About Gillian
Metal on the outside. Beauty on the inside.
Gillian™ by HammerHead® was created to make every shower feel better — not just cleaner, but elevated. From the first touch, its solid metal weight and balanced flow remind you what real quality feels like. Inside, advanced filtration transforms ordinary water into something that’s gentler on your skin, kinder to your hair, and better for your everyday routine.
Filtration That Lasts
We built Gillian’s filtration around better media — and more of it. Using genuine KDF55® from Kymera (the only true KDF), paired with calcium sulfite, Gillian delivers longer-lasting, third-party tested filtration.
What sets it apart:
- Genuine KDF55® sourced directly from Kymera — not imitation media
- The most filtration media in its class (360g KDF55® + 55g calcium sulfite)
- Third-party tested under NSF/ANSI 177 for verified chlorine reduction
- Maintains performance over time, not just out of the box
