Perhaps Germany's best-known solution against limescale caused by hard water.

Die vielleicht bekannteste Lösung Deutschlands bei Kalk im Wasser

Lime in tap water: The problem faced by millions of homes.

Lime in tap water consists of the minerals calcium and magnesium. And this is not uncommon: In Germany alone, millions of buildings are located in a region with calcareous water. While this is good for our bodies, it is bad for pipes, heating, faucets and household appliances. The most common problems caused by calcareous water are:

Frequent descaling

Lime in water forms persistent deposits, especially in household appliances. These must be removed regularly, otherwise they may be damaged.

Lime on surfaces

Whether in the bathroom or in the kitchen. When water evaporates and lime dries, calcium deposits can often only be removed by laborious scrubbing.

Scratchy feeling on skin & hair

Lime is not only deposited in pipes and equipment. But also on skin and hair. That often feels unpleasant.

The retrofittable water conditioner for your domestic water connection.

The good news: Homeowners can protect themselves from lime. So-called water softening or lime protection systems are installed at the domestic water connection of a building. Lime is treated in this way even before the water flows further into the house. As a result, calcium deposits are efficiently reduced. Our AQON PURE lime protection systems are particularly environmentally friendly and can be easily retrofitted. On request, we can even offer an installation service at a fixed price from one of over 400 specialist companies.

and without the water being filtered out. Today I screwed the strainers on the taps for the first time. I was easily able to rinse off the few limescale particles under running water. Nothing more was necessary. Cleaning the shower and bath, including the joints in the tiles, is also much easier. I hope that many people choose this environmentally friendly, healthy, and affordablesolution. The customer service was quite good, and installation went smoothly, at a fixed price by a local specialist.

craftsman, everything was simply top notch. The product is barely thicker than the water pipe and does what it should. No more limescale deposits after two weeks. We used to treat everything with vinegar once a week … we are very happy – plus it’s all maintenance-free and there are no running costs. Highly recommended!

the white ceramic again with a little brushing. Completely without using harsh cleaning agents. The system itself is completely integrated in water pipe system and therefore barely takes up any additional space. Visually even an eye-catcher, as the surface is made of high-quality brushed stainless steel. All in all: finally less cleaning or scrubbing! And that after just a few days of installation. Now after 4 months of installation, the weekly use of anti-calcifying agents in the household has been reduced to zero.

Reducing or preventing limescale deposits in your hot water generation system has been proven to save energy. This is because limescale deposits on the surfaces of heating elements have a low thermal conductivity. They act as insulation. As a result, considerably more energy is required to heat water. [1] For example, a 3 mm thick layer of limescale reduces heat transfer by up to 60%. [2] Just 2 mm of limescale leads to a 12% increase in energy consumption for hot water production. [3]

The best thing about our one-year money-back guarantee? 97% of our customers never need it. In the unlikely event that you are not satisfied, you can return your AQON Pure system within 365 days without giving any reason.

AQON PURE limescale protection systems are exceptionally durable. Depending on the product variant, your AQON Pure limescale protection system can be used for up to 10–20 years – with no running costs, no maintenance and no consumables.
