Whirlpool P8RFWB2L Refrigerator Water Filter
The short answer on the P8RFWB2L
P8RFWB2L is the PUR-branded version of the Whirlpool Filter 1 cartridge — the P prefix marks the PUR retail line Whirlpool co-marketed for fast-fill dispensers. The bay is the standard Filter 1 push-in housing, and the current EveryDrop EDR1RXD1 covers it. It carries 42+53+401 (series claim). Succession: P8RFWB2L = PUR-branded Filter 1 slot (EDR1RXD1 successor line).
The fit list below draws on 107 refrigerator models checked one by one in our library. Install time: 5 minutes, no tools. The P8 first letter in a Whirlpool-family part number almost always means PUR retail packaging rather than a different cartridge; match the rest of the code against your plate, not the brand on the box.
P8RFWB2L vs EDR1RXD1 vs W10295370A — same bay or different?
| Cartridge | What it is | Chip | Claim set | Path |
|---|---|---|---|---|
| P8RFWB2L | PUR-branded Filter 1 slot | No chip | PUR retail era claims | Same bay as EDR1RXD1 |
| EDR1RXD1 | Filter 1, in production today | No chip | Series claim: 42+53+401 | The production number for this slot |
| W10295370A | Whirlpool-numbered predecessor | No chip | 42+53 | Same bay, pre-EveryDrop numbering |
| 9081 | Sears catalog number | No chip | Same cartridge as EDR1RXD1 | Kenmore dress for the same slot |
Every claim line above comes from the part-number evidence file; compatible cartridges usually carry a smaller claim set than the OEM column shows.

Swap it in 5 minutes
- Press the release tab and draw the spent cartridge straight down and out — a couple of drips is normal.
- Match the new cartridge's keying to the slot; it seats in only one orientation.
- Push until the latch catches with a click.
- Flush 1–2 gallons through the dispenser to clear carbon fines, then hold filter reset until the light goes out.
What the P8RFWB2L is actually certified to remove
NSF/ANSI 42 + 53 on this line, with 401 passed across the series Honest framing for buyers: compatibles split into 42-only (taste, chlorine, sediment) and 42+53 (adds tested lead and cyst reduction) — that second tier is the one worth paying for. Claims are part-number × version facts — NSF listings update with annual re-tests, so re-check the certified-product database before relying on a claim. PFOA/PFOS reduction claims live under NSF/ANSI 53 (P473 protocol), not under 401 — a listing that says otherwise is wrong.
Is the P8RFWB2L the same as EveryDrop Filter 1?
Same slot. P8RFWB2L is the PUR-branded run of the Filter 1 bay; EDR1RXD1 is the number Whirlpool keeps in production today. Either seats in the same push-in housing.
Does the PUR P8RFWB2L have a chip?
No. The PUR name on a Whirlpool-family cartridge is a retail brand, not an electronics package — no chip, no pairing, no dispenser lock-out.
Why does my fridge plate show a W-number but the box says PUR?
Whirlpool sold one cartridge family under two retail brands during the Fast-Fill era. The bay only cares about the slot geometry — both the W-number and the P-number trace back to the same push-in Filter 1 position.
What certification should a compatible replacement carry?
NSF/ANSI 42 + 53 to track the OEM series claim set. A compatible listing that cites only 42 covers taste and chlorine; lead and cyst reduction come from the 53 claim.
