What's in your water

Your shower water isn't as gentle as it looks.

Tap water is treated to be safe to drink, not to be kind to your skin and hair. Every day, the same things land on you in the shower.

01

Chlorine

Added to keep tap water safe, chlorine can leave skin feeling tight and hair dry and brittle.

02

Hard-water minerals

Calcium and magnesium leave a film on skin and hair, so it feels squeaky, dull and harder to style.

03

Sediment & rust

Older pipes can add fine particles and a metallic smell you only notice once it's gone.

Inside the cartridge

20 layers. One quiet upgrade.

Water passes through every layer before it reaches you. Scroll to see what each one does.

Layer01

  1. Stainless steel mesh

    First line of defense. Catches sand, scale and gritty sediment.

  2. PP cotton

    Traps fine debris so the water coming through is visibly clearer.

  3. KDF-55

    A copper-zinc media that helps reduce chlorine and heavy metals.

  4. Activated carbon

    Absorbs impurities and odors for fresher-smelling water.

  5. Calcium sulfite

    Neutralizes chlorine fast, even in hot water, to protect skin and hair.

  6. Vitamin C beads

    Removes residual chlorine while leaving water gentle on skin.

  7. Antibacterial beads

    Help keep the cartridge itself clean between showers.

  8. Far-infrared ceramic

    Mineral ceramic beads for water that feels softer on skin.

  9. Tourmaline & negative-ion beads

    Mineral layers chosen for a smoother, more comfortable shower.

  10. Maifan stone & limonite

    Natural mineral stones that finish the water before it reaches you.

Replace the cartridge every 6–12 months for best results.
