The short answer on the PH21500

PureH2O PH21500 is a third-party cartridge number, not a Whirlpool factory code: the PH2 line is a compatible brand built around the Filter 4 bay that the OEM serves as EDR4RXD1 and Sears catalogs as 9006/9084. Searching PH21500 usually means one of two things — replacing a PH21500 you already own, or checking what an equivalent cartridge should cost and carry. It carries no NSF claim stated in our evidence file. Path: PureH2O PH21500 → compatible for the EDR4RXD1 (Filter 4) slot.

Cross-checked fit coverage: 639 refrigerator models in the library behind this site. Install time: 5 minutes, no tools. When moving from a third-party number to any replacement, match the slot (Filter 4 bay, French-door top-left position), then buy on stated claims — the brand on the box matters far less than the certification line under it.

PH21500 vs EDR4RXD1 vs 9006 — which cartridge does your fridge take?

Claim lines are part-number × version facts from our evidence file — compatibles typically stop lower on the certification ladder.

What a PH21500 should cost

Because the PH21500 is a compatible-brand number rather than a factory part, no OEM anchor price exists — the seller's listing is the live price. Market-wide, compatibles sit at $8–15 in the 42-only band, with a smaller 42+53 premium tier above.

ClearFit pricing follows a competitor −10% formula and is published per SKU once the product line goes live — no placeholder prices on this page.

The plate inside the fresh-food compartment carries your fridge's model number. Every system in the family is listed at the PureH2O filter hub.

Swap it in 5 minutes

Installing the PH21500 Water Filter water filter
  • Pull the old cartridge straight out of the header — expect a small spill, not a flood.
  • Align the new cartridge with the keyed slot; it only goes in one orientation.
  • Push the cartridge home until the retention latch clicks.
  • Run 1–2 gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.

What the PH21500 is actually certified to remove

Old cartridge vs new — when to swap

No NSF claim stated in our evidence file for this part number — check the NSF certified-product listing before relying on any claim. The honest framing: the two tiers that matter in compatibles are 42-only (taste, chlorine, sediment) and 42+53 (adds tested lead and cyst reduction). A claim is a part-number × version fact, and NSF listings move with annual re-tests — verify in the certified-product database before you rely on one. And note the PFOA/PFOS reduction claim sits under NSF/ANSI 53 (P473 protocol), never under 401, whatever a listing says.

Is the PureH2O PH21500 an OEM Whirlpool filter?

No. PH21500 is a third-party model code; the OEM cartridge for the bay it fits is EveryDrop Filter 4 (EDR4RXD1). Neither Whirlpool nor Sears ever used the PH21500 number.

What does the PH21500 replace?

It is built as a compatible for the Filter 4 slot — the bay served by EDR4RXD1 and cataloged by Sears as 9006 and 9084. Any of those cartridges seats in the same push-in position.

Does the PH21500 have a chip?

No — and neither does the OEM cartridge it copies. No cartridge in this Whirlpool/Kenmore slot family verifies electronically.

What should I check before reordering a PH21500?

The certification line on the current box. We hold no verified NSF claim for this number in our evidence file, so treat any claim as the seller's until checked against the NSF certified-product database — the OEM reference for this bay carries 42+53+401/372.
