Quick answer from a licensed plumber: Buy the genuine cartridge your fridge was built for, matched by the model on the old filter: an everydrop number for Whirlpool, Maytag, KitchenAid, Amana and JennAir; the GE XWFE, RPWFE or MWF for GE; the Samsung HAF-CIN/EXP; or the Frigidaire EPTWFU01. Each is listed by NSF or IAPMO R&T for lead and cyst reduction, among other claims.
Our pick for Whirlpool-family fridges: the everydrop Filter 1, NSF-listed to NSF/ANSI 42, 53 and 401. Check the everydrop Filter 1 on Amazon
A refrigerator water filter is the cartridge inside the fridge that cleans the water for the dispenser and the ice maker. The right one is the cartridge your fridge was built for, so this page is organized by fridge brand. For each brand we picked the genuine cartridge and checked the public certification listings, NSF, IAPMO R&T and WQA, for what it is certified to reduce. Every certification claim on this page comes from those listings, not from the box. If your fridge has no internal filter, see our inline refrigerator water filter picks instead.

Claims and capacities from the NSF and IAPMO R&T listings linked below, read on October 3, 2026; the full lists are longer, and they differ by model and version. Every linked listing was sold by Amazon.com and in stock on October 6, 2026. The everydrop Filter 2 is not linked: when we checked on October 6, 2026, its Amazon listing showed it as currently unavailable.
Start With the Model on Your Old Filter
Fridge filters are not universal. Each brand uses its own cartridge shape and lock, and many brands sell more than one. Pull the old cartridge and read the model on it, or look in the fridge manual. Then buy that model. The everydrop listings even say to match the number or letter and the color of the old filter.
What the Certification Listings Tell You
A filter is certified to a standard for specific claims, model by model. These are the standards in the listings on this page:
- NSF/ANSI 42 covers aesthetic claims such as chlorine, taste and odor, and particulates.
- NSF/ANSI 53 covers health-related claims such as lead, mercury, cyst and VOCs.
- NSF/ANSI 401 covers emerging compounds such as some medications, bisphenol A and, on some listings, microplastics.
- NSF P473 covers PFOA and PFOS.
Two certifiers show up for these genuine filters. NSF lists the everydrop and Samsung cartridges. IAPMO R&T lists the GE and Frigidaire cartridges; they are not on NSF’s site, which can make them look uncertified if you only check NSF. For more on reading these listings, see our NSF certified water filter guide.
LG: we could not confirm a listing
We searched NSF, IAPMO R&T and WQA on October 3, 2026 for LG’s LT1000P and LT700P cartridges and did not find them listed under LG. NSF’s LG Electronics listings cover the LT600P and LT800P instead. Because we could not confirm what the LT1000P or LT700P is certified to reduce, we do not pick one here. If you have an LG fridge, check the box for a certification mark and look up that exact model on the certifier’s site.
everydrop by Whirlpool Refrigerator Filters 1, 2, 3, 4 and A
Genuine Whirlpool-family cartridges, numbered or lettered and color coded · NSF-listed to NSF/ANSI 42, 53 and 401 · lead, cyst and asbestos reduction (53) and microplastics reduction (401) in every listed version of Filters 1, 2, 3, 4 and A · rated 200 gallons in most listed versions · replace every 6 months or 200 gallons, per the listings
If your fridge is a Whirlpool, Maytag, KitchenAid, Amana or JennAir, the genuine cartridge is an everydrop. The listings say to pick the package that matches the number or letter and the color of the filter you have now, so read the old cartridge before you order. Filters 1 and 3 push in; 2, 4 and A twist in, per their listings. The listings say to replace them every six months or every 200 gallons.
NSF lists the everydrop Filter 1 (EDR1RXD1), 2, 3, 4 and A under NSF/ANSI 42, 53 and 401. Every listed version of those five includes lead, cyst and asbestos reduction under Standard 53 and microplastics reduction under Standard 401; the full claim lists differ by version, so check the listing for the number on your box. For Filter 3, NSF lists PFOA and PFOS reduction on every listed version. Most listed versions are rated for 200 gallons; a few are listed at 100. The everydrop Filter 3 was also sold by Amazon.com and in stock when we checked.
Not linked: when we checked on October 6, 2026, the Amazon listing for the everydrop Filter 2 (EDR2RXD1) showed it as currently unavailable.
- NSF-listed to 42, 53 and 401
- Lead, cyst, asbestos and microplastics reduction in every listed version
- Number and color coded to match the old cartridge
- Six-month or 200-gallon change interval, per the listings
- Claim lists differ by version; read the listing for your number
- Only Filter 3 versions list PFOA and PFOS reduction

Verdict: Buy the everydrop number that matches your old cartridge; it is the NSF-listed genuine filter for Whirlpool-family fridges.
GE XWFE, RPWFE and MWF Genuine Refrigerator Water Filters
Genuine GE Appliances cartridges · IAPMO R&T-listed to NSF/ANSI 42, 53, 401 and NSF P473 · XWFE and RPWFE: lead, mercury, cyst, asbestos, VOC and toxaphene reduction (53), chloramine and chlorine (42) · MWF: adds PFOA/PFOS under Standard 53 · all three listed for PFOA/PFOS under P473 · rated 170 gallons · replace every 6 months, per the listings
We found GE’s cartridges in IAPMO R&T’s directory, not in NSF’s listings. IAPMO lists the XWFE, RPWFE and MWF to NSF/ANSI 42, 53 and 401, and to NSF P473 for PFOA and PFOS, each rated at 170 gallons and 0.5 gpm. Under Standard 53 the XWFE and RPWFE carry lead, mercury, cyst, asbestos, VOC and toxaphene reduction. The MWF’s Standard 53 row adds PFOA/PFOS. Under Standard 42, IAPMO lists chloramine reduction for the XWFE and RPWFE, which matters if your city treats its water with chloramine.
They are three different cartridges. The Amazon listings say the XWFE fits select GE French door, side-by-side and built-in fridges, the RPWFE select French door fridges, and the MWF select French door, side-by-side and built-in fridges, across the GE, GE Profile, Café and Monogram brands. Match the model printed on your old cartridge. The listings say installation needs no tools or water shutoff and to replace the filter every 6 months.
- Listed to four standards, including NSF P473 for PFOA/PFOS
- Lead, mercury, cyst, asbestos and VOC reduction on all three
- Chloramine reduction listed for XWFE and RPWFE
- No tools or shutoff to change, per the listings
- Rated 170 gallons, below Samsung’s 300 and most everydrop versions’ 200
- Three different cartridges; match the model on your old one
- Certified through IAPMO, so you will not find them on NSF’s site
Verdict: Buy the GE cartridge whose model matches your old one; all three are listed to four standards, including NSF P473 for PFOA and PFOS.
Samsung HAF-CIN/EXP Genuine Refrigerator Water Filter (DA29-00020B)
Genuine Samsung cartridge · NSF-listed to NSF/ANSI 42, 53 and 401 under Samsung Electronics · lead, mercury, cyst, asbestos, benzene and turbidity among its Standard 53 claims · 14 to 16 Standard 401 claims by NSF row, including atenolol, bisphenol A and naproxen · rated 300 gallons · authentication tag · replace every 6 months, per the listing
For a Samsung French door, side-by-side or Bespoke fridge that uses the HAF-CIN/EXP, NSF lists the genuine cartridge under Samsung Electronics with replacement element DA29-00020B. Its Standard 53 row includes lead, mercury, cyst, asbestos, benzene, atrazine, lindane, toxaphene and turbidity reduction, and its Standard 401 row lists 14 emerging compounds such as atenolol, bisphenol A and naproxen. A second NSF row lists a Samsung-brand HAF-CIN/EXP under Handok Clean Tech, and that row adds ibuprofen and microplastics. The rated capacity is 300 gallons, the highest on this page.
Samsung’s listing describes an authentication tag: you hold it over the supplied magnet, and green stripes appear on a genuine Samsung filter. That is Samsung’s claim, but it is a useful check when look-alike cartridges share the same part number in their titles. The listing says to replace the filter every 6 months.
- NSF-listed under Samsung Electronics to 42, 53 and 401
- Lead, mercury, cyst and asbestos reduction listed
- Rated 300 gallons, the highest here
- Authentication tag in the box, per Samsung
- No PFOA/PFOS claim in its NSF rows; microplastics on one of its two
- Fits only fridges that take the HAF-CIN/EXP
Verdict: The genuine filter for Samsung fridges that take the HAF-CIN/EXP, with NSF listings under Samsung’s own name.
Frigidaire PureSource Ultra II EPTWFU01 Refrigerator Water Filter
Genuine Frigidaire cartridge · IAPMO R&T-listed to NSF/ANSI 42, 53 and 401 under Electrolux Home Products · lead, mercury, cyst, asbestos, VOC and PFOA/PFOS reduction (53) · microplastics reduction (401) · rated 125 gallons at 0.65 gpm · push-and-twist install
Frigidaire’s PureSource Ultra II is listed by IAPMO R&T under Electrolux Home Products. Its Standard 53 row includes asbestos, mercury, lead, VOC, benzene, cyst and PFOA/PFOS reduction, and its Standard 401 row adds microplastics, bisphenol A and several medications. IAPMO rates it at 125 gallons, below the GE, Samsung and most everydrop listings, so a busy ice maker uses it up sooner.
The listing describes the change: turn the old filter 90 degrees counterclockwise and pull it out, then slide the new one in with the grip horizontal, push firmly and turn it 90 degrees to the right until it clicks. It also says the reminder light does not reset on its own; on most models, hold the Water Filter button on the dispenser for 3 seconds until the display turns from red to green. The Amazon listing mentions nitrates, but we did not find a nitrate claim in the IAPMO listing, so we do not repeat it.
- Listed to 42, 53 and 401 through IAPMO
- Lead, cyst, PFOA/PFOS and microplastics reduction listed
- Push-and-twist change, per the listing
- Reminder reset steps in the listing
- Rated 125 gallons, below the GE, Samsung and most everydrop listings
- Reminder light must be reset by hand
- Listing claims a nitrate reduction we could not find in the IAPMO listing
Verdict: The genuine filter for Frigidaire fridges that use the PureSource Ultra II, with lead and PFOA/PFOS claims listed.

Before You Buy
- Read the old cartridge. Buy the exact model it shows.
- Look up that model. NSF for everydrop and Samsung, IAPMO R&T for GE and Frigidaire.
- Match the claims to your water. If your water report shows lead, PFOA or PFOS, buy a model whose listing carries that claim.
- Plan the change interval. Six months on the everydrop, GE and Samsung listings, or sooner if you reach the rated gallons.
- Buy from a seller you trust. Every link here was sold by Amazon.com when we checked.
Changing a Refrigerator Water Filter
The makers’ listings call the change simple. The everydrop listings describe push-in and twist-in styles, the GE listings say no tools or water shutoff are needed, and the Frigidaire listing gives a push-and-twist sequence and a 3-second button hold to reset the reminder light.
Plumber’s note: keep a towel under the filter housing, since a little water comes out with the old cartridge. After a new cartridge goes in, flush water through the dispenser as the instructions with the filter say before you drink it; that pushes out trapped air and loose carbon. If the dispenser still spits or runs slow, check that the cartridge is fully seated and locked. If the problem is the water line feeding the fridge, see our ice maker water line kits.
FAQ
How do I find the right refrigerator water filter?
Pull the old cartridge and read the model on it, or check your fridge manual. The genuine filters on this page are matched by that model: everydrop uses a number or letter and a color, GE uses XWFE, RPWFE or MWF, Samsung uses HAF-CIN/EXP and Frigidaire uses EPTWFU01. Then look that exact model up in the NSF, IAPMO R&T or WQA listings.
How often should I change my refrigerator water filter?
The everydrop listings say every six months or every 200 gallons, and the GE and Samsung listings say every 6 months. The certification listings give a rated capacity for each model: 200 gallons for most everydrop versions, 170 for GE, 300 for Samsung and 125 for Frigidaire. A household that drinks and makes ice from the fridge can reach the capacity before the date.
Are off-brand refrigerator filters certified?
Some are, but certification is model by model. The same NSF and IAPMO listings that cover the genuine filters also list some aftermarket cartridges, with their own claim lists. For example, NSF lists an aftermarket RPWFE replacement with cyst, lead, benzene, carbofuran and endrin reduction under Standard 53, while IAPMO lists mercury, lead, cyst, asbestos, VOC and toxaphene reduction for the genuine RPWFE. Check the listing for the exact model on the box.
Do refrigerator filters remove PFAS?
Some are listed for two PFAS compounds, PFOA and PFOS. IAPMO lists the GE XWFE, RPWFE and MWF to NSF P473 for PFOA and PFOS, and lists PFOA/PFOS reduction for the Frigidaire EPTWFU01 under Standard 53. NSF lists PFOA and PFOS reduction for every listed version of the everydrop Filter 3 (EDR3RXD1). We did not find a PFOA or PFOS claim in the Samsung HAF-CIN/EXP NSF rows, and none of the listings we read uses the wider term PFAS.
What if my refrigerator has no water filter?
Add an inline filter on the water line that feeds the fridge. Our inline refrigerator water filter guide covers those, and our ice maker water line kits page covers the supply line itself.
