Overview
A 3-pack of NSF 42 and NSF 372 certified refrigerator water filters built from coconut shell carbon block, made as a replacement for Whirlpool EDR4RXD1, EveryDrop Filter 4, and Maytag UKF8001 filters.
This is specifically the Filter 4 replacement family - it is not compatible with Filter 1, 2, 3, 5, or 6, so matching the exact filter number your fridge takes matters more than the brand name on the box. The listing includes install-date stickers so the 6-month or 300-gallon replacement window is easy to track.
- 3-pack, NSF 42 and NSF 372 certified
- Coconut shell carbon block filtration
- Tool-free replacement, no tools required
- Rated for 6 months or 300 gallons per filter
Who it's for
Owners of Whirlpool, Maytag, Amana, or Kenmore refrigerators that take the EDR4RXD1 or EveryDrop Filter 4, who want a lower-cost 3-pack instead of buying the branded filter one at a time. Not for fridges that use Filter 1, 2, 3, 5, or 6, which use a different cartridge shape.
What buyers say
From Amazon customer reviews.
Buyers consistently say the fit matches the original Whirlpool filter with no leaks and that the water tastes clean with no aftertaste, several noting they've repurchased the same filter for years. The main value point raised is cost, with more than one reviewer pointing out the 3-pack costs less than a single branded filter from the appliance store.
Strengths and trade-offs
Drawn from this product's published specifications.
- Fits only the Filter 4 family, not others
- Needs a short flush before water tastes right
Performance notes
The coconut shell carbon block is described as having a larger surface area and more micropores than standard charcoal filters, which the listing ties to better taste and broader reduction of chlorine, heavy metals, and other contaminants tested by a third-party lab. Installation is tool-free, and Waterdrop recommends running the dispenser for about five minutes after installation to clear the system before the water tastes right.
