Eskiin vs Jolie
The two highest-demand brands in the category, built on the same two media, priced within twenty dollars of each other, and both describing a standard neither product holds. The tiebreaker is disclosure.
Disclosure — some links on this page go to Amazon, and we earn a commission if you buy through them. It costs you nothing extra and it does not change what we recommend or in what order. The full disclosure.
Both are replacement shower heads built on KDF-55 and calcium sulfite, and neither holds a certification. Jolie publishes a 1.8 GPM flow rate and a 90-day cartridge cadence; eskiin publishes neither. Neither has an independent chlorine measurement. On the evidence available, Jolie is the more checkable product.

Jolie Filtered Showerhead
The best-known name in the category
The most searched shower filter in the United States, with a media pairing that makes sense and a certification line that does not. "Surpassing NSF-177 certifications" is a claim about exceeding a standard the product is not stated to hold.

What it does well
- Media named outright: KDF-55 and calcium sulfite
- 1.8 GPM, compliant with California and New York flow limits
- 90-day cartridge cadence on subscription, so replacement actually happens
- Replaces the shower head, so there is nothing extra hanging off the arm
Where it falls short
- "Surpassing NSF-177 certifications" is a claim, not a certification
- No gallon capacity published, so cost per gallon cannot be computed from its own data
- Nothing published about chloramine
What it does not do
- It does not soften water. KDF-55 and calcium sulfite do not remove calcium or magnesium.
- It does not hold a stated NSF/ANSI 177 certification; the published wording is that it surpasses NSF-177 certifications.
- It does not treat hair loss. Reduced shedding and reduced breakage are different claims from androgenetic hair loss — see the hair-loss evidence page.
Who it is for
A reader who wants the well-known unit, a 1.8 GPM head that meets state flow limits, and a subscription that removes the decision about when to change the cartridge.
Skip it if
You want a verifiable certification rather than a testing claim, or you want a published gallon capacity you can do arithmetic with.

eskiin Filtered Showerhead
The highest-volume brand search
Sells more search interest than almost anything else in the category and publishes a media list that reads well. Its certification wording — tested to far exceed NSF-177 — is the same construction Jolie uses, and it means the same thing: not certified.

What it does well
- Media stated: KDF-55 and calcium sulfite with coconut activated carbon
- The single highest-volume brand term in this category
- Direct-sold, so cartridge supply is not dependent on a marketplace seller
Where it falls short
- "Far exceed NSF-177 certifications" is a claim, not a certification
- No canonical Amazon detail page we could verify
- No published flow rate, gallon capacity or chloramine figure we could retrieve
What it does not do
- It does not soften water. KDF-55 with calcium sulfite and carbon does not remove hardness minerals.
- It does not hold a stated NSF/ANSI 177 certification; the published wording is that it exceeds NSF-177.
- We could not confirm a canonical Amazon listing for it, so the buy link below is a search rather than a product page.
Who it is for
A reader who arrived searching the brand by name and wants the media pairing stated before deciding.
Skip it if
You want to buy it on Amazon with confidence in the listing, or you want a certification you can look up. eskiin sells mainly direct, and we could not confirm a canonical Amazon detail page.

Side by side
Both media lists are the makers' own. We have tested neither product, and neither appears in any independent bench test we could locate.
The same sentence, twice
Read the two certification lines next to each other and the resemblance is hard to miss. Jolie's media is described as "surpassing NSF-177 certifications". eskiin's is "proven to far exceed NSF-177 certifications". Both sentences position the product relative to a standard neither is stated to hold.
That construction is not illegal, and it is not necessarily untrue — both companies may well hold lab data showing exactly what they say. But it is doing different work from "tested and certified by IAPMO R&T", which is a claim about an accredited body issuing a mark and maintaining a public listing you can check. One is a statement about test results the manufacturer commissioned; the other is an ongoing obligation to somebody else. The full explanation of the difference, and which filters actually hold a listing.
What Jolie publishes that eskiin does not
Two numbers, and they are the two that matter for living with the thing. Jolie states 1.8 GPM, which is a figure you can check against your state's fixture cap and against the pressure you currently have. It also states a 90-day cartridge cadence, which is the input to any honest cost calculation.
eskiin publishes neither. Without a flow rate you cannot predict what the head will do to a shower that is already weak, and without a cadence you cannot work out what the filter costs to run past the purchase price. For a product at this end of the market, those are strange things to leave out. The cost arithmetic is only possible for one of these two.
Where eskiin edges ahead
Its media list is longer and more specific: KDF-55 and calcium sulfite plus coconut activated carbon. Carbon adds a mechanism the other two media do not have, and in principle it broadens what the cartridge can address beyond free chlorine. In practice the shower contact time of roughly a tenth of a second limits how much carbon can do, which is the constraint every filter in this category runs into.
So it is a real difference on paper and an unquantified one in the shower. Neither company has published a reduction percentage we can check, and neither product appears in an independent bench test.
Neither one softens water
Both are marketed into hard-water language. Neither performs ion exchange, and independent testing of this category found no filter that reduced hardness at all. If scale on the glass and poor lather are your actual complaint, both of these are the wrong purchase and the reason is mechanical rather than a quality problem.
The verdict
- Buy Jolie if you want the better-documented of the two — a published flow rate and a published cadence mean you can check it against your plumbing and your budget before you buy.
- Buy eskiin if the longer media list, including activated carbon, is what you are after and you are content to take the flow rate on trust.
- Buy neither if you want a certification. Neither holds one — the Culligan HSH-C135 and the Sprite Slim-Line 2 do.
- Buy neither if your utility uses chloramine. KDF-55 does not break the chlorine-ammonia bond, and neither product claims it does. What to buy instead.
- Buy neither for hard water. Neither softens, and nothing in this category does.
What we would skip, and why
Questions people actually ask
+ Is eskiin better than Jolie?
Not on anything we can verify. They use the same two core media, neither holds a certification, and neither has an independent chlorine measurement. Jolie publishes a flow rate and a cartridge cadence; eskiin publishes neither, which makes Jolie the easier product to check before buying.
+ Are eskiin or Jolie NSF certified?
Neither. Both describe their media as exceeding or surpassing NSF-177, which is a statement about a standard rather than a certification to it. The filters that actually hold a listing.
+ Do eskiin or Jolie remove chloramine?
Neither claims to, and KDF-55 does not break the chlorine-ammonia bond in chloramine. About one in five US systems uses chloramine, so check your utility report first.
+ Does eskiin or Jolie soften hard water?
Neither, despite both being marketed into hard-water language. No shower filter softens water — the contact time is around a tenth of a second and ion exchange needs seconds.
