The installation went quickly and smoothly. It was only three days ago, so I can’t say anything about the effect yet.

It seems like the water is softer – but I’ve got nothing to base that on. More on this later.

Six months after installation, I have quite a positive impression. The coffee machine runs without a limescale filter

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.

test report

Has AQON PURE been tested by Stiftung Warentest?




The last test of lime protection systems at Stiftung Warentest was carried out in 2000. For softening systems with salt (ion exchangers), the last test took place in 1994. AQON PURE lime protection systems did not yet exist at that time. It was therefore also not possible for AQON PURE to participate in Stiftung Warentest. Since the last test by Stiftung Warentest was over 20 years ago, the test results from that time are only partially up to date. Devices based only on the effect of electric or magnetic fields performed particularly poorly in the test. These are often magnets or coils that are only attached to the pipeline from the outside.

In the test carried out by Stiftung Warentest, the devices with the best test results included catalytically operating systems based on the principle of seed crystal formation. AQON PURE lime protection systems also use this process of catalytic seed crystal formation.


Characteristics of the test at Stiftung Warentest:

  • Completed in the year: 2000
  • Number of devices tested: 12
  • Device prices of the tested devices: DM 80 to DM 3,535
  • Test water hardness: 25.8 °dH
  • Scope of testing: limescale protection, environmental and health properties, technical design, handling and safety
