What to match before buying

  • The manufacturer specification for WRS315SDHM identifies EDR1RXD1. This record covers that US model code.
  • The Everydrop number identifies the cartridge family. Filter 1 and Filter 4 are not interchangeable generations.
  • The Amazon option was checked for the named reference. Compare the final reference, seller and pack quantity before ordering.
Find the model and filter codes
  1. Find the rating label inside the refrigerator and photograph the complete model code.
  2. Compare the label with WRS315SDHM. Retain any additional revision digits or suffixes for a separate manufacturer check.
  3. Read EDR1RXD1 on the existing cartridge or the manufacturer filter specification.
  4. Compare the cartridge reference and pack on the final Amazon page, including after a country redirect.
Other models and cartridge variants
  • A related model name or a similar connector does not establish another fit. Additional model suffixes need their own source.
  • This record covers US specifications. A local Amazon item does not approve another regional refrigerator model.
