The Vitamin C Shower Filter That Neutralizes Chlorine

43 grams of pure L-ascorbic acid per cartridge,
a number no other brand publishes.

Four scents. Watch it work.

It might not be your shampoo.

Municipal water is chlorinated to keep it safe to drink. That same chlorine strips the natural oils from your skin and hair every time you shower.

Dry, flaky skin that no moisturizer fixes. Hair that feels like straw. That faint pool smell in the bathroom. People spend years changing products before they check the water.

How It Works

  • Install

    Screw in your Pluvena cartridge. Under 30 seconds. No tools.

  • Shower

    Vitamin C neutralizes free chlorine on contact, converting it to harmless chloride.

  • Watch it work

    The coloured gel depletes as the vitamin C is used up. When it runs clear, refresh.

    43 grams. Not a percentage.

    Search this category and you'll find percentages everywhere. "99.9% removal." "98.7% of the bad stuff." Almost nobody publishes an absolute number.

    Percentages without conditions are close to meaningless. Independent labs have tested filters marketed at 98.7% chlorine removal and measured zero.

    A gram figure can be checked. Each Pluvena cartridge holds 43 grams of L-ascorbic acid, which neutralizes roughly 17 grams of free chlorine — about 7,200 litres of typical municipal water.

    We'd rather compete on a number that can be proven wrong.

      What Pluvena is, and isn't.

      Pluvena removes free chlorine. Completely, and we publish the maths.

      It does not soften hard water. It does not remove chloramine, heavy metals, or disinfection byproducts. Nothing that screws onto a shower arm does those things well.

      If your problem is limescale and chalky residue, you need a softener, not a filter. If it's dryness, itching, or that chemical smell — chlorine is a likely culprit, and this is built for exactly that.

      We'd rather you knew what you were buying.

            How long does one cartridge last?

            Each cartridge is rated for 7,200 litres which is about 120 showers at a typical
            8-minute shower. For one person showering daily, that's roughly 3–4 months.
            For two people, 1–2 months.

            If your water is heavily chlorinated, it will be less.

            Here's the math:
            Each cartridge holds 43 grams of L-ascorbic acid, which neutralizes about
            17 grams of free chlorine. At 2.4 ppm chlorine, that's 7,200 litres. At 4.0 ppm, the EPA's maximum, it's closer to 4,300 litres.

            The coloured gel visibly depletes, so you'll see when it's time to refresh.

            Yes. Pluvena is thoughtfully formulated with gentle, well-established ingredients. The rinse-off format means minimal skin contact time. If you have specific sensitivities, we recommend reviewing the full ingredient list on each product page.

            Pluvena's Vitamin C formula helps neutralize chlorine and chloramine. For heavy hard water with significant mineral buildup, you may benefit from an additional inline water softener alongside Pluvena.

            Simply unscrew your existing showerhead, screw on the Pluvena head, and screw in your first cartridge. No tools needed, takes under 30 seconds.

            Yes. Every Pluvena comes with a 60-day satisfaction guarantee. If you're not completely happy, we'll make it right. Contact hello@pluvena.com.

            Each cartridge contains a colored gel that gradually depletes as you shower. When the gel is nearly gone, it's time to refresh with a new cartridge. No apps, no reminders, just look at it.

            Traditional shower filters focus solely on filtration. Pluvena combines filtration with skincare-inspired ingredients like Vitamin C, Vitamin E, and Hyaluronic Acid, designed to elevate your daily ritual.
