THE DAILY RITUAL

Two minutes today. Every morning after.

The whole point of Dulcis Agua is that it asks almost nothing of you. One fitting, then years of showers that are quietly better than they were.

FITTING

Unscrew,thread,done

Turn your existing shower head anticlockwise until it comes away in your hand. Thread the filter onto the bare arm, then thread the head back onto the filter. Hand-tight is tight enough — a wrench will only mark the chrome.

If either joint weeps, unscrew it and add one of the washers in the box.

THE FIRST SHOWER

Run itfor aminute

New media carries a little dust from packing. Let the water run for sixty seconds before you step in and it clears completely.

What you notice first is usually smell. Chlorine is the thing people stop registering until it is gone.

THE WEEKS AFTER

Skin stopsasking forlotion

The change is gradual and easy to miss while it is happening. Most people notice it backwards — a week away from home, a hotel shower, and the tightness returns.

Hair takes longer. Colour holding between salon visits is usually the first sign.

EVERY THREE MONTHS

One minute,four timesa year

Unscrew the housing by hand, lift the spent cartridge out, drop the new one in, screw it back. No tools, no plumber, no shutting off the water.
