Which EveryDrop Filter Do I Need? EveryDrop Filter Numbers 1–6, A & Legacy Part Numbers

If you still have the old cartridge, start with the filter number printed on it. If you don't, find your refrigerator's complete model number and run it through our Filter Finder. EveryDrop currently sells Filter A and Filters 1 through 8, each with a specific part number such as EDR1RXD1 or EDR4RXD1. Older Whirlpool-family cartridges may appear under codes like UKF8001 or 4396508. The filter numbers are not interchangeable, so confirm the exact part number before ordering.

How to Find Which EveryDrop Filter You Need

The printed number on your existing cartridge is the quickest, most reliable way to identify your filter. If you don't have it, your refrigerator's complete model number is the manufacturer-supported fallback.

Identification hierarchy

1. The filter number printed on your current cartridge — quickest and most reliable.

2. Your refrigerator's complete model number — the manufacturer-supported route when the old filter is gone.

3. Color and physical design — supporting confirmation, not a primary method. If you can still see your old filter, its printed filter number is the quickest identifier; color and cartridge design help confirm the match rather than determine it on their own.

Decision tree:

Do you have the old filter?

├─ YES → Read the EDR number or legacy part number

│         → Cross-reference against Table 2

└─ NO  → Find your refrigerator model number (inside the door frame)

          → Run it through our Filter Finder

Still unsure?

└─ Check filter location and installation style (see "Where Is the EveryDrop Filter" below)

   → Confirm against your model or part number

Where to find the number on your filter

The filter number and color are printed directly on the cartridge body, typically near the top where it seats into the housing.

Where to find your refrigerator model number

The complete model number is commonly printed inside the door frame, on a label visible when the door is open. Use the full number, including any trailing letters or digits.

Still can't identify it?

Start with our Filter Finder. EveryDrop also operates its own Filter Finder tool at everydropwater.com as the manufacturer's official lookup, or you can call 1-800-253-1301 for support.

What Does the EveryDrop Filter Number Actually Mean?

The EveryDrop filter number identifies a specific cartridge and fitment. It does not indicate that one filter is stronger or more advanced than another.

Why you can't choose based on filtration level

Compatibility depends entirely on your refrigerator's physical filter housing, not the number. A higher filter number isn't an upgrade tier the way a newer phone model might be; Filter 5 isn't "better" than Filter 1, it simply fits a different set of refrigerators.

What actually differs between filters

Physical dimensions, mounting style, and which specific refrigerator models each cartridge fits are what genuinely distinguish one EveryDrop filter from another, not filtration strength.

Contaminant counts by filter

Reduction claims do vary by filter, and these figures come directly from EveryDrop's own product data: Filter 1 is certified to reduce 70 contaminants, Filter 3 reduces 74, Filter 5 reduces 28, and Filter A reduces 75, each including 99% microplastics reduction. These differences reflect each filter's specific tested media and certification scope, not a simple better-to-worse ranking.

EveryDrop Filter Numbers Explained

Each EveryDrop filter has its own part number, color, and set of cross-referenced codes, verified against EveryDrop's own product pages.

Table 1. Master Filter Table (verified against everydropwater.com, whirlpool.com, amana.com)

A note on Filter 6's two codes: EveryDrop's own Filter Finder tool returns both EDR6D1 and EDR6RXD1 as valid results for Filter 6, but only EDR6D1 has an active standalone product page on everydropwater.com. We could not establish a documented functional distinction between the two codes within this research pass; treat them as the same filter family unless your specific Filter Finder result for your model specifies otherwise.

EveryDrop Filter 1 (EDR1RXD1)

Filter 1 is purple, part number EDR1RXD1, and replaces Whirlpool part W10295370A. It's certified to reduce 70 contaminants, including 99% of microplastics, under NSF/ANSI Standards 42, 53, and 401. It's also cross-referenced as WHR1RXD1, KAD1RXD1, P4RFWB, and P8RFWB2L across the Whirlpool-family brands.

EveryDrop Filter 2 (EDR2RXD1)

Filter 2 is orange, part number EDR2RXD1, and replaces Whirlpool part W10413645A. It's certified under the same NSF/ANSI 42, 53, and 401 framework as EveryDrop's other current filters. Filter 2 carries meaningful search demand of its own, distinct from Filter 1 and Filter 3, so don't assume it's simply an alternate version of either; it has its own dedicated part number, its own physical cartridge, and its own set of compatible refrigerator models. If you're replacing an orange-labeled cartridge, EDR2RXD1 is the correct current part number to search for, and W10413645A is the legacy Whirlpool number it superseded.

EveryDrop Filter 3 (EDR3RXD1)

Filter 3 is aqua, part number EDR3RXD1, certified to reduce 74 contaminants including 99% of microplastics. It's cross-referenced as 4396841, 4396710, W10193691, KAD3RXD1, and WHR3RXD1.

EveryDrop Filter 4 (EDR4RXD1)

Filter 4, part number EDR4RXD1, is the current replacement for the discontinued UKF8001, also known as Puriclean II. It's cross-referenced as UKF8001AXX, 4396395, Kenmore 46-9006 and 46-9084, and FMM-2. EveryDrop rates it for 6 months or 200 gallons, whichever comes first.

EveryDrop Filter 5 (EDR5RXD1)

Filter 5 is pink, part number EDR5RXD1, certified to reduce 28 contaminants including heavy metals, pesticides, and 99% of microplastics. It's cross-referenced as 4396508, 4396510, 4392857, and WF285.

EveryDrop Filter 6 (EDR6D1 / EDR6RXD1)

Filter 6's current part number is EDR6D1, and it replaces Whirlpool part 4396701, also cross-referenced as WF-NL120V and WF-L200V. It installs behind the lower front grille and requires a quarter turn to remove, a different mounting style from the interior-mounted filters above.

EveryDrop Filter A (EDRARXD1)

Filter A is blue, part number EDRARXD1, certified to reduce 75 contaminants including 99% of microplastics, the highest published contaminant count among EveryDrop's current lineup. It's designed for specific ice and water filtration systems across the Whirlpool-family brands.

EveryDrop Filters 7 and 8

Filters 7 (EDR7D1) and 8 (EDR8D1) are still sold through brand channels, though they aren't featured on everydropwater.com's main consumer product lineup page. Filter 7 replaces UKF7003; Filter 8 is cross-referenced as 8171413 and 8171414. If your refrigerator takes one of these, they aren't discontinued; they're simply positioned outside the primary product listing, which makes them harder to find than the numbered lineup above. Search by the exact part number (EDR7D1 or EDR8D1) rather than assuming your refrigerator has been orphaned.

EveryDrop Part Number Cross-Reference

Many EveryDrop filters carry older Whirlpool-family part numbers that are still correct, just renamed under the EveryDrop brand.

Table 2. Part Number Cross-Reference

These headers are deliberately neutral. A code in the left column isn't necessarily "old" or "superseded"; UKF8001 → EDR4RXD1 → Filter 4 is the same physical cartridge under its current EveryDrop branding, still a correct and current part.

Table 3. Kenmore Cross-Reference

Why the part numbers changed

Whirlpool consolidated Whirlpool, Maytag, KitchenAid, Amana, and JennAir filters under the shared EveryDrop brand, which is why older, brand-specific numbers now map to a single current EveryDrop part.

Is your old part number still correct?

Yes. If your existing filter or manual shows an older code like UKF8001 or 4396508, it's the same cartridge as its current EveryDrop equivalent, just under different branding.

Does my Kenmore use an EveryDrop filter?

Only if your Kenmore refrigerator was built by Whirlpool. Not every Kenmore appliance shares a manufacturer, so check your specific model number against Table 3 above rather than assuming Kenmore ownership alone determines the answer.

Where Is the EveryDrop Filter in Your Fridge?

Location depends on your specific filter and refrigerator, and this is an area where competing guides frequently disagree with each other.

Interior, upper right of the fresh food compartment

This is the most common location across EveryDrop's interior-mounted filters, accessed with either a push-button release or a twist-off cap depending on the specific model.

Behind the base grille

Filter 6 specifically installs behind the lower front grille, with a quarter-turn removal mechanism, according to EveryDrop's own product documentation. This is a distinctly different mounting style from the interior-mounted filters.

How mounting style narrows down your filter

Confirming whether your refrigerator has an interior twist-in filter, an interior push-button filter, or a base-grille filter helps narrow down which EveryDrop number applies, but it's a confirmation step, not a substitute for checking the actual part number.

Which Brands Use EveryDrop Filters?

EveryDrop is the shared filtration brand across every refrigerator Whirlpool manufactures, regardless of which nameplate the refrigerator itself carries.

Whirlpool, Maytag, KitchenAid, Amana and JennAir

All five brands are Whirlpool-built, and EveryDrop is the official filter line across the entire group. A specific EveryDrop filter number can apply across multiple brand nameplates simultaneously, since the underlying refrigerator platform, not the brand name, determines the filter housing.

Kenmore

Only Whirlpool-built Kenmore refrigerator models use EveryDrop filters. Check your specific model number against Table 3 above to confirm.

Cross-brand equivalents

EveryDrop Filter 4 (EDR4RXD1) is the direct current replacement for the Maytag-branded UKF8001, illustrating how one EveryDrop number can replace a filter originally sold under a different brand name entirely. For brand-specific replacement guides, see our articles on Amana refrigerator filters and Fisher & Paykel filters.

Are EveryDrop Filters Interchangeable?

No, not across different filter numbers, even within the same brand family.

Table 4. Interchangeability

The rule

EveryDrop filters share a brand name, not a housing. Each numbered filter has its own physical body, built for a specific set of refrigerator models.

What happens if you install the wrong filter

Installing a filter that doesn't match your housing can cause leaks, poor seating, restricted or no water flow, or a cartridge that simply won't lock into place at all.

Genuine EveryDrop vs. Comparable Filters

Whether a comparable filter is a safe choice depends on verifying fit and certification, not on brand loyalty alone.

Table 5. Pricing (confirm live prices and stock at publish)

What's documented about compatibility

No electronic authentication requirement is documented for EveryDrop cartridges, unlike certain other refrigerator filter brands that use an RFID chip to verify genuine parts. That absence doesn't establish that every third-party comparable filter performs safely or fits correctly across the range; it simply means the failure mode is different, physical fit and certification rather than electronic recognition.

What to verify before buying a comparable

Confirm the exact physical fit, the correct part-number match, NSF/ANSI 42, 53, and 401 certification, the stated capacity rating, and explicit refrigerator compatibility before choosing a comparable filter over a genuine one.

What Whirlpool says

Whirlpool states that non-genuine filters may damage the refrigerator. This is manufacturer guidance, worth taking seriously, not an independent finding we're presenting as our own conclusion. Use the verification checklist above to judge any specific comparable filter on its own documented merits.

Replacing and Resetting an EveryDrop Filter

Installation is push-in and tool-free across EveryDrop's current lineup.

Installation

Flush 2 to 3 gallons of water through the dispenser after installing a new filter to clear trapped air and carbon fines. If flow stays slow afterward, remove and reinstall the cartridge to confirm it's fully seated.

Resetting the indicator

The reset method varies by brand and control panel. See our brand-specific guides for Amana filter reset instructions rather than assuming one universal sequence applies.

How often

EveryDrop's own figure is 6 months or 200 gallons, whichever comes first.

Frequently Asked Questions

Which EveryDrop filter do I need?

Check the number printed on your current cartridge first. If you don't have it, look up your refrigerator's complete model number using our Filter Finder or EveryDrop's own lookup tool.

What does EDR1RXD1 mean?

EDR1RXD1 is the part number for EveryDrop Filter 1, a purple cartridge that replaces the older Whirlpool part number W10295370A. It's a specific fitment identifier, not a quality tier.

Can I use an EveryDrop Filter 1 instead of Filter 4?

No. Filter 1 and Filter 4 have different physical dimensions, and installing the wrong one can cause leaks or prevent the filter from seating correctly, even though both are interior-mounted cartridges.

How do I find my EveryDrop filter if I don't have the old filter?

Locate your refrigerator's complete model number, printed inside the door frame, and run it through our Filter Finder or EveryDrop's own Filter Finder tool.

Is EDR4RXD1 the same as UKF8001?

Yes. EDR4RXD1 is the current EveryDrop part number for the same physical cartridge previously sold as UKF8001, also known as Puriclean II.

Where is the EveryDrop filter located in my refrigerator?

Most EveryDrop filters install inside the fresh food compartment, commonly in the upper right area. Filter 6 specifically installs behind the lower front grille instead, with a quarter-turn removal mechanism.

Do Kenmore refrigerators use EveryDrop filters?

Only Kenmore models actually built by Whirlpool. Check your specific model number against our Kenmore cross-reference table to confirm, since not every Kenmore appliance shares a manufacturer.

Do generic EveryDrop filters work?

Some do, if they match your exact part number, physical fit, and NSF/ANSI 42, 53, and 401 certification. No RFID or electronic authentication requirement is documented for EveryDrop cartridges, but that doesn't guarantee every comparable filter performs safely; verify each specific product's documented specs before buying.
