What is EveryDrop Filter 4?
EveryDrop Filter 4 is a refrigerator water filter cartridge designed to help improve the taste and clarity of your drinking water and ice by reducing certain impurities. You’ll often see it connected with Whirlpool-family refrigerators, which is why some shoppers also refer to it as a Whirlpool refrigerator filter.
The most reliable way to identify it is the part number, not the wording used in a store listing.
How to confirm you need EDR4RXD1 (before you buy)
A two-minute check can save you a return later.
First, pull out your current filter and look for the printed code. If it reads EDR4RXD1, you’re good to go. If the label is faded or missing, check your refrigerator manual under Water Filter or Replacement Parts. Some models also have a small label near the filter housing that indicates what you need.
If you still can’t confirm it, use your refrigerator model number (on the sticker inside the fridge compartment) to verify compatibility before ordering.

| Taste/odor returns | Water starts tasting or smelling off | Replace the filter and flush thoroughly |
| Slow dispensing | Water flow becomes noticeably weaker | Re-seat the filter; if it doesn’t improve, replace it |
| Filter light alert | Replace Filter or similar message | Replace the filter and reset the indicator (varies by model) |
How to install EveryDrop Filter 4 (EDR4RXD1) without the usual problems
The filter can be located in different places depending on your refrigerator (top corner inside the fridge, side wall, or bottom grille). The actual replacement process is usually similar just don’t rush the fully seated step, because that’s where most leaks and low-flow issues come from.
- Locate the filter housing and open the compartment door (if your model has one).
- Remove the old filter (push-to-release or twist-and-pull depending on your refrigerator).
- Remove any protective caps/seals from the new filter.
- Insert the new EDR4RXD1 and push or twist until it’s fully seated (you should feel a firm stop or click).
- Flush the system by dispensing and discarding water until it runs steady and clear (follow your refrigerator’s recommended flush amount).
- Reset the filter indicator light using your refrigerator’s control panel instructions.
Common Issues After Installing a new Filter (Quick Fixes that Actually Work)
- Low water flow right after replacement: This is often trapped air flush longer first, then re-seat the filter to make sure it’s locked in.
- Leaking at the filter housing: Most leaks happen when the filter isn’t fully seated or a protective cap is still on, remove it, check packaging, and reinstall firmly.
- Water tastes “off” at first: Usually a flushing issue flush more water and discard it until taste stabilizes.
