Samsung DA29-00003G Water Filter (HAF-CU1): Complete Replacement Guide (2025)
Samsung DA29-00003G Water Filter (HAF-CU1): Complete Replacement Guide (2025)
The Samsung DA29-00003G — also known as the HAF-CU1 — is the twist-in water filter used in older Samsung French door refrigerators, primarily from around 2005–2015. It is frequently confused with the DA29-00020B (HAF-CIN), Samsung’s push-in filter used in newer models. The two are not interchangeable and have completely different mounting mechanisms.
Also known as: HAF-CU1, DA29-00003F (older revision) | Type: Twist-in, bottom of fridge interior | Location: Bottom of the refrigerator compartment — NOT upper right | Life: 6 months / 200 gallons | NSF: 42 and 53
The DA29-00003G is a twist-in filter at the bottom of the refrigerator interior. The DA29-00020B (HAF-CIN) is a push-in filter in the upper right. They are completely different physical designs that cannot be swapped. If your Samsung filter is in the upper right and pushes in — you need the DA29-00020B. If it twists in at the bottom of the fridge interior — you need the DA29-00003G. Read your installed filter label to confirm.

How to Install the Samsung DA29-00003G
Locate the Filter at the Bottom
Open the refrigerator. The DA29-00003G is located at the bottom of the refrigerator interior — look for a cylindrical filter in a housing at floor level inside the fridge compartment.
Turn Off Ice Maker
Switch off the ice maker to prevent water demand during the swap.
Remove the Old Filter — and Check the Housing Port
Grip the filter and rotate counterclockwise approximately a quarter-turn until it releases. Pull straight out. Have a towel ready.
Critical step unique to the DA29-00003G: Before inserting the new filter, shine a flashlight into the empty filter port. This older Samsung design occasionally leaves the old rubber O-ring stuck inside the housing seat rather than coming out with the filter. If the old O-ring remains inside and you install the new filter (which has its own O-ring), there are now two O-rings stacked in the seal groove — preventing correct compression and causing an immediate, continuous leak that no amount of tightening will fix.
Use a fingernail, a flat toothpick, or a plastic spudger to probe the inner rim of the housing port. If you feel or see a rubber ring that isn’t part of the housing itself — remove it before installing the new filter. The housing seat should be bare smooth plastic before the new filter goes in.
Prepare and Install
Remove the protective cap from the new DA29-00003G O-ring end. Align with the housing, push in, and rotate clockwise to a firm locked stop.
Flush and Reset
Run 2–3 gallons through the dispenser and discard. Reset the filter indicator: on most models, hold Ice Type + Child Lock simultaneously for 3 seconds. See: How to Reset Any Refrigerator Filter Light.
