Refrigerator Water Filter Compatibility Finder

Enter your refrigerator model number below to find your exact, verified-compatible replacement filter.

By Neo Pecorro, Founder · Last updated August 24, 2026

Refrigerator water filters aren’t universal — the wrong cartridge can leak or simply not fit. This tool matches your exact refrigerator model or filter part number (like RPWFE, DA29-00020B, or LT1000P) to a verified-compatible replacement, so you can buy the right filter the first time.

We verify compatibility using manufacturer specs and cross-reference data, not just similar-looking part numbers. A filter that “should” fit isn’t the same as one that’s confirmed to fit, and the difference matters when you’re dealing with water flow, leaks, or a fridge that won’t reset the filter light.

Coverage includes GE, Samsung, LG, Whirlpool, Frigidaire, and Maytag, spanning hundreds of model numbers across each brand’s product lines.

Samsung owner? See our dedicated Samsung filter guide → for model-specific compatibility and replacement steps. Have a HAF-QIN or DA97-17376B filter instead? See our HAF-QIN compatibility guide →. LG, Whirlpool, or Frigidaire owner? See dedicated guides for LG LT1000P compatibility guide →, Whirlpool EDR1RXD1 compatibility guide →, and Frigidaire WF3CB →. GE owner? See our GE RPWFE compatibility guide →.

Have an older LG model? Check our LG LT700P compatibility page →

Every match on this page is cross-referenced against manufacturer specs and validated data — not just similar-looking part numbers. How we verify compatibility →

Every code in this tool’s database has cleared our verification process against manufacturer specs and cross-referenced sources — if your exact filter code or model number isn’t returning a match, it means we haven’t independently confirmed it yet, not that we’ve guessed and gotten it wrong.

How Do You Replace a Refrigerator Water Filter?

Most models follow the same basic process: shut off the water supply, twist or pull out the old filter, insert the new one, and run a few gallons through to flush carbon dust before drinking.

Exact steps vary by brand and model — see the dedicated guides above for Samsung, HAF-QIN, LG LT1000P, Whirlpool EDR1RXD1, and Frigidaire WF3CB for model-specific instructions. The general process across most brands:

1. Locate the filter housing — typically inside the refrigerator compartment (upper right) for French-door models, or behind the base grille for side-by-side models.
2. Remove the old filter: most twist a quarter-turn counterclockwise and pull straight out; push-button models release when pressed in.
3. Check the code printed on the old filter to confirm your replacement matches before installing.
4. Insert the new filter and turn clockwise until it locks, or push until it clicks into place.
5. Run water through the dispenser for 2 to 4 minutes to clear air and carbon fines before drinking.
6. Reset the filter indicator light using your model’s control panel — this step is often missed and is why the light sometimes stays on after a correct replacement.

Frequently Asked Questions

How often should I replace my refrigerator water filter?

Most manufacturers recommend every 6 months, or sooner if water flow noticeably slows or the indicator light signals a change. Some higher-capacity filters are rated for up to 300 gallons rather than a fixed time period.

Can I use a compatible filter instead of the genuine OEM filter?

Compatible third-party filters exist for most codes, but fit and filtration performance vary by manufacturer. Cheaper filters can fall short of OEM housing specifications, and a seal that doesn’t match the refrigerator’s filter head as closely can allow leaks or reduce contaminant reduction even when the filter clicks into place. Independent certification, specifically NSF/ANSI 42 and 53 marks on the packaging, is one of the more reliable signs a compatible filter has actually been tested for material safety and reduction claims rather than shape alone. We don’t physically test units ourselves, so we only confirm a match on this site after checking documented dimensions and fitment against OEM housing specifications, certification records, and published flow-rate data, rather than relying on a seller’s part-number claim by itself. A listing with no certification information at all is a reason for caution, not an assumption of compatibility.

What happens if I don’t replace my water filter on schedule?

Water flow slows, filtration effectiveness drops as the carbon media saturates, and in some models the ice maker can stop working entirely once the filter is far enough overdue. The carbon inside every filter has a finite capacity to bind chlorine, taste, and odor compounds; once it saturates, contaminants that the filter is rated to reduce begin passing through largely unfiltered even though water still flows. Many refrigerators track usage internally and will display a filter warning icon or error code well before flow stops completely, so a warning light is worth acting on immediately rather than waiting for a visible problem. A badly overdue filter can also allow bacteria to develop in media that is no longer actively filtering, which is why manufacturers generally recommend replacing on schedule rather than waiting for a full stoppage, the simplest way to avoid both a compromised ice maker and reduced water quality at the same time.

Why is my filter light still on after I replaced it?

Most models need a manual reset after a filter change — check your model’s reset procedure, usually a button hold or menu option on the display panel. This is the single most common reason people think they installed the wrong filter when they didn’t.

What if my exact filter code or model number isn’t listed here?

We do not publish a match until we have independently verified it. If a code does not appear, check the brand-specific guides linked from this page, or check back as coverage is actively expanding toward the full range of refrigerator models. The filter code itself is usually printed directly on the old filter cartridge or on a label inside the filter housing compartment, rather than on the refrigerator’s main rating plate, so start there before searching by model number. If you can only find the refrigerator’s model number and not a filter code, most manufacturer support sites will cross-reference the appliance model to its correct filter part number for free. In the meantime, most manufacturer support pages list the correct filter part number when you enter your refrigerator’s model number directly, which is a reliable fallback while our own verified catalog keeps expanding.

Refrigerator Water Filter Bypass Plugs

Running your fridge without a filter installed usually needs a bypass plug to keep the water line sealed. Which one you need depends on the housing type, not just the brand.
