We put it on before bringing the baby home. Two weeks later the inside was brown, which was honestly kind of gross.

Wasn't totally sold at first. Then I opened it up after a couple weeks and yeah, it was not clean.

Tampa water looks clear out of the tap, so I wasn't expecting much. The filter turned brown way faster than I thought.

My arms usually get itchy after hot showers. It's not gone, but the flare-ups have been way calmer lately.

My husband thought it was one of my random bathroom things. Then he saw the filter after a month and stopped joking.

We're on our third filter now. Every time I swap it, I'm surprised all over again by how dirty it gets.

Before, [the chlorine] was literally the levels of the swimming pool.

Built to remove what most shower filters miss.
Most filtered showerheads don’t address chloramine. Ours removes 99.9% of it, along with 99.9% of chlorine, in independent lab testing.
A reaction, not a trap.
Food-grade Vitamin C reacts directly with chlorine and chloramine, neutralizing both. A proprietary gel matrix protects it from oxidation before use.
The US EPA calls ascorbic acid, a form of Vitamin C, “an established and recognized dechlorinating agent.”
See how it worksRust and sediment stop here.
An NSF/ANSI 42 certified 5 micron sediment filter catches rust and sediment. The clear window shows what it captures.
NSF/ANSI 42 certification applies to this filter, not the complete showerhand.

Made in Korea. Measured independently.
The Korean team has focused only on shower and water filtration for over 14 years. In independent third-party lab testing, neither chlorine nor chloramine was detected after filtering 100 liters of tap water.
Independent laboratory result under test conditions. Not a measurement of the water in your home.

Reviews
Why they look twice
Real customers, sharing their experiences.
In Korea, showering outside the hotel, my skin got red and sensitive again. Back home in the US, it got better again. I’ll have to use this for the rest of my life.
I spent a year trying all these different dermatologists and being prescribed different creams to fix the issue, nothing was working. I started using this filter and it changed everything, my skin is clearer, it feels softer.
My husband thought it was one of my random bathroom things. Then he saw the filter after a month and stopped joking.
I also tested with one of those strips before and after. The chlorine didn’t show up anymore. And before it was literally the levels of the swimming pool.
My curly hair is looking the best it has in a very long time. Frizz was reduced tremendously! No other changes were made, other than the shower head.
My place always had low water pressure and the water just trickled out, but after installing this, the water pressure improved noticeably to a normal level.
You have questions. We like that.
Which device does this fit?
This Filter fits only the Showerhand. The Showerhand and the Showerhead use different filter sizes, so their Filters are not interchangeable.
Check your fitWhen do I replace the filter?
Replace it every 30 days, even if it looks fine. A 3-pack lasts about three months. Replace it sooner if it turns deep brown or black, or if water pressure drops.
How do I swap it?
Twist the handle end counterclockwise to detach it. Place the micron end up and the Vitamin C gel end down, then twist clockwise to reattach. If water does not come through, turn the Filter around. See the guide below.
Filter guideDark in a week. Is that normal?
Yes. Brown or dark color is sediment and rust the Filter caught, not mold. Faster darkening often means more sediment and rust, especially with older pipes. Color does not test chlorine or show remaining life. Much sooner than expected? Email a photo to hello@secondshower.us.
Do I have to subscribe?
No. A one-time 3-pack is $29; a plan is $27 with shipping included every 12, 16 or 20 weeks. One-time shipping is $6.99 below $40 and free at $40 or more. Skip, pause or cancel anytime, with no fees.
Can I return filters?
Yes. Unopened, unused Filters can be returned within 30 days of delivery. For a change of mind, you pay return postage. For a product or delivery problem, we provide a prepaid label.
ReturnsWill it soften hard water?
No. Shower filters, including ours, do not remove calcium and magnesium. That takes a whole-house softener.
