EveryDrop Filter 1 vs Filter 2: Which One Fits Your Fridge? (EDR1RXD1 vs EDR2RXD1)

If your refrigerator has started tasting like a swimming pool, you already know it is filter time. The hard part is not whether to replace it — it is figuring out whether your fridge takes EveryDrop Filter 1 (EDR1RXD1) or EveryDrop Filter 2 (EDR2RXD1). They look almost identical on the shelf, they cost about the same, and they are absolutely not interchangeable.

This guide breaks down the real differences, shows you three quick ways to identify the correct filter for your model, and tells you exactly what to order so you are not stuck with the wrong cartridge and a fridge that still drips.

Quick answer: Filter 1 vs Filter 2 at a glance

Both are twist-in cartridges that sit in the top right corner of the fresh food compartment. Both are rated for roughly 6 months or 200 gallons. Both carry NSF/ANSI 42, 53 and 401 certifications. The difference is the cartridge itself — the internal keying, the seal and the flow path are built for different refrigerator families, so a Filter 1 will not lock into a Filter 2 housing.

The shortcut: look at the number printed on the filter you are pulling out. If it says "Filter 1" or W10295370A, you need EDR1RXD1. If it says "Filter 2" or W10413645A, you need EDR2RXD1.

What is the EveryDrop Filter 1 (EDR1RXD1)?

Filter 1 is the successor to the long-running W10295370A cartridge, which is why so many households still search for the old number. It is a purple-capped, twist-in filter that seats in the upper right corner inside the fresh food section.

Whirlpool-family model prefixes that commonly call for Filter 1 include Whirlpool WRS, WRF and WRX series, Maytag MFI, MFT and MSS series, KitchenAid KRFC, KRFF, KRSC and KRMF series, Amana ASD and ASI series, and Jenn-Air JFC models. Because the same filter spans side-by-side, French door and bottom-freezer layouts, you cannot judge by the shape of your fridge alone.

Inside, an activated carbon core handles chlorine taste and odour, sediment and lead, so the water coming out of the dispenser tastes like water again rather than like the tap. If your model calls for this one, you can buy the EDR1RXD1 replacement filter here with free shipping to all 50 states.

What is the EveryDrop Filter 2 (EDR2RXD1)?

Filter 2 replaces the W10413645A and a long list of superseded numbers including W10238154, W10413645, W10609378 and AP5983562. Kenmore owners often find it listed as 46-9902.

Physically it is the same twist-in style cartridge in the same top-right position, roughly 2 inches wide and 7.5 inches long. What differs is the fit: the housings in Filter 2 refrigerators are keyed for this cartridge, so a Filter 1 pushed into that slot will either refuse to lock or seat badly and leak.

Filtration-wise it is in the same class — a 0.5 micron carbon block certified under NSF/ANSI 42, 53 and 401 to reduce chlorine taste and odour, lead, cysts, pesticides and pharmaceutical traces. If your fridge takes this one, order the EDR2RXD1 water filter here.

The three differences that actually matter

1. Cartridge fit, not filtration quality

People assume Filter 2 is "the better one" because the number is higher. It is not an upgrade path. Both filters clean water to comparable standards; the number simply identifies which housing the cartridge was designed for.

2. The legacy part number

Most shoppers arrive here holding an old cartridge with a faded W10295370A or W10413645A on it. That number is the single most reliable identifier you have, and it maps cleanly: W10295370A goes to Filter 1, W10413645A goes to Filter 2.

3. Cross-brand names

The same cartridge is sold under Whirlpool, Maytag, KitchenAid, Amana, Jenn-Air and Kenmore numbers. Do not assume a Kenmore fridge needs a Kenmore-branded filter — many Kenmore units are built on Whirlpool platforms and take an EveryDrop cartridge.

How to find out which EveryDrop filter you need

Method 1: Read the old filter

Twist out the cartridge that is in there now and read the label. It will say Filter 1 or Filter 2, or carry the legacy part number. Thirty seconds, zero guesswork.

Method 2: Check the model number sticker

Your refrigerator model number lives on a sticker inside the fresh food compartment — usually on the left side wall, near the crisper drawers, or behind the bottom grille. Write down the full string, including letters and digits, and match it against the compatibility list on the product page.

Method 3: Check the manual or the filter door

Many Whirlpool-family refrigerators print the required filter number right on the filter housing door or the surrounding trim. The owner's manual water filter section lists it too.

Still unsure? Send us your model number and we will confirm the right cartridge before you order.

Can you use Filter 1 instead of Filter 2?

No. Even when a mismatched cartridge appears to twist in, the seal geometry is different, and the usual results are a filter that will not lock, water backing up behind the housing, or a slow drip down the inside of the door. Forcing a filter can also damage the housing, which is a far more expensive repair than simply buying the correct cartridge. Match the number and you avoid the whole problem.

Kenmore owners: how the cross-reference works

Kenmore is a retail brand, not a factory. Many Kenmore refrigerators were built on Whirlpool platforms, which is why a Kenmore fridge can happily take an EveryDrop cartridge. Kenmore numbers beginning 46- are the ones to watch: 46-9081 and 46-9930 line up with Filter 1, while 46-9902 lines up with Filter 2. If the sticker inside your fridge starts with 106., you are almost certainly on a Whirlpool-built unit and the EveryDrop cross-reference applies. When the numbers disagree with each other, trust the number printed on the cartridge you removed over anything printed on the box it came in years ago.

What it costs you to stretch a filter past six months

A saturated carbon block stops adsorbing and starts acting as a plain restrictor. Flow at the dispenser drops, the ice maker fills more slowly and produces smaller cubes, and the taste and odour reduction you paid for quietly disappears. In hard-water homes the cartridge can also become a trap for sediment, which is what turns a slow dispenser into a leaking one. Replacing on schedule costs a few cents a day and protects the dispenser and ice maker hardware behind it.

Price, shipping and replacement schedule

At FilterMatchPro the EDR1RXD1 sells for $38.99 and the EDR2RXD1 for $38.90, both single packs, with multi-pack options if you would rather stock a year ahead. Shipping is free to all 50 US states with no minimum, and every order is covered by a 30-day return policy.

Plan on a new cartridge every six months, or sooner if your household drinks a lot of dispensed water, if flow has slowed to a trickle, or if the taste has drifted back. Our guide on when to replace your refrigerator water filter covers the warning signs in more detail, and the five-step installation walkthrough takes you from unboxing to a purged, ready-to-drink dispenser.

Frequently asked questions

Is EDR1RXD1 the same as W10295370A?

Yes. EDR1RXD1 is the current EveryDrop name for the cartridge previously sold as W10295370A. They are direct replacements for one another.

Is EDR2RXD1 the same as W10413645A?

Yes. EDR2RXD1 supersedes W10413645A along with W10238154, W10413645 and W10609378.

How long does each filter last?

Roughly six months or 200 gallons, whichever comes first. Hard water and heavy dispenser use shorten that window.

Do I have to flush the filter after installing it?

Yes. Run about two to three gallons through the dispenser to clear trapped air and loose carbon fines. Cloudy or spitting water for the first few pours is normal.

Are compatible filters as good as the branded cartridge?

A well-made compatible filter tested to NSF/ANSI 42 and 53 performs comparably at a lower price. We cover the trade-offs in compatible vs OEM refrigerator water filters.

Why is my new filter leaking?

Nine times out of ten it is the wrong cartridge or one that was not twisted fully into the lock position. Confirm the number, reseat it, and check our filter troubleshooting guide.

Does the filter number affect ice maker performance?

Yes, indirectly. The ice maker draws through the same filter, so a clogged or mismatched cartridge shows up first as slow, hollow or undersized cubes.

Can I run my fridge without a filter?

Most Whirlpool-family models will dispense with a bypass plug installed, but the water is then unfiltered. Check your manual before removing the cartridge without a replacement on hand.

Ready to order the right one?

Check the number on your old cartridge, then grab the match: EveryDrop Filter 1 (EDR1RXD1) if it reads Filter 1 or W10295370A, or EveryDrop Filter 2 (EDR2RXD1) if it reads Filter 2 or W10413645A. Free US shipping, 30-day returns, and clean-tasting water back in about five minutes.
