Quick Answer: “Whirlpool water filter” actually covers two different supply chains wearing one logo. Refrigerator cartridges (everydrop by Whirlpool, Filters 1-4, all NSF/ANSI 42, 53, 401-certified, ~6 months / ~200 gallons) are built in-house by Whirlpool Corporation. The WHELJ1 whole-house system, WHAROS5 reverse osmosis unit, and WHED20 under-sink filter are made under license by Water Channel Partners, the same company behind the EcoPure brand — and the WHELJ1 in particular is certified for chlorine taste/odor only, not lead or PFAS, despite what “whole-house filtration” implies. Which Whirlpool product is right for you depends entirely on which of those two product lines you’re actually shopping.
Most searches for “Whirlpool water filter” are really looking for one of two very different things: a replacement cartridge for a Whirlpool-family refrigerator, or a whole-house/under-sink system carrying the Whirlpool name at Lowe’s or Home Depot. They don’t come from the same factory, don’t share engineering, and in the whole-house system’s case, don’t offer the same breadth of contaminant protection the everydrop cartridges do. Below is what each one actually is, what it’s certified for, and current prices.

1. everydrop Filter 1 (EDR1RXD1) — Best Overall Fridge Filter
everydrop by Whirlpool Filter 1 (EDR1RXD1)
- Whirlpool Corporation's own in-house cartridge, not a licensed third-party product — the everydrop sub-brand it's sold under launched in 2015 as a rebrand of Whirlpool's earlier fridge-filter line.
- NSF/ANSI 42, 53, and 401-certified, covering chlorine taste/odor plus lead and roughly two dozen other listed contaminants, with about 99% lead reduction in Whirlpool's own testing.
- Rated for 6 months or about 200 gallons — check the filter number printed on your old cartridge or use Whirlpool's online Filter Finder before ordering, since Filter 1 through 4 fit different fridge chassis rather than representing a good-better-best tier.

Filter 1 is the cartridge most Whirlpool, Maytag, and KitchenAid owners actually need, and it’s the same pick our best refrigerator water filter roundup lands on for the Whirlpool family. What that broader roundup doesn’t cover is the rest of the Whirlpool-branded filtration catalog, which is the point of this page.
2. everydrop Filter 2 (EDR2RXD1) — Best Broader Contaminant List
everydrop by Whirlpool Filter 2 (EDR2RXD1)
- Fits a different range of side-by-side models than Filter 1 — confirm fit against your fridge's filter housing before buying, since the two aren't interchangeable.
- Whirlpool's own spec sheet lists roughly 70 tested contaminants, including microplastics, versus about 24 for Filter 1 — same certification standards, broader tested list.
- Also sold rebadged as Kenmore's 46-9082 cartridge, a useful cross-reference if you're comparing prices across retailers under two different product names.
If your fridge takes Filter 2 rather than Filter 1, you’re not getting a downgrade — the housing determines which filter fits, and Filter 2’s tested-contaminant list is actually the longer of the two.
3. Whirlpool WHELJ1 — Best Whole-House (Chlorine/Taste Only)
Whirlpool WHELJ1 Central Water Filtration System
- Manufactured under license by Water Channel Partners, not built in-house by Whirlpool Corporation — the same company licenses the EcoPure brand, so mechanically similar systems exist under both names.
- No replaceable cartridge: a self-backwashing carbon media bed cleans itself roughly every 14 days, rated for about 10 years or up to 1,000,000 gallons before the unit itself needs replacing.
- NSF-certified for chlorine taste and odor reduction only — not lead, not PFAS, not heavy metals. Independent testing has measured chlorine reduction around 83% with a 40-micron sediment stage, coarser than the 1-micron filtration some rival whole-house systems use.
The “no filter to replace” pitch is real but easy to misread — you’re not replacing a cartridge, but the whole unit is rated to run down after roughly a decade, and its certification is genuinely narrower than the whole-house systems in our main best whole-house water filter guide, several of which are certified against lead, PFAS, or both.
4. Whirlpool WHAROS5 — Best Under-Sink Reverse Osmosis
Whirlpool WHAROS5 UltraEase Reverse Osmosis System
- Three-stage reverse osmosis marketed specifically against PFOA/PFOS ("forever chemicals") along with broader TDS reduction, via Water Channel Partners' "UltraEase" quarter-turn cartridge system that needs no tools or water shutoff to swap.
- Replacement parts are split into the WHEERF carbon pre/post-filter set (about 6-month life) and the WHEERM membrane (roughly 1-2 year life) — budget for both as separate consumables.
- Base-unit pricing varies widely across retailers and wasn't consistently verifiable at publication; confirm the current price at checkout before comparing it against our [best reverse osmosis system](/best/best-reverse-osmosis-system/) picks.
The PFOA/PFOS-focused marketing lines up with what reverse osmosis membranes generally do well, and the tool-free cartridge swap is a genuine convenience edge over screw-in RO housings — just don’t skip verifying the current price, since this is the one Whirlpool product in this roundup where retail listings weren’t consistent enough to quote a confident number.
5. Whirlpool WHED20 — Best Budget Under-Sink
Whirlpool WHED20 Dual Under-Sink Filtration System
- Dual-stage carbon filtration, NSF-certified against sediment, cysts, chlorine taste/odor, and lead — a simpler and cheaper alternative to the WHAROS5 RO system for households that don't need TDS reduction.
- Replacement filter (WHEEDF) runs about 6 months or 270 gallons, priced around $64-66 at major retailers — a helpful anchor even where the base unit's own price is inconsistent.
- Same UltraEase-style licensed-manufacturing lineage as the WHELJ1 and WHAROS5, via Water Channel Partners rather than Whirlpool Corporation directly.
This is the pick for anyone who wants NSF-certified lead reduction under the sink without paying for a full RO system’s membrane and drain-line install — a reasonable middle step between a pitcher and the WHAROS5.
The honest take: two Whirlpools, one logo
The single most useful thing to know before buying anything labeled “Whirlpool water filter” is that you’re choosing between two unrelated supply chains. The everydrop refrigerator cartridges are Whirlpool Corporation’s own product, backed by real NSF/ANSI 42/53/401 certification and a company that has aggressively sued counterfeit-filter sellers in federal court to protect that line. The whole-house and under-sink systems carry the same logo but are manufactured under license by Water Channel Partners — the same company behind the EcoPure brand — and at least one of them, the WHELJ1, is certified for meaningfully less than its “whole-house filtration” name implies. Neither fact makes the licensed products bad; it just means the Whirlpool badge isn’t a single, consistent promise the way it is on the fridge filters.
The bottom line
If you’re replacing a fridge cartridge, confirm your model against Whirlpool’s Filter Finder and buy the
matching everydrop Filter 1 ($50-65) or Filter 2 ($66) — both carry the same NSF/ANSI 42, 53, 401
certification Whirlpool backs with its own name. If you’re shopping whole-house or under-sink systems, know
that the WHELJ1 (~$420-450) only certifies against chlorine taste and odor, not lead or PFAS, while the
WHAROS5 RO system and WHED20 under-sink unit offer broader NSF-backed protection for households that
need it — just verify current pricing at checkout on those two. For deeper single-purpose picks, our
