Product Details

Water changes character long before it reaches your skin. In hard-water regions, chlorine and sediment build up in the line and over time, that's what your shower is actually rinsing you in. The Renewal Cartridge is the internal core that does the work inside every Dulcis Agua filter: a multi-stage media bed that reduces chlorine, fine sediment, and trace heavy metals before the water ever reaches you.

It's built to be replaced, not maintained a quiet, three-minute act of upkeep rather than a chore. Twist out the spent cartridge, twist in the new one, and the filter is renewed.

Why replace it regularly
Filtration media has a working life. As it saturates, its ability to reduce chlorine and sediment declines — the water still flows, but it's no longer doing what it should. Replacing the cartridge on schedule is what keeps the filter's performance consistent, not just its appearance.

What it's built for
Compatible with the Dulcis Agua Shower Filter and Duo Filtered Shower System, and sized to fit most standard inline shower filter housings.

5. Key Features & Benefits

7. Variant Options

Supplier lists four cartridge finishes: Silver, Gold, Nickel, Bronze.

Recommend confirming with the supplier whether these are:
(a) purely cosmetic media-color variants with identical filtration performance, or
(b) genuinely different media compositions/stage counts.

If (a): list as a single SKU with a "finish" swatch selector.
If (b): list as separate SKUs with distinct spec callouts, since performance claims would need to differ per variant do not present them as interchangeable if the media differs.

Care


Handle the cartridge by its collar rather than the media core when installing or removing it.

If scale builds up in hard-water conditions, rinse the housing with warm water avoid abrasive cleaners or solvents, which can affect the chrome finish over time.

Store spare cartridges in a cool, dry place away from direct sunlight until you're ready to install them.

Replace on schedule rather than by appearance. Filtration performance declines before any change is visible in the water.

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.
