — the indicator is a reminder clock, not a sensor. Fit and flush first, then reset through your model’s filter-reset control (on most Samsung models this is a 3-second hold on the reset control — the exact control varies by model, so use your manual). The full model-by-model walkthrough is in our Samsung refrigerator water filter reset guide.
If something is wrong after the change
- Slow flow: the cartridge is usually not fully seated and locked. Push and turn until it locks, then flush again.
- Cloudy water: flush several gallons. Carbon fines clear with flushing and are not a fault.
- Light still on: the reset step above was missed or did not take. Re-seat the cartridge, then reset again.
- Leak at the housing: remove the cartridge, check the seal area, and refit until it locks. A poor seal also bypasses filtration, so do not ignore it.

FAQ
Is DA29-00020B the same as DA29-00003G?
No. They are different genuine Samsung filters for different fitments. Order the exact number printed on your old cartridge.
How often should I replace a DA29 filter?
About every 6 months, or sooner if flow slows, taste changes, or the indicator light comes on.
Do I need tools to replace it?
No. It is a twist-in cartridge. Turn out the old one, turn in the new one until it locks, flush, and reset the indicator.
My new filter is in but the water is slow. What is wrong?
First re-check that the cartridge is fully seated and locked, then flush again. A quarter-turn short is the most common cause of slow flow after a change.
Is the genuine Samsung filter worth it over a compatible?
The genuine cartridge guarantees the exact fit and seal for your model. A compatible that does not seal properly can leak, bypass filtration, or restrict flow — and at $36.97 genuine here, the gap to a copy is small.
