  Only listing here naming coconut shell carbon

  Coconut shell carbon appears on one filter listing in this category. The others name carbon block or name no medium at all.

  everydrop Filter 1, EDR1RXD1

  6 month life statedListed here at position 01

  The listing states NSF 42, 53 and 401 certification, reduction of 70 contaminants including 99% microplastics, coconut shell carbon, 6-month life.

  Named on the listing: NSF/ANSI 42, 53, 401.The listing names all three standard numbers, which is why all three cells are filled.

  A genuine cartridge whose listing names all three standard numbers, which almost nothing else in this category does. The 70 contaminants and 99% microplastics figures are separate seller claims that sit beside the certification rather than inside it.

  What the listing gives you

  • All three standard numbers are named on the listing, not implied
  • Stated six month replacement interval
  • Names the filter medium, which most listings here do not
  • Genuine cartridge for the fridges the manufacturer lists

  What it leaves open

  • "70 contaminants" and "99% microplastics" are listing claims with no standard attached
  • A months-only interval ignores how much water you actually draw
  • Genuine cartridges are the expensive way to keep a fridge running

  Suits A Whirlpool-family fridge that takes the EDR1RXD1 cartridge.

  everydrop Filter 2, EDR2RXD1

  6 month life statedListed here at position 02

  The listing states NSF 42, 53 and 401 certification, reduction of 70 contaminants including 99% microplastics, 6-month life.

  Named on the listing: NSF/ANSI 42, 53, 401.The listing names all three standard numbers, which is why all three cells are filled.

  The Filter 2 cartridge, with the same three standard numbers named and the same six month stated interval. The cartridge shape is the difference from Filter 1, not the certification.

  What the listing gives you

  • All three standard numbers are named on the listing
  • Stated six month replacement interval
  • Same stated certification as the Filter 1 cartridge
  • Genuine cartridge for the fridges the manufacturer lists

  What it leaves open

  • The 70 contaminants figure is a listing claim, not part of the certification
  • A months-only interval ignores actual throughput
  • Cartridge number and fridge model still have to be matched by you

  Suits A Whirlpool-family fridge that takes the EDR2RXD1 cartridge.

  everydrop Filter 4, EDR4RXD1

  Listed here at position 03

  The listing states NSF 42, 53 and 401 certification and reduction of 32 contaminants including 99% microplastics.

  Named on the listing: NSF/ANSI 42, 53, 401.The listing names all three standard numbers, which is why all three cells are filled.

  The Filter 4 cartridge names the same three standard numbers as Filters 1 and 2 but states 32 contaminants rather than 70. That is the clearest example on this site of two numbers moving independently: the certification is identical, the seller's contaminant count is not.

  What the listing gives you

  • All three standard numbers are named on the listing
  • Shows plainly that a contaminant count and a certification are different things
  • Genuine cartridge for the fridges the manufacturer lists
  • Same stated standards as the higher-count cartridges in this family

  What it leaves open

  • This listing states no replacement interval at all
  • The contaminant count invites a comparison the certification does not support
  • "99% microplastics" is a listing claim with no standard attached

  Suits A Whirlpool-family fridge that takes the EDR4RXD1 cartridge.

  Only listing here stating a gallon figure

  200 gallons, and it is the one fridge filter listing in this category that states gallons rather than months alone.

  LG LT1000P Refrigerator Filter

  200 gallon rating statedListed here at position 04

  The listing states NSF 42, 53 and 401 certification, a 6-month or 200-gallon capacity.

  Named on the listing: NSF/ANSI 42, 53, 401.The listing names all three standard numbers, which is why all three cells are filled.

  A genuine LG cartridge that names all three standard numbers and states both a six month interval and a 200-gallon capacity. Stating both is the correct way to rate a filter, and it is why this listing is the one the filter life tool has the most to work with.

  What the listing gives you

  • States both a months figure and a gallon figure, so either can bind
  • All three standard numbers are named on the listing
  • Genuine cartridge for the fridges the manufacturer lists
  • A gallon figure lets a heavy-use household plan honestly

  What it leaves open

  • Two ratings means remembering that the earlier one is the one that applies
  • No filter medium is named on the listing
  • Genuine LG cartridges are the costlier route

  Suits An LG fridge that takes the LT1000P cartridge.

  GE XWFE Refrigerator Filter

  6 month life statedListed here at position 05

  No standard number is named on the listing. Not named: 42, 53, 401.The listing names NSF/ANSI without naming a standard number, so no cell is filled here.

  A genuine GE cartridge whose listing says NSF/ANSI standards without saying which ones, and separately claims lead and sulfur reduction plus 50+ impurities. This site does not turn an unnumbered mention into a numbered one, so all three chip cells stay empty here.

  What the listing gives you

  • Genuine cartridge for the GE fridges that take XWFE
  • Stated six month replacement interval
  • Names two specific substances rather than only a count
  • The most commonly stocked GE cartridge of the two here

  What it leaves open

  • No standard number is named, so the certification cannot be read
  • "50+ impurities" is a count with no standard behind it
  • No gallon capacity is stated

  Suits A GE fridge that takes the XWFE cartridge.

  GE RPWFE Refrigerator Filter

  6 month life statedListed here at position 06

  No standard number is named on the listing. Not named: 42, 53, 401.The listing names NSF/ANSI without naming a standard number, so no cell is filled here.

  The RPWFE cartridge carries the same unnumbered certification wording as the XWFE listing and the same six month interval. It is a different cartridge for different fridges, and the listing gives no more detail on standards than its sibling.

  What the listing gives you

  • Genuine cartridge for the GE fridges that take RPWFE
  • Stated six month replacement interval
  • Names two specific substances rather than only a count
  • Same wording as the XWFE listing, so nothing is hidden between them

  • No standard number is named, so the certification cannot be read
  • "50+ impurities" is a count with no standard behind it
  • No aftermarket alternative in this catalog states RPWFE compatibility

  Suits A GE fridge that takes the RPWFE cartridge.

  No standard number is named on the listing. Not named: 42, 53, 401.The listing names no certification, so no cell is filled here.

  A genuine Samsung cartridge with a stated six month life and no certification named anywhere in the listing. That is not a criticism of the cartridge; it is a statement about what the listing gives you to read.

  What the listing gives you

  • Genuine cartridge for the Samsung fridges that take HAF-QIN
  • Stated six month replacement interval
  • Short listing that claims nothing it does not support
  • No inflated impurity count to discount

  Only listing here naming a carbon block

  Carbon block appears on one filter listing in this category. The others name coconut shell carbon or name no medium.

  Samsung HAF-CIN Refrigerator Filter

  6 month life statedListed here at position 08

  No standard number is named on the listing. Not named: 42, 53, 401.The listing names no certification, so no cell is filled here.

  The other genuine Samsung cartridge, differing from its sibling by naming a carbon block medium. Like the HAF-QIN listing, it names no certification, so the chip shows three empty cells and says why.

  What the listing gives you

  • Genuine cartridge for the Samsung fridges that take HAF-CIN
  • Names the filter medium, unlike the other Samsung listing here
  • Stated six month replacement interval
  • Makes no claims it cannot support

  Only Frigidaire cartridge listed here

  Frigidaire appears on one filter listing in this category. Every other cartridge here is Whirlpool-family, GE, LG or Samsung.

  Frigidaire ULTRAWF Pure Source Ultra Filter

  Listed here at position 09

  The listing states an original Frigidaire filter.

  No standard number is named on the listing. Not named: 42, 53, 401.The listing names no certification, so no cell is filled here.

  The shortest listing in this category: an original Frigidaire cartridge, and nothing else stated. No certification, no interval, no medium. The trade name borrows a word that reads like an outcome, and a trade name is not a description of what comes out of the fridge.

  What the listing gives you

  • Stated as an original manufacturer cartridge
  • The only cartridge here for Frigidaire fridges
  • Nothing is overclaimed because almost nothing is claimed
  • Simple to match by cartridge code

  What it leaves open

  • No certification, no interval and no capacity are stated
  • The brand name includes a word that reads like a performance claim
  • Nothing on the listing to compare against another cartridge

  Suits A Frigidaire fridge that takes the ULTRAWF cartridge.

Aftermarket, compatibility stated by the seller

Three cartridges whose fit is stated by the seller rather than by the fridge manufacturer. Two name NSF/ANSI 42 and one names no standard. A narrower named standard is a real difference in scope, not a brand preference.

  Crystala XWFE Compatible Filter

  Listed here at position 10

  The listing states NSF/ANSI 42 certification and replacement for GE XWFE and XWF, with a built-in chip.

  Named on the listing: NSF/ANSI 42. Not named: 53, 401.The listing names NSF/ANSI 42 and no other number, so one cell is filled and two stay empty. Nothing here implies 53 or 401.

  An aftermarket cartridge whose listing names NSF/ANSI 42 and states it replaces GE XWFE and XWF. Naming 42 is more than the genuine GE listing manages, and it is also narrower than 42, 53 and 401 together. Both of those things are true at once.

  What the listing gives you

  • Names an actual standard number, which the genuine GE listing does not
  • States a built-in chip, which is what the fridge electronics look for
  • Names the two cartridge codes it is stated to replace
  • Makes the narrow scope legible instead of hiding it

  What it leaves open

  • NSF/ANSI 42 covers taste, odor and particulate, not the 53 and 401 lists
  • Compatibility is stated by this seller, not by the fridge manufacturer
  • No replacement interval and no gallon capacity are stated

  Suits A GE fridge owner who wants the standard number stated rather than implied.

  Named on the listing: NSF/ANSI 42. Not named: 53, 401.The listing names NSF/ANSI 42 and no other number, so one cell is filled and two stay empty. Nothing here implies 53 or 401.

  The second aftermarket XWFE cartridge here, with the same stated NSF/ANSI 42 certification and the same built-in chip. Two sellers, the same standard number, the same stated cartridge codes: the comparison on the XWFE page is between these two and the genuine cartridge.

  What the listing gives you

  • Names an actual standard number rather than a vague certification line
  • States a built-in chip for the fridge electronics
  • Names the two cartridge codes it is stated to replace
  • Gives the XWFE page a second aftermarket listing to read against

  What it leaves open

  • NSF/ANSI 42 alone is a narrower claim than 42, 53 and 401 together
  • Compatibility is stated by this seller, not by the fridge manufacturer
  • No replacement interval and no gallon capacity are stated

  Suits A GE fridge owner comparing two aftermarket cartridges on the same stated standard.

  The listing states replacement for LG LT1000PC, LT1000P/PCS and several LG refrigerator models.

  No standard number is named on the listing. Not named: 42, 53, 401.The listing names no certification, so no cell is filled here.

  An aftermarket combination pack stated to replace the LG LT1000PC and LT1000P/PCS cartridges, with an air filter included. No certification is named anywhere in the listing, which is the contrast with the genuine LG cartridge that names all three standard numbers.

  What the listing gives you

  • Includes the fridge air filter, which is a separate purchase otherwise
  • Names the specific LG cartridge codes it is stated to replace
  • A combination pack covers two replacement schedules at once
  • Makes the gap against the genuine cartridge easy to see
