Löhnert GmbH aqua blue

It lives up to its promises (quick installation, the water feels softer, virtually no limescale—which is easy to wipe away)

Delivery and installation were quick and easy. The results were also visible right away.

The system lives up to its promises. The appliances need to be cleaned much less often, and there are hardly any "water marks" left on the shower. I would buy it again in a heartbeat.

The water in the Swabian Alb is very hard, which leads to heavy, stubborn deposits in pipes and especially in appliances used for cooking (kettles, coffee makers, aerators). With aqua blue, these deposits are softer and can be easily removed with citric acid. The “drinking water” straight from the tap tastes better and actually has a blue tint in the glass. Before the “aqua blue system,” I used a “magnetic system” for many years, which also altered the calcium structure. Aqua blue has a significantly better effect.

I bought the Aqua Blue unit for my rental apartment in Spain.
The tenants are very satisfied; the tap water feels noticeably softer to them, and the limescale deposits on sinks and faucets are much easier to remove.
Back home in the Rhineland, I’ve been using it since last year—the limescale doesn’t disappear, but it’s much easier to remove, and the water feels more pleasant on the skin.
In that respect, both my wife and I, as well as our tenants in Spain, are very satisfied.

I'm really impressed by how much the limescale on my kitchen appliances has decreased. I would have thought it might go down by about 50%, but in my case it's between 80 and 90%.

After just one day, we noticed such a noticeable improvement in the water quality that our enthusiasm for the system knows no bounds.
You can feel the difference even when washing your hands, and in the shower, the way your skin and hair feel is completely different.
Tea and coffee taste good again without having to constantly buy bottled water, and the tap water is finally enjoyable to drink.
The portable device also turns any unpleasant water on the go into a fresh, tasty beverage in a matter of seconds.
A technology we wholeheartedly recommend and service that’s exceptionally good.

Less limescale on your faucets and softer water for your skin and hair.

Very simple and quick installation. The water is immediately softer, and limescale on faucets and objects is easier to remove. A microfiber cloth for chrome alone is sufficient—no cleaning agents needed. Limescale buildup is generally reduced. However, the effect seems less noticeable on glasses.
We have connected AquBlue to the pipe leading to the drinking water faucet behind our reverse osmosis drinking water filtration system to produce hexagonal drinking water. This gives us a great sense of having optimal drinking water with the best bioavailability and purity.

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
