Do Refrigerator Water Filters Remove Microplastics?
Check the cartridge, the refrigerator and the certified claim before buying a replacement. A familiar brand name alone cannot answer all three.

Do refrigerator water filters remove microplastics?
Some refrigerator filtration systems have a certified microplastics-reduction claim. That does not make every cartridge compatible with your fridge—or give every filter the same performance. Check the replacement part and the installed filtration system together.
Everydrop Filter 1 is one documented example: the current W11392626F performance sheet includes replacement cartridge EDR1RXD1 and reports an average 99.9% microplastics reduction under its laboratory conditions. That is a defined test result, not a promise of zero plastic particles in every glass.
If your refrigerator already has a suitable filtration system, checking its replacement cartridge is a practical first step. If it does not, our pitcher and water-filter comparison covers separate devices you can choose without matching a refrigerator.
The best refrigerator filter starts with the one that fits
A refrigerator cartridge is a replacement part for an existing appliance. A highly rated product for a different socket is not an upgrade. Start with the appliance's complete model number, including its suffix, and the replacement part specified by the manufacturer.
For Everydrop, use the manufacturer's Check Fit or Filter Finder. Whirlpool, Maytag, KitchenAid, Amana and JennAir each use more than one filter format; the logo on the refrigerator is not enough. An old cartridge can help identify what is installed, but cross-check the appliance instructions instead of assuming the previous replacement was correct.
| Write down | What it answers | Where to check |
|---|---|---|
| Refrigerator model | Which replacement is approved for this appliance? | Appliance label, manual and maker's fit finder |
| Cartridge part number | Which exact replacement am I buying? | Product listing and package |
| Filtration-system model | Which certification and service rating apply? | Appliance performance sheet and certifier listing |
Keep these three identifiers in one note. If the names in the listing and manual do not line up, resolve that mismatch before buying. A photo of a similar-looking cartridge is a weaker check than matching the part number.
A verified example: one cartridge, two system ratings
The NSF/ANSI 401 microplastics directory lists the following combinations. Both use EDR1RXD1, but their listed service cycles differ.
| Listed system | Replacement | Service cycle | Microplastics claim |
|---|---|---|---|
| P8WB2L | EDR1RXD1 | 200 gallons | Listed |
| W11602565 | EDR1RXD1 | 100 gallons | Listed |
NSF identifies W11602565 as a system without a Performance Indicator Device. The manufacturer's sheet also distinguishes systems with and without that device. Do not assign the larger capacity from the cartridge name alone. Confirm the system in your appliance's documentation; a generic filter-status light is not enough to make that identification.
This distinction matters when budgeting replacements. At the same cartridge price, a lower applicable volume rating can mean more replacements at high usage. It does not mean microplastic reduction suddenly stops at a particular gallon count, or that the larger-rated system removes twice as many particles.
When Everydrop Filter 1 is a relevant option
For compatible refrigerators · fit check required
Everydrop EDR1RXD1, Purple Filter 1, one-pack
This is a reasonable replacement to consider when your refrigerator calls for EDR1RXD1 and its system matches the documentation above. The benefit is a traceable claim for a named configuration, rather than a general promise attached to the word “carbon.”
The linked Amazon variant is 1 Count (Pack of 1). It is a plastic cartridge, not a plastic-free water path. The manufacturer describes a push-in installation; use your refrigerator's procedure instead of treating the steps for another filter number as interchangeable.
Check before ordering: exact part, pack size, seller and current price. Our recommendation is conditional on fit. We have not compared its flow, taste, durability or particle reduction against competing cartridges in our own tests.

Four checks that matter more than a “best filter” badge
- Find the named reduction claim. Look for microplastics in the listing for the exact system and replacement. Do not stop at a standard number or a logo on a shopping graphic.
- Separate fit from treatment. “Replaces EDR1RXD1” describes a compatibility claim. It does not let a different manufacturer's cartridge borrow the Everydrop system's test result. Verify that alternative's own evidence.
- Read the conditions beside the percentage. A reduction figure needs its test context. Avoid ranking unrelated filters solely by which marketing percentage has more nines.
- Check the purchase you will actually receive. Search results can mix genuine cartridges, alternative brands and multipacks. Open the listing and confirm the selected variant, rather than ordering from the search-card title.
You may also need treatment for something other than plastic particles. NSF advises starting with your water-quality information and checking the contaminants a particular filter reduces. One successful claim does not establish performance for every other substance.
Plan replacements before choosing a multipack
The Everydrop performance sheet requires replacement at least every six months, with the appliance's instructions governing installation and operation. It also calls for flushing after a change and specifies cold, potable water. Follow any earlier replacement trigger in your manual; this cartridge is not a substitute for disinfecting microbiologically unsafe water.
Compare the price per cartridge after checking the pack size, then budget using your applicable time and volume limits. A low advertised price per gallon is not very useful if your household reaches the time limit long before using the rated volume.
Keep the installation date with your three model identifiers. Reset the indicator only as the appliance instructions direct after replacing the filter: resetting the light does not clean or renew the cartridge. A recurring calendar reminder can help, but it should not replace a model's earlier service indication.
Does this establish nanoplastic removal?
No universal nanoplastic claim is established here. A documented microplastics result should not be extended to every smaller particle without supporting evidence. If nanoplastics are the deciding issue, see our guide to RO and nanoplastic evidence for the size and whole-system test details to request.
Refrigerator filter questions
Does every NSF-certified refrigerator filter reduce microplastics?
Do not assume so. Check for the specific microplastics-reduction claim against the exact system and replacement cartridge.
Can I buy Filter 1 for any Whirlpool refrigerator?
No. Use the complete refrigerator model in the manufacturer's fit finder or manual. Brand and cartridge color alone are insufficient.
Does a compatible replacement inherit the original filter's certification?
No. Check the alternative manufacturer's own model and certification. Matching a socket does not establish an identical reduction claim.
Should I replace the refrigerator to get filtered water?
Start by checking the appliance you already own. If its filtration options do not meet your needs, compare a separate appropriate filter before treating a new refrigerator as the solution.
