THE PROBLEM
What hard water does to you – every day
Hard water contains high concentrations of limescale (calcium carbonate), magnesium, and often chlorine. That sounds abstract – but the effects are very concrete.
Brittle, dull hair
Limescale and chlorine build up on the hair structure, weighing down the hair and robbing it of shine and bounce. Hair care products are of little help – the problem lies in the water.
Dry, irritated skin
Chlorine attacks the skin's natural protective barrier. The result: dryness, tightness, and for sensitive skin, often redness or itching after showering.
Limescale everywhere
On glass showers, fixtures, and tiles, limescale appears as a white, cloudy film. Hard to remove, quick to return – an endless battle.
Clogged nozzles & loss of pressure
Limescale builds up in the showerhead nozzles, noticeably reducing water pressure over time. The showerhead clogs – the showering experience deteriorates.

How hard is the water in my area?
Particularly affected regions include Munich, Cologne, Frankfurt, Stuttgart, Hamburg, and Berlin – but a large part of the rural areas in Bavaria, Baden-Württemberg, and North Rhine-Westphalia also have very hard tap water. You can inquire about the water hardness in your region with your local water supplier.

FREQUENTLY ASKED QUESTIONS
Questions about hard water & the Aia Pure filter
How do I know if I have hard water?
The simplest signs: limescale spots on glass panes, fittings or kettles, soap that lathers poorly, or hair that feels dull and heavy after washing. You can find out the exact hardness value from your local water supplier or via corresponding online maps for Germany.
Is the Aia Pure shower head an alternative to a water softener system?
For shower water, yes – and at a fraction of the cost. Water softening systems cost several hundred to thousands of euros and must be installed by specialists. The Aia Pure shower head filters limescale, chlorine, and heavy metals directly at the shower head, without modification, for €39.90.
How often does the filter need to be changed?
We recommend changing it every 2–3 months, depending on the lime content of your water and how many people shower in your household. In regions with very hard water, it's better to change every 2 months; with medium water hardness, 3 months is sufficient. Replacement filters are available in a convenient pack of 2 for €19.90.
Does the filter reduce the water pressure?
No – on the contrary. Thanks to the precision nozzles of the Aia Pure showerhead, the spray is often perceived as more powerful than with conventional showerheads, even with low line pressure.
Which hoses does the shower head fit?
The Aia Pure shower head fits all commercially available standard shower hoses (G1/2" thread), which are installed in almost all households in Germany. Installation without tools is possible in about 2 minutes.
