Vitamin C shower filter. You’ve seen the ads. It sounds fancy. But what is it, and does it actually work?
We’re Zooshen — we make shower filters. What we’ll tell you is the honest version: vitamin C media works, but it’s different from KDF-55.
The Quick Answer
| Question | Honest Answer |
|---|---|
| What is it? | A filter using ascorbic acid (vitamin C) media. |
| What does it remove? | Both chlorine and chloramine. |
| How does it work? | Chemical neutralization. Vitamin C reacts with chlorine. |
| How long does it last? | 2-3 months. Less than KDF-55. |
| Who is it for? | People with chloramine. |
What Is Vitamin C Media?
Vitamin C media is made from ascorbic acid (the same vitamin C you take as a supplement). When water flows through it:
- Vitamin C reacts chemically with chlorine and chloramine
- Converts them into harmless compounds (chloride ions)
- Gentle on skin and hair — no harsh chemicals
That’s it. Simple chemistry.
The Science: How It Works
The Chemical Reaction:
Ascorbic acid (vitamin C) + chlorine → dehydroascorbic acid + chloride ions
It’s a neutralization reaction. The vitamin C “absorbs” the chlorine, converting it into something harmless.
Why It Removes Chloramine:
KDF-55 only works on free chlorine. Vitamin C works on both free chlorine and chloramine. That’s the big advantage.
