Which Water Filter Fits Your Refrigerator?

Buying the wrong refrigerator water filter is the most common and avoidable mistake – the fix is to match the right part to your exact refrigerator. This guide shows how to find your fridge’s model number, how to identify the correct filter part number, where the filter is located, and the standard naming conventions by brand. Safe Appliances supplies genuine OEM filters wholesale and will cross-reference your model list for you.

Step 1: Find your refrigerator model number

The model number is printed on a manufacturer’s sticker on the appliance itself – do not use the number in your user manual, as manuals often cover several similar models. Check these common spots:

• Ceiling of the fresh-food compartment – near the front or center.
• Inside side walls – on the left or right liner wall.
• Behind the crisper drawer – pull out the bottom produce drawers; the sticker is often on the wall behind them.
• Door jamb or frame – along the edge of the door frame or the side edge of the door.
• Kick plate – at the very bottom front, behind the base grille.

Step 2: Find the correct filter part number

With the refrigerator model number in hand, identify the matching filter one of three ways:

• Read the current filter label – if a cartridge is installed, remove it; the part number (a mix of letters and numbers, such as EDR1RXD1 or DA29-00003G) is printed on the label.
• Search by model number – enter your refrigerator model number followed by “water filter” to find the compatible cartridge.
• Use the brand’s naming convention – most brands use standard filter families (see the table below).

Standard filter numbering by brand

Where is the filter located?

Depending on brand and style (French-door, side-by-side or bottom-freezer), the cartridge is usually in one of three places:

How to avoid buying the wrong filter

• Always match by the refrigerator model number or the exact filter part number – not by how the cartridge looks.
• Confirm the generation: some brands changed housings over time (for example Samsung’s HAF-CIN vs HAF-QIN, or Frigidaire’s PureSource Ultra vs Ultra II).
• Choose genuine OEM cartridges that carry the NSF/ANSI certifications printed on the box.
• Buy a spare so you stay on the 6-month replacement schedule.
