everydrop filter 1 vs 3 vs 4 vs 5: how to find the right one for your fridge

Quick answer: everydrop filter numbers refer to shapes, not quality. Filter 1 (EDR1RXD1) and Filter 3 (EDR3RXD1) go inside the fridge. Filter 5 (EDR5RXD1) is in the bottom grille. Filter 4 (EDR4RXD1) replaces the older UKF8001 twist-in style. Check the label on your current filter for the exact number.

Whirlpool’s everydrop filters are numbered — but the numbers don’t mean what you think

Filter 1, 3, 4, 5 — these numbers refer to filter shapes and fridge generations, not quality levels. Filter 3 is not better than Filter 1. They are simply different sizes for different refrigerator models. Here’s how to tell them apart.

How to find which everydrop filter number you need

Check your current filter label — it will say EDR1RXD1, EDR3RXD1, EDR4RXD1, or EDR5RXD1. As a quick rule: if the filter is inside the fridge, it’s likely Filter 1 or 3. If it’s in the bottom grille, it’s likely Filter 5. Filter 4 replaces the older UKF8001 twist-in design.

Frequently asked questions

What is the difference between everydrop Filter 1 and Filter 3?

Filter 1 (EDR1RXD1) and Filter 3 (EDR3RXD1) are different sizes designed for different Whirlpool refrigerator models. They are not interchangeable. Check your current filter label to confirm which one your fridge uses.

Is everydrop Filter 4 the same as Maytag UKF8001?

Yes. The everydrop EDR4RXD1 Filter 4 is the direct replacement for the Maytag UKF8001 and PUR Puriclean II filters. All three fit the same refrigerators.

Why does everydrop skip Filter 2?

everydrop Filter 2 (EDR2RXD1) exists but is less common — it fits select Whirlpool French-door models with a specific filter housing shape. If you don’t see Filter 2 on your fridge, it likely uses a different filter number.

Do all everydrop filters fit Kenmore refrigerators?

It depends on the Kenmore model. Kenmore refrigerators made by Whirlpool use everydrop-compatible filters. Check your Kenmore model number to confirm: models 9081, 9083 use compatible Filters Fast filters, while some Kenmore models use everydrop directly.
