The case for filtration
What unfiltered water leaves behind
Before it ever touches a bottle in your routine, your water has already gone to work on your skin and hair.
Pulls moisture from skin and hair, leaving both tight, dry and easily irritated
Leaves a dulling mineral film that flattens shine and weighs hair down
Wears down the protein bonds that give hair its natural strength
Fades color-treated hair a little more with every rinse
Can aggravate sensitive skin — tightness, redness, occasional breakouts
Adds to the oxidative load linked to early signs of skin aging
Which is why we reduce it first, not after.
The story behind
Long before the first fixture takes shape, we start with the water itself measuring hardness, chlorine, and mineral load in every market we sell into. What survives ninety days of daily use, undiminished, is what earns the Dulcis Agua name.
Everything we make
One filter, the cartridges that keep it running, and nothing else.
