Vitamin C shower filters
Your shower water deserves
a second look.
Second Shower neutralizes chlorine and chloramine with Vitamin C, catches sediment, and puts the filter in view.
Chlorine or chloramine
Your city may not use
chlorine at all.
Your tap water may be treated with either. Second Shower's Vitamin C core neutralizes both.
- Free chlorine removed
- Fades on its own. Most cities use it.Independent third-party lab test, shower temperature.
- Chloramine
- Chlorine bonded to ammonia. Made to last in the pipes.Internal testing. Independent testing pending.
99.9%
Neutralized
More than one in five Americans use water treated with chloramine (US EPA).
The Truth Window
Look twice.
It’s in the window.
Both sit behind a clear window on the showerhead, so you can see the filter as you shower.
A micron PP layer, certified to NSF/ANSI 42, catches rust and sediment. It changes color as it collects particles.
Neutralizes chlorine and chloramine as the water passes, and slowly dissolves as it works.
Color changes show captured sediment, not chlorine or chloramine removal levels.

Top 10-ish: Emma Jade Morrison
I tried all the other filters ... none of the other filters I had tried removed that.
This does.
Name and quote approval for press use pending
Unpaid and unprompted. No sponsorship and no outreach from us.
Performance over time
Day 1 = Day 60
In our internal performance test, the filter performed the same on the last day of its recommended life as on the first.
Internal test. Replace every 60 days on the Showerhead and every 30 on the Showerhand.
Skin study
Skin, measured.
Two weeks of showers, measured with instruments.
22 women, two weeks, before-and-after study, no control group. Study observations, not a result for everyone.

Story ideas
Three ways into the story.
01Consumer, home and health, local news
Chlorine isn't the whole shower-water story.
Many US cities treat water with chloramine, which lasts longer in the pipes than chlorine. Second Shower is built to neutralize both.
02TV, video and social, design
A shower filter you can actually see.
A clear window on the front shows the filter as it works. Customers in 24 states have sent photos of theirs, labeled with the city and days of use.
03Beauty, skin and hair
What changed in a two-week skin study.
Twenty-two women showered with Second Shower for two weeks. Instruments recorded hydration up 26.7% and excess sebum down 69%.
