Even the best water on earth went through a pipe first.
Iceland's tap water is some of the cleanest on the planet. It still runs through metal that's been in the ground for decades. A good source doesn't buy you a clean delivery.

Rust and sediment don't come from the reservoir, they come from the last few meters of pipe, wherever that pipe is.

Hard water minerals build up regardless of what the label on the water report says.

Chlorine is added on purpose to make water safe to pipe. That's exactly why it's still in there when it reaches you.
Different city,
different gunk.
Same reason
to filter it.
Three beads. Swap for wherever you are.
Every filter runs the same base, 15g of calcium sulfite. What changes is the second scoop, swapped depending on what's actually coming out of the wall.
Pick the mode for your next trip, the shower head itself is sold separately.
City Skincare Module
Calcium sulfite plus vitamin C. Cuts chlorine at the source instead of just carrying it to your skin. Less dry scalp, less itch, hair colour that holds instead of fading in the shower.
Built for Hong Kong, Macau, Taiwan, Japan, South Korea, Singapore, USA, Canada, UAE.
Hard Water & Heavy Metal Defense
Calcium sulfite plus KDF55. Goes after the calcium and magnesium that make water feel hard and hair feel stiff, pulls out trace heavy metals, stays antibacterial the whole time.
Built for the UK, France, Germany, Italy, Spain, Australia, New Zealand.
Deep-Zone Purification Module
Calcium sulfite plus activated carbon. The carbon grabs onto the earthy smell, the rust smell, whatever's floating in water you don't fully trust.
Built for Indonesia, Thailand, Vietnam, the Philippines, India, and anywhere the pipes are older than the building.

PACK IT, FORGET IT'S THERE
比您的化妝包還要輕巧
Three modes, each built for a different kind of water. Pack the one that fits the trip, swap it when you fly somewhere new.
- Fits the Aurajex Triple Defense Travel Shower Filter
- Swap when the cotton turns dark brown
- Mix modes across a trip, swap when you change destination
- Restock before you pack, no need to reorder the whole kit

Dark means done
The cotton inside starts white. After a few days in unfamiliar water it won't be. Dark enough, swap it.
Quick habit: run the water 5 seconds before every shower, 15 seconds after you swap in a fresh cartridge.
