I always thought our water was pretty good. Three weeks later the filter looked like that, so I guess not.

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

Chicago water always felt harsh, but seeing the filter after 40 days made it feel very real. My skin feels less dry too.

A small change. An ongoing routine.
Start with your water.
Install your shower filter and check the connection for leaks. Vitamin C reacts with chlorine; the sediment sleeve catches particles.
What the study measured.
In a two-week study of 22 women, measured facial skin hydration increased 26.71%. There was no control group. Individual results vary.
Keep the window in view.
Your filter may change colour as it collects sediment. Colour is not a measurement of chlorine removal or remaining filter life.
Keep the routine going.
Follow the replacement guidance for your model and local water conditions. Change sooner when needed; do not rely on colour alone.

You have questions. We like that.
What does Vitamin C do in a shower filter?
Vitamin C neutralizes chlorine and chloramine in shower water. A separate sediment sleeve catches particles such as rust. Each stage has a different job.
See how filtration worksWhat does the clear window show?
The window lets you see the sediment filter and the particles it collects. Its colour does not measure chlorine or chloramine levels, so follow the replacement schedule for your model.
See real filter recordsWill it soften hard water?
No. Second Shower treats chlorine and chloramine and filters sediment. It does not remove dissolved hard-water minerals such as calcium and magnesium.
Explore filtration detailsWhich model fits my shower?
Choose the Showerhead for a fixed wall-mounted setup, or the Showerhand for a handheld setup. Check your connection and the included parts in the model-specific installation guide before choosing.
Check the installation guideHow often do I replace the filter?
Replace the Showerhead filter every 60 days and the Showerhand filter every 30 days. Water conditions and use can mean replacing sooner. Choose the refill made for your model.
