Everydrop Filter 1 is EDR1RXD1; Filter 4 is EDR4RXD1. The number names a cartridge family. It does not make Filter 4 a newer replacement for Filter 1.
Whirlpool specifies EDR1RXD1 for WRS325SDHZ, WRS571CIHZ and WRS315SDHM in the model comparison linked below. Its WRF535SWHZ specification identifies EDR4RXD1 instead. The refrigerator model decides which code to use.
GE specifies XWFE for GNE27JYMFS and GFE26JYMFS. Other GE filter families include RPWFE and MWF; the shared GE name does not make those cartridges interchangeable with XWFE.
A manufacturer replacement relationship has a direction. GE lists XWFE as a replacement for XWF in its cartridge catalogue. That statement does not make an arbitrary similar cartridge a replacement for XWFE.
At checkout, compare the full reference, brand and pack quantity. The model pages offer separately checked Amazon product identities for XWFE, EDR1RXD1 and EDR4RXD1. A similar reference or a generic replacement claim does not establish the same cartridge.
