everydrop Water Filter Numbers Explained: Which One Fits (2026)

We may earn commission from links on this page. Lead-form submissions are forwarded to local inspector partners. How we research and review.

An everydrop water filter is Whirlpool’s genuine refrigerator cartridge, sold for Whirlpool, Maytag, KitchenAid, Amana and JennAir fridges. The confusing part is the numbering. Instead of one universal cartridge, everydrop sells Filter 1, Filter 2, Filter 3, Filter 4, Filter 5 and a newer Filter A, each with its own color band and its own part number, and each fits a different housing. The number on the box is the whole decision. This guide decodes what each number means, which older part numbers it replaces, how to tell which one your fridge takes, and when a third-party compatible is a sensible substitute.

How we compared: we compared 12 current Amazon listings, seven genuine everydrop filters and five third-party compatibles, on what each listing actually states: filter number, color code, install style, NSF standards named, contaminant claims, part numbers replaced and stated service life. We did not lab-test any of these filters or install them hands-on. Prices and availability change often, so check the current listing before buying.

Which filter fits your fridge

everydrop’s own instruction, repeated in every genuine listing, is to pick the package that matches the number or letter and the color of the filter you already have. The table decodes those numbers using only what the 12 listings state. Heights come from listing product data and may include packaging.

Two things stand out. The numbers are not a quality ladder; Filter 4 is not better or worse than Filter 2, only shaped for a different housing. And the old part numbers still matter, because many fridges shipped with cartridges printed UKF8001, W10295370A or 4396395 rather than an everydrop number. If your cartridge shows one of those, the table ties it to the current number. A Filter 7 also exists in the family (EDR7D1); compatible listings for Maytag fridges cross-reference it to UKF7003, but it was not on this shelf; our Maytag refrigerator water filter guide covers it.

To confirm the right number, read the printed label on the cartridge you are replacing, then check the fridge’s model and serial label, usually on an interior side wall of the fresh-food section near the top or behind the crisper drawers. The owner’s manual or the manufacturer’s parts lookup lists the correct filter for that model number. None of the listings here says where the filter sits in a particular fridge, so do not choose from the housing location alone. Whirlpool owners can work through a model-by-model approach in our Whirlpool refrigerator water filter guide.

Genuine vs compatible

All six genuine everydrop refrigerator cartridges on this shelf name the same three standards: NSF 42, 53 and 401. Of the five compatibles, all name NSF 42; the two Waterdrop listings add NSF 372. None of the compatibles names 53 or 401. The ice machine filter names no standard.

• NSF/ANSI 42: aesthetic effects such as chlorine taste, odor and particulates.
• NSF/ANSI 53: health-related contaminants such as lead and cysts. The EPA’s lead-filter consumer tool says to look for certification against both 53 and 42.
• NSF/ANSI 401: emerging contaminants, such as some pharmaceuticals and trace chemicals.
• NSF/ANSI 372: lead-free materials in the filter itself. It is not a lead-reduction claim.

Read the verbs. “Certified by” an accredited body means a listing you can look up; “tested to” or “meets” can mean the seller’s own lab work. The CDC notes that you can look up a filter in the NSF database to see what it is certified to remove, and two Filter 1 compatibles here print an NSF certificate number for exactly that purpose.

everydrop’s listings warn that non-genuine filters may damage the refrigerator, and the ice machine listing says damage caused by a non-genuine filter is not covered by Whirlpool’s warranty. None of the 12 listings describes a chip that blocks third-party cartridges. The compatibles respond with fit and leak-free claims, which are their own statements.

The 6 picks, compared listing by listing

1. everydrop Filter 3 EDR3RXD1 — Best for Push-In Filter 3 Fridges

Best for Filter 3 fridges

Why we like it

• Claims 74 contaminants, second-highest here
• Names NSF 42, 53 and 401
• Only genuine listing stating a warranty term
• Push-in install, per listing

everydrop EDR3RXD1 — Filter 3, aqua, push-in, NSF 42/53/401, 74 contaminants, 6 months or 200 gal, 2-yr warranty

The Only Genuine everydrop Listing That States a Warranty Term

Seven listings on the shelf are genuine everydrop parts. Two of them, Filter A and Filter 5, fill the warranty field with the word “Warranty” and nothing else; the rest leave it blank. Filter 3 is the only one that states a term, a two-year manufacturer warranty. For a cartridge you replace every six months that may sound academic, but it gives a reference point if a new cartridge cracks or leaks at the housing.

It is one of only two push-in cartridges among the genuine filters, alongside Filter 1, and it is listed as the tallest at 13.5 inches. Its claim of 74 contaminants trails only Filter A’s 75. A compatible listing identifies Filter 3 by its older part number, 4396841, which helps if your current cartridge shows that number instead.

The listing does not name the 74 contaminants individually or give fridge model numbers. No Filter 3 compatible appeared on this shelf, so genuine is the only option shown.

2. everydrop Filter A EDRARXD1 — Best Newer Lettered Cartridge

Best newer lettered cartridge

Why we like it

• Highest contaminant claim on the shelf, 75
• Only letter-named cartridge in the line
• Names NSF 42, 53 and 401
• Twist-in install, per listing

everydrop EDRARXD1 — Filter A, twist-in, NSF 42/53/401, 75 contaminants, 6 months or 200 gal, 2024 listing

The Highest Contaminant Claim on the Shelf

The six genuine fridge cartridges claim 28, 32, 70, 70, 74 and 75 contaminants. Filter A tops the list. It is also the only cartridge named with a letter rather than a number, and its listing carries the most recent release date of the two genuine listings that give one, May 2024 against 2019 for Filter 4.

A higher count does not make Filter A a better choice for a fridge built around another number; it only fits a Filter A housing. What the letter does tell you is that the line is still growing, so a newer fridge may take a cartridge that older cross-reference charts do not show.

One inconsistency: the title calls it blue while the product data lists teal green. Neither the listing nor any compatible gives an older part number for Filter A, and no Filter A compatible appeared on this shelf.

3. everydrop Filter 2 EDR2RXD1 — Best Compact Twist-In Filter 2

Best compact Filter 2

Why we like it

• Shortest genuine cartridge listed, about 7.5 in
• Claims 70 contaminants
• Names NSF 42, 53 and 401
• Carries an extra model cross-reference, P9WB2L

everydrop EDR2RXD1 — Filter 2, orange, twist-in, NSF 42/53/401, 70 contaminants, 6 months or 200 gal

The Only Genuine Listing Whose Model Field Differs From Its Part Number

Every other genuine everydrop listing uses the part number as the model, EDR1RXD1 for Filter 1 and so on. Filter 2’s model field reads P9WB2L. That is useful if your old cartridge or manual shows P9WB2L rather than an everydrop number, since it ties the two together.

It is also the shortest of the genuine cartridges by listed height and among the lightest at 0.4 pound. The claim, 70 contaminants with NSF 42, 53 and 401, matches Filter 1 exactly. KitchenAid sells its own Filter 2 under part KAD2RXD1, and a compatible for that part lists a run of KitchenAid French-door models; if your fridge is a KitchenAid, the old cartridge will say which version you have, and our KitchenAid refrigerator water filter guide compares the two.

The listing names no fridge model numbers, and no Filter 2 compatible appeared on this shelf.

4. everydrop Filter 5 EDR5RXD1 — Best for Narrow Twist-In Filter 5 Housings

Best for Filter 5 fridges

Why we like it

• Genuine part for the Filter 5 slot
• Names NSF 42, 53 and 401
• Narrowest genuine cartridge listed
• Older part number 4396508 cross-referenced

everydrop EDR5RXD1 — Filter 5, pink, twist-in, NSF 42/53/401, 28 contaminants, 6 months or 200 gal

The Lowest Contaminant Count Among the Genuine Fridge Cartridges

Filter 5 claims 28 contaminants, the lowest of the six genuine fridge cartridges and just below Filter 4’s 32. Like Filter 4, the count matters only when you compare it with a Filter 5 compatible, because no other number fits a Filter 5 housing. It still names the same three NSF standards as the rest of the line.

Its listed width, 2.12 inches, is the narrowest of the genuine cartridges, and its height, 10.5 inches, puts it between Filter A and Filter 3. A compatible listing identifies it by the older number 4396508, which is what some older cartridges show.

No Filter 5 compatible appeared on this shelf; the one compatible listing that mentions Filter 5 does so to say it does not fit.

5. Waterdrop WD-F07 Filter 4 Compatible — Best Filter 4 Compatible Three-Pack

Best Filter 4 compatible

Why we like it

• Names Filter 4 fit brand by brand
• Names NSF 42 and NSF 372
• Three cartridges with month stickers
• Long list of old part numbers it replaces

Waterdrop WD-F07 — Filter 4 compatible, NSF 42 + 372, 300 gal or 6 months, stickers, 3-pack

The Only Compatible Here That Names KitchenAid and JennAir by Brand

Five of the 12 listings are third-party: three Filter 1 compatibles and two Waterdrop Filter 4 compatibles. This is the only one of the five that names KitchenAid and JennAir Filter 4 fridges by brand, alongside Whirlpool, Maytag, Amana and Kenmore. Its part-number list covers the whole UKF8001 family, which is why Filter 4 is the most cross-referenced number in the line.

Against the genuine Filter 4, the trade is certification for quantity. The genuine cartridge names NSF 42, 53 and 401; this one names NSF 42 for taste and odor and NSF 372 for lead-free materials. The listing’s heavy-metal and VOC language is “tested by the third-party laboratory,” which is testing, not certification for those contaminants.

Its rated 300 gallons is higher than the genuine 200, and it comes three to a pack with month stickers to track the change date.

6. everydrop ICE2 — Best for 50 lb Ice Maker Machines

Best for ice maker machines

Why we like it

• Genuine everydrop part for standalone ice makers
• Approved by Whirlpool, Maytag, KitchenAid and JennAir
• Longest stated interval here, 9 months
• Prevents buying a fridge cartridge by mistake

everydrop ICE2 — 50 lb ice maker machine filter, four brands, 9-month interval, NSF standards not listed

The Only Filter on the Shelf That Is Not for a Refrigerator

Searching for everydrop filters returns this cartridge alongside the fridge filters, and the two are easy to confuse. ICE2 is listed for 50 lb ice maker machines, not for the ice maker built into a refrigerator. It is the only listing of the 12 with a nine-month interval; every refrigerator cartridge says six months.

The listing says it is the only filter approved by Whirlpool, Maytag, KitchenAid and JennAir for those machines, and that damage from a non-genuine filter is not covered by Whirlpool’s warranty. It names no NSF standard and no contaminant count, so it cannot be compared with the fridge cartridges on certification.

Push-in vs twist-in: the quickest way to narrow the number

The genuine listings split into two install styles. Filter 1 and Filter 3 push straight in and latch. Filter 2, 4, 5 and A twist in and lock. If the printed number on your old cartridge has worn off, how it comes out removes half the options, and the color band (purple, orange, aqua, green, pink or blue) usually settles the rest.

A cartridge that needs force is the wrong one. Housings are plastic, and a near-fit pushed home can crack the head or leave a slow leak.

Replacement interval and the indicator light

Every genuine refrigerator cartridge on this shelf says six months or 200 gallons. The Filter 1 compatibles match that; the Waterdrop Filter 4 compatibles say 300 gallons or six months. Change at whichever limit comes first. The dispenser’s filter light is a timer, not a water-quality sensor; none of these listings describes a sensor. Reset it after each swap following the owner’s manual.

The CDC says to change filters on the manufacturer’s schedule so they keep working and germs do not grow in them, to wear gloves while changing them and to wash your hands afterward. It also advises people with weakened immune systems not to change filters themselves.

What an everydrop filter can and cannot do

everydrop cartridges are carbon filters. The CDC notes that most fridge and pitcher filters are not designed to remove germs; they typically use carbon to improve taste or reduce heavy metals like lead. If your water comes from a private well, the CDC recommends testing at least once a year, and a fridge cartridge is not a substitute for treating a well with a known problem.

Lead deserves its own check. The EPA notes that lead pipes are more likely in homes built before 1986 and that brass faucets and lead solder are common sources even without a lead service line. A genuine everydrop cartridge names NSF 53, the standard that covers health contaminants, but its lead performance is not spelled out in these listings. For targeted options, see our guide to filters for lead in water. The EPA also calls activated carbon the most studied treatment for PFAS, while noting that shorter-chain PFAS adsorb less well, so a broad PFAS claim on any small cartridge deserves scrutiny.

Front Range notes and when to call a pro

Front Range utilities publish an annual water quality report, and the CDC says reviewing it is the starting point for deciding what to filter. Hard water and sediment, common on some well systems, shorten cartridge life and can clog a fridge filter before its six-month date. If a new cartridge slows to a trickle quickly, the water upstream is the issue, not the filter.

Leaks around a filter housing or the supply line behind the fridge can go unnoticed for weeks, and a stained or soft floor in front of a refrigerator is a regular finding on home inspections. For whole-home and water-quality questions, our plumbing and water guides cover the next steps. Buying on the Front Range and want plumbing and leak evidence checked?
