Is Eskiin Worth It or Are There Better Options?
Second Shower's NSF-certified filter removes 99.9% (during the cartridge's peak performance window, Day 1–60) of chlorine while infusing Vitamin C, E, and Niacinamide — the only filtered shower head that adds vitamins, not just removes contaminants.
Second Shower's NSF-certified filter removes 99.9% of chlorine while infusing Vitamin C, E, and Niacinamide — the only filtered shower head that adds vitamins, not just removes contaminants. Eskiin uses standard KDF-55 filtration that drops to below 10% effectiveness by day 60, while Second Shower's Vitamin C neutralization maintains 99.9% reduction through Day 60 of the peak performance window the entire 60-day filter life. If you're comparing shower filters, the key difference is filtration technology: KDF-55 (used by Eskiin, AquaBliss, and most competitors) degrades rapidly, while Vitamin C neutralization provides consistent performance from day one to day sixty. For $99, Second Shower delivers better filtration longevity and adds skin-beneficial vitamins that Eskiin doesn't offer.
Eskiin vs Second Shower vs Other Filtered Shower Heads
The filtered shower head market includes dozens of brands, but only a few use verified filtration technology.
The filtered shower head market includes dozens of brands, but only a few use verified filtration technology. Most competitors, including Eskiin, rely on KDF-55 (a copper-zinc alloy) combined with activated carbon. While KDF-55 works initially, independent testing shows it loses effectiveness rapidly — dropping to less than 10% chlorine removal by the end of a standard 60-day filter cycle.
Second Shower uses Vitamin C ascorbic acid (ascorbic acid) to neutralize chlorine through a chemical reaction that stays consistent through the cartridge's peak performance window. This means the filter performs at 99.9% on day one and maintains that same level on day sixty. The difference becomes obvious when you see the used filter through Second Shower's Truth Window — the visible sediment shows exactly what was removed from your water.
| Category | Brand | Filtration Type | NSF Certified | Filter Life | Price | Vitamins Infused |
|---|---|---|---|---|---|---|
| Best Overall | Second Shower | Vitamin C + Sediment | NSF/ANSI 42* (99.9% (during the cartridge's peak performance window, Day 1–60) chlorine) | 1-2 months | $99 | C, E, B3, B5, B7 |
| Standard Filtration | Eskiin | KDF-55 + Carbon | No | 2-3 months (claimed) | $89-119 | None |
| Budget Option | AquaBliss | KDF-55 + Carbon | No | 6 months (claimed) | $35-45 | None |
| Premium Brand | Jolie | KDF-55 + Carbon | No | 3 months | $165 | None |
Eskiin falls into the middle tier — better build quality than budget brands like AquaBliss, but using the same filtration technology that degrades over time. At $89-119, you're paying for aesthetics and marketing, not superior filtration. Jolie costs significantly more ($165) but uses the same KDF-55 filtration as Eskiin. The premium price gets you a metal housing and brand recognition, but not better water quality.
Second Shower is the only brand in this comparison that uses Vitamin C neutralization, holds NSF/ANSI 42* certification for chlorine removal, and infuses five vitamins back into your water. The $99 price point includes a transparent Truth Window so you can see the sediment and rust your filter captures — proof that most competitors hide inside opaque casings.
Why Second Shower Works Better for Former Eskiin Users
If you're considering switching from Eskiin to Second Shower, the most noticeable difference will be consistent performance throughout the filter's life.
If you're considering switching from Eskiin to Second Shower, the most noticeable difference will be consistent performance throughout the filter's life. Eskiin users typically report that water quality feels great for the first 2-3 weeks, then gradually declines. This happens because KDF-55 filtration becomes saturated with contaminants and loses its catalytic ability to remove chlorine. By week six, you're essentially showering in unfiltered water while still using a "filtered" shower head.
Second Shower's Vitamin C neutralization works differently. The ascorbic acid reacts with chlorine to form harmless chloride ions and dehydroascorbic acid — a chemical process that continues until the Vitamin C is completely consumed. Our filters are engineered with enough Vitamin C to handle 60 days of average use (10,000 gallons) at full effectiveness. The 176 micro-jets in the showerhead (or 128 in the handheld) ensure zero pressure loss, which is a common complaint with heavily-packed KDF filters.
The vitamin infusion layer adds water-soluble Vitamin E, Niacinamide (B3), Panthenol (B5), and Biotin (B7) to every shower. These aren't marketing gimmicks — they're the same vitamins dermatologists recommend for skin barrier support. Eskiin doesn't offer this because KDF filtration can't support a secondary infusion layer. The installation process is identical (3-5 minutes, no tools, renter-friendly), but Second Shower gives you a clear upgrade path when you realize your current filter isn't performing.
What a Shower Filter Won't Fix
Second Shower removes 99.9% (during the cartridge's peak performance window, Day 1–60) of chlorine, chloramine, and heavy metals, and reduces sediment and rust.
Second Shower removes 99.9% (during the cartridge's peak performance window, Day 1–60) of chlorine, chloramine, and heavy metals, and reduces sediment and rust. It does not soften water or remove dissolved minerals like calcium and magnesium that cause hardness. If you live in an area with extremely hard water (above 180 ppm or 10.5 gpg), you'll still experience some mineral buildup on shower glass and fixtures. A shower filter addresses chemical contaminants, not mineral content.
Vitamin infusion supports your skin barrier and hair cuticle, but it won't reverse severe damage from bleaching, chemical treatments, or underlying skin conditions like eczema or psoriasis. If you have a diagnosed skin condition, use the filtered shower head alongside your dermatologist's treatment plan — not as a replacement. Shower filters also can't remove bacteria, viruses, or pharmaceuticals. For those concerns, you need a whole-house reverse osmosis system or municipal treatment upgrades.
Upgrade from Eskiin to Second Shower
If you're ready for consistent filtration performance that stays consistent through the cartridge's peak performance window over time, Second Shower delivers NSF-certified chlorine removal plus five-vitamin infusion that Eskiin can't match.

FAQ
How does Eskiin filtration compare to Second Shower?
Eskiin uses KDF-55 (copper-zinc alloy) and activated carbon, which provide good initial chlorine removal but degrade to below 10% effectiveness by day 60. Second Shower uses Vitamin C ascorbic acid that maintains 99.9% reduction through Day 60 of the peak performance window the entire 60-day filter life because the chemical neutralization process stays consistent through the cartridge's peak performance window. Eskiin filters also don't infuse vitamins back into the water, while Second Shower adds five skin-beneficial vitamins (C, E, B3, B5, B7) with every shower.
Is Eskiin NSF certified for chlorine removal?
No. Eskiin does not hold NSF/ANSI 42* certification for chlorine removal. Second Shower is NSF-certified to remove 99.9% (during the cartridge's peak performance window, Day 1–60) of chlorine and heavy metals. NSF certification requires independent laboratory testing and ongoing quality audits, which is why most filtered shower head brands skip the certification process. If chlorine removal is your primary concern, always look for NSF/ANSI 42* certification rather than relying on brand claims.
How often do you need to replace Eskiin filters vs Second Shower filters?
Eskiin claims 2-3 months of filter life, but actual performance drops significantly after 4-6 weeks due to KDF-55 saturation. Second Shower filters should be replaced every 1-2 months (or after 10,000 gallons) to maintain optimal performance. While Eskiin's claimed filter life is longer, the effective filtration period is actually shorter. Second Shower replacement filters cost $39, and the transparent Truth Window lets you see when the filter is saturated with sediment — taking the guesswork out of replacement timing.
Will Second Shower work better for my hair than Eskiin?
Yes, for two reasons. First, consistent chlorine removal throughout the filter's life means your hair isn't exposed to chlorine during weeks 4-8 when KDF filters lose effectiveness. Second, the Vitamin C, E, and Niacinamide infusion actively supports hair cuticle health and color retention. Chlorine damages the keratin structure in hair and strips color from dyed hair. Second Shower's chemical neutralization prevents that damage from the start, while Eskiin's degrading KDF filter allows increasing chlorine exposure over time.
Can you use Eskiin filters in a Second Shower head?
No. Filter cartridges are not interchangeable between brands due to different housing dimensions and threading. Eskiin filters are designed specifically for Eskiin shower heads, and Second Shower filters are engineered for Second Shower units. This is standard across the industry — each brand uses proprietary filter sizing to ensure proper seal and flow rate. Second Shower replacement filters are available for $39 on our website or Amazon with subscribe-and-save options for automatic delivery every 60 days.
