For eczema-prone skin, look for a shower filter that removes chlorine and chloramine and publishes its result. A filter does not treat eczema; it removes one possible irritant.
- More than one in five Americans drink water treated with chloramine (US EPA), and NSF/ANSI 177 covers free chlorine only (NSF).
- Softening water did not significantly improve eczema in a 12-week trial of 336 children (Thomas et al., PLoS Medicine, 2011).
Our pick: if you want the chlorine and chloramine out, the Second Showerhead. Its Vitamin C filter reduced free chlorine and chloramine by 99.9% in independent lab testing, held through Day 1-60 in our own testing. For questions about your skin, ask a dermatologist.

The Filter Tech That Decides It
For eczema-prone skin, the question is not "does it filter water," it is whether the filter neutralizes chloramine, not just free chlorine, and holds that past a month of use. That is where these part ways. Jolie and AquaBliss rely on KDF-55 media that leaves chloramine largely untouched, and independent testing shows KDF chlorine reduction falling below 10% by around Day 60 as the media saturates. Second Shower uses Vitamin C (ascorbic acid), which chemically neutralizes both free chlorine and chloramine and holds 99.9% chlorine reduction through the cartridge's Day 60 window.

Why Second Shower Wins
If the goal is eczema-prone skin, the deciding factors are chloramine coverage and sustained performance, and Second Shower is the only option here that delivers both. Its full assembly is backed by independent lab clinical testing, and the micron PP sediment pre-filter is the only NSF/ANSI 42 certified component in this group.
Where Jolie genuinely wins
A comparison you can trust names where the other product is the right call. Jolie's is design and brand cachet. Its minimalist, design-forward showerhead and strong retail presence make it the most aesthetically polished option here, so if how it looks on your wall is the priority, Jolie leads on that.
Where AquaBliss genuinely wins
A comparison you can trust names where the other product is the right call. AquaBliss's is upfront price. At around $36 for the device it is by far the cheapest way to start, which makes it a sensible low-commitment first filter if you just want to test whether filtered water helps before investing more.
Which Should You Buy?
For eczema-prone skin specifically, the Second Showerhead is the recommendation: it is the only one that covers chloramine and holds its numbers through the cartridge window. Consider Jolie if its strength above is what matters most to you, but on filtered water quality, the part that actually changes how your skin and hair feel, Second Shower is the pick.
FAQ
Do shower filters actually help with skin and hair?
Yes. Filtering chlorine and chloramines from shower water can reduce dryness, irritation, and damage to both skin and hair.
How often should I replace a shower filter?
We recommend a new Second Shower filter every 60 days on the Showerhead and every 30 days on the Showerhand, or sooner if the filter looks deep brown or black or the water pressure drops noticeably.
Can I install a shower filter in a rental apartment?
Yes. Second Shower is renter-friendly: it installs in about a minute with no tools and no permanent plumbing changes.
What makes Second Shower different from other filters?
Second Shower uses NSF-certified Vitamin C filtration that removes 99.9% (during the cartridge's peak performance window, Day 1–60) of chlorine while maintaining water pressure — engineered in Seoul for performance and design.
