Löhnert GmbH aqua blue

Very satisfied, easy to install, and most importantly, no limescale

The personal contact via phone and email, as well as the installation tips I received after sending photos of my setup—but above all, the noticeable improvement in the quality of our tap water—really won me over!

Based on your description of the product, we can confirm that it works as advertised. The water tastes better than before, but most importantly, the limescale buildup has decreased significantly and is easier to remove, just as you described. We would definitely recommend your product to others.

The water feels softer, cooler, and tastes fresher. The results are incredible!

The product explanation was excellent, and the support during installation was exemplary. Of course, you can’t expect limescale that has built up over 16 years to disappear in just a few weeks. In any case, the water quality has improved.

That was our first impression: we immediately connected the device to the house water supply and started using the small Travel Aqua Blue right away. I placed it on my stomach for a while and felt a strong movement throughout my entire body. My cells were activated and my mood brightened.
After the first sip of Aqua blue water, I saw internally how the light came on in the cells and how the cells throughout my body pushed and activated each other. Pretty quickly, my head also became much clearer, which brightened my mood even more. The water tastes much better than before and is wonderfully soft on the tongue. We automatically drank much more than before. We are very happy that we chose Aqua Blue and the small travel Aqua Blue, because now we can drink this wonderful water everywhere. Thank you very much for your miraculous work!!! Warm regards and gratitude, Karin L.

I was skeptical at first, but thanks to the money-back guarantee, there's no risk. We're now convinced. The described effect of protecting the appliances works. There are still slight limescale stains, but these can be easily wiped away without cleaning agents.

Because it works.

We are a condominium association with three residential units, and after I received a bonus for participating in the webinar, it took us quite a while to finally make the concrete decision to purchase the Aqua Blue system. Löhnert GmbH was very understanding of the situation, and we have now been using the "system" since mid-December 2025. We are very satisfied with the results: much less limescale on fittings and surfaces such as the sink, washbasin, bathtub, and shower; kettle: hardly any limescale noticeable, everything can be easily cleaned with a good microfiber cloth, rinsed, and done! Hardly any cleaning agents are needed (previously, nothing worked without vinegar essence or limescale remover due to our water hardness). Even the toilet bowl has visibly fewer limescale marks and we no longer need "harsh chemicals" for cleaning. The laundry also feels much softer when you hang it up. Your skin and hair also benefit from the good water. As for the price and health benefits compared to chemical descaling systems, there's nothing more to say... ! Everything's great! ALL GREAT! Thank you, Thomas Löhnert and your employees! I also recommend it by word of mouth ;)

After several weeks of use, I am convinced by this product. There is hardly any limescale residue left at any of the water outlets. This has greatly reduced the amount of cleaning required. The water is pleasantly soft, whether for drinking or showering.

I can't say much yet, but the tap water is just as good as still water from the discount store. We now only have 3-4 crates of still water as an emergency supply; otherwise, we only drink tap water. We have calcareous drinking water 18°dH. But now it's very drinkable... Best regards, Hermann Wiggert

We have a water hardness of 17.9 °dH. The water now feels very pleasant and its structure has changed for the better. The kettle is easy to clean after boiling water. My old stainless steel sink (3rd generation) has regained its original shine. The water inlet in our fully automatic coffee machine is largely free of limescale. My wine becomes more velvety on the palate when I place the bottle next to the aqua blue for 30 minutes. I will recommend aqua blue to others and am sure that we will enjoy it for a long time to come.

Immediately after installing Aqua Blue, the quality of our water improved significantly and there are hardly any limescale deposits anymore. I particularly like the change in drinking water brought about by Aqua Blue AB 1005 Mobil: it not only improves the taste of the water but also slightly changes its color.

It doesn't promise too much! Limescale can be easily removed with a towel and it tastes like pure spring water. Before installation, we only drank spring water from St. Leonards... now we're happy to drink straight from our tap... Congratulations to everyone who gets to enjoy this too... Thank you.

The effect was immediate: as described, limescale no longer builds up on the kettle, water jug, glass shower screen, etc., and can be easily wiped off! We are thrilled!

I was very skeptical at first, as it sounded like a miracle cure to me. After reading up on the subject and contacting the company, I was told that I shouldn't expect miracles, as the lime is still in the water, but that the change in the water means that it is removed more effectively and does not settle as easily.

Since you can select "PayPal Pay Later," there is no risk involved. So we decided to give Auqa Blue a try in our home and tested it. What can I say, the lime scale is not completely gone, as it is not a lime scale remover.

However, the limescale is no longer as adhesive and is removed more effectively thanks to the restructuring of the water. The limescale stains have become much less noticeable and are very easy to remove. What we find very surprising is that the stains can be removed without any cleaning agent. Of course, it depends on how long the surface in question has not been cleaned.

The fact is that significantly less or even no cleaning agent is needed for cleaning. Unbelievable! The Aqua Blue devices work really well and make our water softener redundant. It was shut down before we started using Aqua Blue and has not been in operation since. It has now been completely emptied and cleaned and will be sold soon.

Especially with my portafilter machine, limescale deposits used to appear in the water tank after a few days and could only be removed with hot vinegar water. Now it takes a very long time for deposits to form at all, and if they do, they can be wiped away with a simple damp cloth. My wife's kettle is also a very good example. Almost no limescale deposits form in it anymore, and if there are any, the kettle can simply be wiped with a cloth after boiling the water and emptying the container, and the limescale is gone. The water in the bathtub really has a blue tint and feels softer! So we are really very happy with Aqua Blue and do not regret the move in any way.

I see the biggest advantage in the fact that we no longer need salt tablets for the water softener and we are not consuming any unnecessary substances. In addition, the pipes are no longer clogged with limescale, as it no longer settles in the pipes. We can therefore really recommend Aqua Blue and are completely thrilled with the product!

Even my extremely skeptical neighbors (in a row house) were quickly convinced that the water tastes much softer and better, and that the limescale can be easily wiped away. I believe the ingredients are still present. In our region, the tap water is quite good, but at around 17°dH, it is quite hard. Now we are delighted to have "soft" drinking water.

Excellent customer service! The water is much softer and tastes great! Thank you!

I didn't want to believe it, but everything happened exactly as described. I'm thrilled.

Soft water after just two days, no limescale stains on the shower screen, obviously maintenance-free. There's nothing to complain about.
