DA29-00003G (Samsung HAF-CU1) Wholesale & Cross-Reference

The Samsung DA29-00003G – also sold as the HAF-CU1 – is the genuine OEM refrigerator water filter for a wide range of Samsung French-door and side-by-side models, and Safe Appliances supplies it wholesale at dealer pricing, in bulk, with OEM quality and a low return rate. This guide covers what the DA29-00003G is, full specifications, what it reduces, its OEM cross-reference numbers and compatible Samsung models, how to install and maintain it, and why genuine OEM matters for resellers.

DA29-00003G and HAF-CU1 – the same filter

The DA29-00003G and HAF-CU1 are the same genuine Samsung filter. Over time Samsung revised the part number and the cartridge housing – moving from an earlier two-rib lock to a tighter-fitting three-rib lock – but the filters remain fully interchangeable in the same refrigerator models. If your old cartridge was labelled DA29-00003A, -00003B, -00003D or -00003F, the DA29-00003G is the current replacement.

Full specifications

What the DA29-00003G reduces

The genuine cartridge is certified to recognized NSF/ANSI standards:

• NSF/ANSI 42 – aesthetic effects: chlorine taste and odor, and particulates.
• NSF/ANSI 53 – health effects: contaminants such as lead, mercury, asbestos and select pesticides.

Its high-grade carbon block delivers cleaner, better-tasting water and ice without stripping out beneficial minerals.

How to install or replace the DA29-00003G

1. Locate the cartridge (most Samsung models house it inside the fresh-food compartment, upper-right corner; some sit behind the base grille).
2. Turn the old cartridge about a quarter turn counter-clockwise and pull it straight out.
3. Insert the new DA29-00003G and twist clockwise until it locks – no tools needed.
4. Run about 2-3 gallons (roughly 3-4 minutes) through the dispenser to flush carbon fines and clear trapped air.
5. Reset the filter indicator (on most models, press and hold the filter or reset button for about 3 seconds).

When to replace and maintenance

Replace about every 6 months or 300 gallons, whichever comes first. Replace sooner if you notice:

• Reduced water or ice dispenser flow;
• A returning chlorine taste or odor;
• The filter-status indicator turning red;
• Cloudy or off-tasting water.

An exhausted carbon block stops reducing contaminants effectively and can restrict flow. The regular 6-month cycle also makes the DA29-00003G a strong repeat-order item for resellers.

Why genuine OEM

Genuine OEM DA29-00003G cartridges guarantee exact fit – including the current three-rib lock housing – and the stated NSF/ANSI 42 and 53 performance. For retailers and repair companies, that keeps returns and callbacks low, which protects margin on volume and builds repeat trust with end customers.

Troubleshooting

• Filter will not lock or sticks out: confirm you have the current DA29-00003G (three-rib lock), align the tab and twist firmly until it seats.
• No or slow water after replacement: make sure the cartridge is fully seated and locked, then flush trapped air by running the dispenser.
• Sputtering or air in the line: normal for the first minute or two after a change – keep flushing until the stream is steady.
• Cloudy water: usually trapped air, which is harmless and clears after flushing.
• Leaking: re-seat the cartridge, confirm it is the correct model, and check the seal.
