How to Find Your Refrigerator Water Filter Model Number (Every Brand, 3 Methods)
How to Find Your Refrigerator Water Filter Model Number (Every Brand, 3 Methods)
Wrong filter orders are the most common frustration in the refrigerator filter category. Someone searches for their brand, orders what looks right, and receives a filter that either won’t seat or won’t seal. The fix is always the same: identify the exact filter model number before ordering — not the fridge brand, not the fridge model, but the specific filter part number.
This guide gives you three methods to find your filter number in under 60 seconds, for every major refrigerator brand.
Open your fridge and read the label on your currently installed filter. The filter part number (e.g. LT1000P, DA29-00020B, EDR3RXD1) is printed directly on it. This is more reliable than looking up by fridge model number, because the same refrigerator series sometimes shipped with different filter generations at different production dates.
Method 1 — Read the Installed Filter Label (Best Method)
This is the single most reliable filter identification method. Here’s how to do it for each brand:
LG Refrigerators
Open the fridge and look in the upper right interior corner. The LG filter is a cylindrical cartridge protruding from a round housing. Pull it out slightly if needed to read the label clearly.
📍 Upper right interiorSamsung Refrigerators
Samsung filters are in one of two locations depending on your model. Older French door and side-by-side models (RF28, RF26, RS25): look in the upper right interior. Newer 4-Door Flex and Bespoke models: look at the bottom-left front grille at floor level.
📍 Upper right interior OR bottom-left grilleWhirlpool, Maytag, KitchenAid, Kenmore (106.), Amana
These brands use the EveryDrop filter platform. Open the fridge and look in the upper interior — the filter is a twist-in cartridge. The EveryDrop number (EDR1RXD1, EDR3RXD1, etc.) or older W-number (W10295370A) will be on the label.
📍 Upper interior of fridge compartmentGE, GE Profile, GE Café
GE filters are located in the upper right interior of the refrigerator compartment on most models. Push the release button and the filter ejects partially. Read the label on the filter body.
📍 Upper right interior — push-button releaseFrigidaire and Electrolux
Frigidaire filters are in the upper right interior of the fridge compartment. Press the eject button and pull the filter out to read the label.
📍 Upper right interior — push-button ejectKenmore Refrigerators
For Kenmore, first identify the manufacturer using your model number prefix (106. = Whirlpool, 795. = LG, 253. = Frigidaire), then use the method for that manufacturer above. Full guide: Best Kenmore Refrigerator Water Filters.
📍 Location depends on manufacturer
Method 2 — Use Your Refrigerator Model Number
If the installed filter label is unreadable, damaged, or the filter has already been removed, use your refrigerator’s model number to identify the correct filter.
Where to find your refrigerator model number:
- Inside the door frame: Open the left door and look along the left or top interior edge — most brands place a sticker here
- Behind the crisper drawers: Remove the crisper drawers and look on the back wall of the lower fridge compartment
- On the back of the refrigerator: A sticker on the exterior rear panel — less accessible but always present
- Inside the freezer door frame: Some brands (particularly LG) place the model sticker here
Once you have your refrigerator model number, enter it at our Filter Compatibility Checker for an instant guaranteed filter match. Our database covers 2,000+ refrigerator models across all major brands.
Method 3 — Check Your Refrigerator Manual or Manufacturer Website
Your refrigerator’s user manual (physical copy or PDF via the manufacturer’s support site) will list the correct filter part number in the Water Filter or Maintenance section. This is particularly useful for:
- Very new refrigerators where the installed filter may not yet have a readable label
- Refrigerators that have had the filter replaced by a previous owner using a different brand
- Confirming the correct filter when the installed label and the model-number lookup give conflicting results
The brand-by-brand location instructions above apply to standard French door, side-by-side, and bottom-freezer refrigerators from the major brands covered (LG, Samsung, Whirlpool, GE, Frigidaire, Kenmore). They do not reliably apply to built-in, column, or luxury refrigerators from brands such as Sub-Zero, Thermador, Miele, Viking, Wolf, Bosch, or Fisher & Paykel. These brands often use proprietary filter systems in non-standard locations — inside a dedicated filter housing in the ceiling of the fresh food compartment, in the door, or in an external housing on the supply line. If you own a built-in or premium refrigerator, consult the specific brand’s owner manual or support site for the exact filter location and part number.

Common Filter Identification Mistakes to Avoid
| Common Mistake | Why It Causes Wrong Orders | The Right Approach |
|---|---|---|
| Ordering by fridge brand alone (“Samsung filter”) | Samsung uses 3+ different filters across their lineup — brand name is not a filter specification | Read the installed filter label or enter fridge model number |
| Assuming same filter fits same model series | LG’s LRMVS series shipped with LT700P pre-2018 and LT1000P post-2018 | Always verify from the filter label, not the fridge name |
| Ordering Whirlpool Filter 3 when fridge needs Filter 1 | Filter 1 and Filter 3 look identical but have different thread patterns | Read the EDR number (EDR1RXD1 vs EDR3RXD1) from the installed filter |
| Using fridge model number from memory | Misremembered model numbers are a frequent cause of wrong filter orders | Photograph the sticker inside the door frame for a permanent record |
Pro tip: Photograph your filter label right now
Take a photo of your installed filter’s label and save it in your phone’s photos. Next time you need a replacement, you’ll have the exact part number available without opening the fridge.
