In Canton of Appenzell Innerrhoden, hard water causes limescale buildup in pipes and appliances. The Aquavital magnet protects households in Appenzell and across the region.
From CHF 930 one-time – no recurring costs
Watch the 2-minute videoLimescale builds up everywhere – on taps, in pipes and on your appliances. You feel the consequences every day.
Limescale marks on taps, tiles and shower walls – despite regular cleaning, they keep coming back.
Kettles, coffee machines and washing machines scale up and need to be replaced sooner.
Harsh cleaning products and constant scrubbing – limescale costs you valuable time.
Conventional softening systems remove valuable calcium and magnesium – and cause recurring costs.
Physically changes the limescale structure so that deposits are significantly reduced. No descaling – but intelligent limescale protection.
Purely physical effect through magnetic fields. No operating costs, no salt, no environmental impact.
Waterproof, frost-resistant and shockproof. 10 permanent magnets with 1.2 Tesla each – for lasting, reliable protection.
Simply attach to the water pipe without tools. No plumber needed – you can do it yourself.
No waste, no wastewater, no resource depletion. Environmentally friendly without compromise.
Calcium and magnesium remain fully in the water. No softening – only the limescale structure is changed.
No salt, no electricity, no filter changes. Simply remove briefly every 6 months – that's it. No operating costs.
Limescale marks wipe away easily with a damp cloth – without harsh cleaners. A noticeable time saver in everyday life.
Less limescale buildup in the boiler, kettle and washing machine reduces repairs and extends the lifespan of your appliances.
Just 1mm of limescale on the heating element increases energy consumption by up to 10%. Less limescale means lower electricity bills.
No descaling – but intelligent structural change through magnetic force.

Rough, needle-shaped limescale crystals that strongly adhere to surfaces and pipes.

Rounded, harmless crystals that no longer adhere to surfaces.
See how the sharp, adhesive limescale crystals are rounded and reduced by the magnetic fields.
Calcium hydrogen carbonate Ca(HCO₃)₂ is a dipole molecule – it has a positive and negative charge. This polarity causes the molecules to clump into larger clusters that deposit as limescale.
The 10 permanent magnets of the Aquavital (1.2 Tesla each) generate alternating magnetic fields that gradually break apart these clusters. The molecules remain individually dissolved in the water – deposits are significantly reduced.

Magnetic fields change the limescale structure – crystals become round and lose their adhesion.
Significantly less limescale buildup – appliances protected, cleaning made easier, minerals preserved.

The Kalkmagnet works on plastic, aluminium composite, iron and copper pipes. Simply attach – done.

Simple tests to see the difference for yourself within the first few weeks.
Tip: Before testing, remove existing limescale from taps and aerators. Over the next 30 days, some deposits will form – but they will be easy to remove.
Boil water in the kettle or an enamel pot. The limescale residue should be powdery and easy to remove with water and a household sponge, without cleaning products.
Spray a cleaned tile daily with the shower head. After more than a week, the dry residue can be easily removed with a damp cloth and a little neutral cleaner.
Reduce laundry detergent and dishwashing liquid by about 30–50%. Laundry feels noticeably softer after several washes. Chemical descalers become completely unnecessary.
Pay attention to your skin and hair after showering. With less shampoo, hair feels noticeably softer. People with sensitive skin report less itching and redness.
The Kalkmagnet does not remove limescale from the water – it changes the limescale structure. Through powerful magnetic fields, the limescale crystals are rounded so that they no longer adhere to surfaces and pipes. All valuable minerals are fully preserved.
No. Aquavital is deliberately not a softening system. The limescale content of the water stays the same – only the crystal structure is changed. That is the decisive advantage: you keep healthy, mineral-rich drinking water while having significantly fewer limescale problems.
Technically no: a water softener (ion exchanger) removes limescale from the water using salt and swaps calcium and magnesium ions for sodium. The limescale magnet works completely differently – it removes no limescale and needs no salt; it only changes the crystal structure so the limescale adheres far less. So it is not a softener but the salt-free physical alternative: the minerals stay fully in the water, with no recurring salt costs and no waste water.
Simply attach it to the water pipe – no tools and no professional needed. Installation takes less than 5 minutes. The Kalkmagnet works on plastic, aluminium composite, iron and copper pipes.
No. The Kalkmagnet works entirely without electricity, without chemicals and without salt. It uses exclusively permanent magnetic fields. This means: zero recurring costs and zero environmental impact.
Many customers report noticeable improvements after just a few days. Existing deposits gradually dissolve. The full effect develops within the first 2–4 weeks.
The warranty covers material and function. The Kalkmagnet has no wearing parts, is waterproof, frost-resistant and shockproof. In case of a defect, the device is replaced free of charge within one week.
Fill out the form – we take care of the rest. Your trial package is shipped free of charge within 3–5 business days within Switzerland. You test for 30 days with no purchase obligation. Not convinced? Free return shipping – you receive a return label, that's it. No fine print, no hidden costs, no purchase obligation. After purchase, the 90-day money-back guarantee also applies.
Minimal: We recommend removing the Kalkmagnet from the pipe for 24 hours twice a year. This allows magnetic particles (mainly iron) that have accumulated over time to detach. Then simply reattach – that's it. No tools, no professional needed.
Yes, normal cleaning is still necessary. However: limescale deposits are significantly reduced and much easier to remove. This saves time and you need fewer harsh cleaning products.

Limescale stays in the water: Aquavital changes the limescale structure but does not remove it. Hardness tests before and after installation therefore show the same result. The effect is seen in reduced deposits, not in changed measurement values.
Adjust dosage: After installation, reduce the amount of dishwashing and laundry detergent. Due to the reduced surface tension and changed limescale structure, you only need the amounts recommended for softer water.
Discolouration after installation: Slight reddish-brown discolouration of the water may occur temporarily. This is normal and one of the signs confirming the Kalkmagnet's effectiveness.
Correct installation: Proper function is only guaranteed if the installation and maintenance instructions are followed carefully. Pipe dimensions must match the device dimensions. Arrows must point in the direction of flow.
Maintenance: Remove the Kalkmagnet from the pipe for 24 hours twice a year so that accumulated magnetic particles can detach.
Scientific note: Although our long-standing experience and over 140'000 satisfied customers confirm the effectiveness, we transparently note that some of the methods used are discussed in certain circles of conventional science. 13 peer-reviewed studies and the expert report from the Hagalis Institute confirm the effectiveness.
