Refrigerator Water Filter Replacement (2026): Find the Right One
Fridge water filters cost $15–$60 and should be replaced every 6 months. Find the right filter by brand — GE, Samsung, LG, Frigidaire — and OEM vs aftermarket.
Typical cost ranges
| Item | Low | High | Notes |
|---|---|---|---|
| Aftermarket certified filter (single) | $15 | $30 | Look for NSF/ANSI 42 and 53 certification on the label. |
| OEM brand filter (single) | $35 | $60 | Sold by the fridge manufacturer. Warranty-safe, pricier. |
| Certified filter multipack (3-pack) | $40 | $80 | Brings the per-filter cost down to $13–$27. Best value. |
| Bulk / generic uncertified filter | $8 | $18 | No NSF certification. Can leak or fit badly. Not recommended. |
| Whole-year supply (2 filters) | $30 | $110 | Two filters covers about 12 months of typical use. |
| Inline / twist-in type (varies by fridge) | $20 | $70 | Some fridges use a twist-in cartridge, others an inline one. |
| Fridge filter housing repair (if leaking) | $80 | $300 | When the housing rather than the filter is the problem. |
| Fridge repair call-out (for comparison) | $100 | $250 | See our water filter system guide for whole-home options. |
Ranges are typical U.S. market estimates for 2026 and vary by region, home, and contractor. Always confirm a written quote before work begins.
A refrigerator water filter costs $15–$30 for a certified aftermarket filter and $35–$60 for the OEM version, and it should be replaced roughly every six months. The filtration is the same if the aftermarket filter carries NSF/ANSI 42 and 53 certification. What you are paying the extra for with OEM is brand certainty and no argument about warranty.
The step people get wrong is the part number. A wrong filter will not seat properly, and an unseated filter can leak into the fridge. Read the number off the old filter before you order anything.

How to find your filter
Three routes, in order of reliability:
1. Read the old filter. The part number is printed on the label. This is the only method that is guaranteed to be correct, so do it before you throw the old one away.
2. Look up your fridge model number. It is on a plate inside the fridge (often on the left wall) or behind the crisper drawers. Search the model number plus “water filter”.
3. Use the brand’s filter finder. Every major brand has one. Useful, but it occasionally suggests the wrong generation for older models.
Do not assume that a similar fridge uses the same filter. GE and Samsung both change filter designs between generations, and the models look nearly identical from the outside. A filter that will not click into place is the wrong filter, not a broken one.
Brand by brand
| Brand | Typical filter families | Filter cost | Notes |
|---|---|---|---|
| GE | MWF, XWFE, RPWFE | $25–$60 | The RPWFE has an RFID chip that blocks some generics |
| Samsung | HAF-CIN, HAF-QIN | $20–$50 | Very widely copied; certified generics are plentiful |
| LG | LT500P, LT700P, LT1000P | $18–$45 | Long replacement intervals; often out of stock |
| Frigidaire | PureSource, UltraWF | $20–$50 | Two generations share a name — check the number |
| Whirlpool | EveryDrop (EDR series) | $25–$50 | EveryDrop is the OEM brand for several makers |
| Brita | Pitcher and faucet filters | $5–$15 | Not a fridge filter, but commonly searched together |
The GE RPWFE is the one to be careful with. It contains an RFID chip, and non-chipped generics will cause the fridge to keep reporting a filter fault. For that model, either buy a genuine RPWFE or a generic that explicitly states it is chip-equipped.
OEM vs aftermarket: the actual difference
| OEM | Certified aftermarket | |
|---|---|---|
| Filtration | NSF 42 / 53 | NSF 42 / 53 (same standards) |
| Price | $35–$60 | $15–$30 |
| Fit | Guaranteed | Usually identical — many are made in the same plants |
| Warranty friction | None | Occasional argument |
| Availability | Sometimes backordered | Widely stocked |
The honest position: certified aftermarket filters are the same product for less money. The two things to verify are the NSF/ANSI certification mark and the part number match. Skip the uncertified $8 generics, where the risk is a poor seal leaking into the fridge rather than poor filtration.
How often to replace it
| Signal | Action |
|---|---|
| Six months have passed | Replace on schedule |
| Filter indicator light on | Replace |
| Flow has noticeably slowed | Replace now |
| Water tastes or smells off | Replace now, then test if it recurs |
| Party or heavy use period | Shorten the interval |
The six-month figure assumes typical household use, roughly 300 gallons. Heavy use, or water with a lot of sediment, shortens it. A filter left in for two years is not just ineffective, it can become a bacterial growth point, which is worse than no filter at all.
Do you even need the fridge filter?
If you already have a whole-house filtration system, running the fridge without a filter is entirely reasonable. Most fridges ship with a bypass plug, and you can usually disable the indicator light in the settings.
The trade-off: the fridge filter is usually a carbon block, which is good at chlorine and taste. A whole-house sediment and carbon setup covers that upstream, so the fridge filter is redundant. If you have no whole-house system, keep the fridge filter.
Installation, in five steps
- Shut off the water supply if you can reach the valve, and remove the old filter.
- Note the orientation — twist-in cartridges only seat one way.
- Fit the new filter and turn until it clicks or stops firmly. Do not force it.
- Flush 2–3 gallons through the dispenser. The first water will be cloudy and may contain harmless carbon fines. This is normal.
- Reset the indicator — usually a long press of the filter button, or in the app on newer models.
If the dispenser sputters for more than a few seconds, the filter is not seated. Remove and refit it.
Common mistakes
- Ordering before reading the part number. The single most common error.
- Buying the cheapest generic. Fit and seal quality are where they fail.
- Forgetting the flush. The first glass after a change looks alarming and is harmless.
- Never resetting the indicator. Then you cannot trust the light.
- Leaving a filter in for years. Worse than running unfiltered.
- Assuming a similar model uses the same filter. Check the number, every time.
Bottom line
A fridge water filter costs $15–$30 certified aftermarket or $35–$60 OEM, and needs changing about every six months. Buy a three-pack if you can, verify the NSF certification, and always match the part number from the old filter.
If you already filter your whole house, the fridge filter is optional. If you do not, see our whole house water filter cost guide to compare the two approaches.

Frequently asked questions
How often should I replace my refrigerator water filter?
Every six months for most households, or sooner if you use a lot of water. Replace it immediately if the flow slows noticeably, the water starts tasting or smelling off, or the fridge's filter indicator light comes on. A filter left in place for years stops filtering and can harbour bacteria.
How much does a refrigerator water filter cost?
Certified aftermarket filters cost $15–$30 each, OEM filters from the fridge manufacturer $35–$60. A three-pack of certified filters usually runs $40–$80, which brings the cost per filter down to about $13–$27 for the same filtration. Buying in a multipack is the easiest saving in this category.
Are aftermarket fridge filters as good as OEM?
If they carry NSF/ANSI 42 and 53 certification, yes: they are tested to the same standards and filter the same contaminants. The risks with cheap generics are fit and build quality rather than filtration, since an ill-fitting filter can leak and damage the fridge. Check for the NSF mark and a part number matching your original.
Does using an aftermarket filter void my fridge warranty?
In the US, the Magnuson-Moss Warranty Act generally prevents a manufacturer from voiding a warranty simply because you used a third-party part, provided the part is of comparable quality and did not cause the damage. In practice, though, some manufacturers dispute this. If the fridge is still under a full warranty and you want zero friction, an OEM filter removes the argument.
How do I find the right filter for my fridge?
Open the old filter and read the part number printed on the label, or find the model number on a plate inside the fridge and look up its filter. The part number is the reliable method. Fridge model numbers are often similar across years, but their filters are not interchangeable, and a wrong filter will not seat correctly.
What if my fridge filter is not a twist-in type?
Fridges use three common designs: twist-in cartridges inside the fridge, push-in cartridges, and inline filters mounted on the water line behind or below the unit. Twist-in and push-in are user-serviceable. An inline filter behind the fridge may require pulling the unit out, and if the shut-off valve is seized, that is a plumber's job.
Can I use my fridge without a filter?
Yes. Most fridges have a bypass plug that lets you run without a filter, and some let you disable the indicator. The water will be unfiltered, so it will carry whatever is in your supply, and the ice maker will use it too. It is a reasonable choice if you already have a whole-house filtration system.
Why is my filtered water still tasting bad?
Three usual causes: the filter is overdue and needs changing, the filter is not seated properly so water is bypassing it, or you need a carbon filter for taste rather than a sediment-only one. If a fresh, correctly seated filter does not fix it, test the incoming water, because the problem may be upstream of the fridge entirely.
