Aquavolta® Cavendish 2.0 countertop &/or undercounter ionizer | produces filtered, alkaline water with H2 gas

The one in 2017 further developed water ionizer with the name AquaVolta® Cavendish 2.0 on- and under-table ionizer offers an outstanding and long-lasting yield of molecular hydrogen thanks to the nine grid-shaped electrodes with a particularly efficient platinum coating.

He was led by Yasin Akgün, Dipl.-Ing. TU Munich helped develop it because we work closely with the manufacturer and he implemented our wishes. A new addition is the optional under-table installation with its own operating tap. The rotary control is now external as a fine control valve. The device is operated using an ON-Off button. A rinsing device can be activated in the menu if the water is very hard. Videos will follow soon.

Its sophisticated limescale protection makes it an all-rounder, from hard to extremely hard water with water hardness over °dH 20.

Conclusion: Currently one of our best water ionizers in our range, highly recommended!

Advantages AquaVolta® Cavendish 2.0 water ionizer

  • The AquaVolta® Cavendish 2.0 water ionizer has a larger multi-layer filter with tourmaline and calcium instead of simple activated carbon
  • can be connected directly to the cold water pipe and can now also be hidden under the sink. Then it will be
  • has a dial for water flow regulation, ideal for connecting to the tap: the water ionizer starts when water comes in and stops when you stop the water supply at the tap. The rotary control serves as a one-time flow regulation.
  • Color coding of the clear screen
  • More stable and radiation-free SMTP technology, instead of a toroidal core transformer
  • The AquaVolta® Cavendish 2.0 However, compared to the Kangen Enagic water ionizers, there is no added salt to produce anolyte and catolyte, in case that would happen ECA Plus Water Tractor in question

Named after Henry Cavendish, (born October 10, 1731 in Nice; † February 24, 1810 in London), the discoverer of hydrogen

The filthy rich and solitary English nobleman Henry cavendish is perhaps the most important researcher in concrete physics of all time:

Because he really proved Isaac Newton’s “fantasy” of gravity and was the first to “weigh” the earth. You have to be so skeptical and stubborn!

And he destroyed the millennia-old myth of the “original element” water by proving hydrogen as an energy-rich component of water as “flammable air”.

This combustible air is nothing other than the sole energy prospect of future humanity once oil and natural gas have been burned. Lavoisier, the discoverer of the other water component “oxygen”, actually only served dessert. The main course actually comes from this phenomenal maverick Cavendish. Respect. And that's why we named this excellent hydrogen machine, which we completed after years of struggle with the manufacturer, after him: Henry Cavendish, Esq. – we thank you for your incredibly important discovery!

Henry Cavendish 1731-1810 was the first scientist to discover hydrogen
Aquavolta Cavendish water ionizer - display functions

The total filter running times of the filter are shown in liters on the display

The filter running times for the filter are shown in the display to the nearest liter. This means you always have an overview of how much water you have already used. As soon as a filter change is necessary, the inherent diagnostic module becomes active and also shows you the required filter change on the display. This saves you additional maintenance work. The filter should still be changed after 6 months at the latest according to the German DIN standard.

The pH value shown on the display at the factory applies to medium hardness levels and flow rates of around 1,5 to 2,0 liters / minute. The displayed pH value can be adjusted to the actual value in the menu settings. This also applies to the filter running time, which is preset at the factory to 4000 liters. No other manufacturer in the world offers these two features.

Multifunctional display: Displays the pH value, water flow, as well as filter flow and time

Hardly any other water ionizer can compete with the clear arrangement of the touch buttons (touch control sensors) and the information displayed on the very elegant, brushed stainless steel front in terms of ease of use and design.

The following setting options are available: time and date, basic performance of the water ionizer, fine adjustments of the individual levels, changeability of the displayed pH values, language setting, volume including muting, filter running time.

Please do not change the rest of the settings. Basically, the water ionizer is preset at the factory for average water values. You don't have to change anything except the time and date.

Filter reset Cavendish 2.0: Press Mode + Voice button at the same time. Then press and hold the alkaline button several times.
Then press the voice button again to save the setting.

Water cell with 9 electrodes water ionizer alkaline water Allsbon

Standard: 7 titanium electrodes (mesh) with platinum coating for particularly high values

The titanium electrodes (plus-minus poles), sprayed multiple times with platinum using a patented process, perform the fundamental role of separating purified water into alkaline and acidic water. However, there are huge differences in the basicity and quality of the active water of the various water ionizers, which are achieved by the thickness and type (galvanically applied or sprayed) of the platinum-titanium coating and the number of electrodes as a whole.

Each of the 7 electrodes has three electrodes applied using a patented spray process, which applies the layers of platinum particularly perfectly and leaves no gaps. In contrast to water ionizers with 5 electrodes, this outstanding 7-electrode ionizer is also suitable for very hard tap water above °dH 27. Values ​​up to pH 10,5 and above can be achieved safely and permanently, even with hard water.

An additional advantage of platinum titanium coating is that it has high electrical conductivity and is a harmless material to the human body. Furthermore, the heart of the AquaVolta® Cavendish 2.0 (formerly Cavendish 9) water ionizer is characterized by extremely low power consumption and good electrolytic performance. Very high pH and especially redox potential (ORP) values ​​can be achieved.

Easy regulation of the active water strength using an external rotary valve

With the rotary valve you can easily turn this system on and off.

You can also use it very flexibly and, in addition to the permanently selectable levels, get the most out of it because you have the option of achieving all pH values ​​between pH 4 and pH11 in 0,1 pH levels and can determine exactly which pH value you want want to set.

By reducing the flow, greater ionization of the water is possible (and vice versa), as the contact time between the electrolytic cell and the water increases. More electrons flow into the water and convert it or create an antioxidant effect (ORP value) due to the excess of electrons in the water. Since flow ionizers are closed systems, the effect of the electrolysis process is much better and you end up with freshly charged water full of OH ions, hydrogen and electrons.

Flow regulating valve 1-4 inch plug connections

Particularly powerful with a total maximum output of up to 250 watts

Thanks to the high maximum power of the water ionizers with up to 250 watts of maximum power consumed instead of the usual 90 watts for household ionizers, flow rates of more than 2 liters per minute can also be set, so that the AquaVolta® Cavendish 2.0 Water ionizer meets the highest performance requirements and is also suitable for the catering sector.

Nevertheless, the tap water introduced and its mineralization and, above all, the water flow, which you should adjust once, play a decisive role in what results will be achieved in the end.

Please note the video on the right about the influence of the water flow on the pH value, ORP value and, in absolutely measurable numbers, the dissolved molecular hydrogen content.

Influence of water flow on hydrogen content & pH value

SMPS transformer switching power supply water ionizer better than transformer

Transformerless SMPS power supply for minimal heat and electrosmog load

Classic power transformers (transformers), which are widely used in water ionizers, are only designed to withstand a power supply of 100-150W/24-30V/5A. As a result, a lot of PCB program errors or malfunctions occur because individual components overheat, which generates excess current during the electrolysis process. Instead, the manufacturer IONIA is consistent SMPS as power supply .

It reduces the overheating rate of the device even with more than twice the output current compared to other devices, thereby increasing both the cost-effectiveness and safety of the device by reducing the program error rate.

All water hoses in the device are biocompatible and food-safe

Flexible, particularly long outlet tap made of special, lime-repellent plastic. This clever choice of material (biocompatible and food-safe) keeps the outlet free of any limescale accumulation in the long term.

Intelligent self-switch-off protects against water damage

The device also has an intelligent automatic switch-off. If, for example, there is a water leak or there is insufficient water supply, this function can offer valuable protection against water damage.

    Dear Mr. Akgün,
    nice to hear from them.
    You didn't promise too much when you bought the device. We are very satisfied with the ionizer so far, it works reliably and we have reached 2.100 liters of remaining volume with the first filter cartridge.
    (That was an immediate indication for me to order replacement cartridges straight away :-)
    So far I have descaled the ionizer twice after 2 months, it worked well and is manageable in terms of effort.
    My children and I now drink alkaline level 4 and avoid “normal” tap water wherever possible because we simply don’t like it anymore.
    I even use alkaline water for cooking, making tea and coffee, watering flowers and washing fruits/vegetables.
    My unspecified pain has improved, we sleep better and have more energy during the day.
    Thank you for your competent work and very familiar and customer-friendly service.
    Kind regards

    Hello dear Sara
    Yes, it's normal, we show in the video:
    The video above
    Yes, increase the flow, then the water will be weaker. Your water is currently quite strong.
    See you soon
    All the best

  3. Sara A. -

    Good afternoon Mr. Akgün,
    then both the fishy and the white are normal?
    Should we increase the flow then?
    So far we are happy with the Cavendish, we are sleeping better and have more energy during the day, but it may be a little early to see further results.
    Best regards,
    Sara A.

    Hello Yasin,
    Short feedback: I'm very happy with my Isionizer. Your brother-in-law installed it really well and everything is stored perfectly, looks good and works great.
    He wanted to get me an adapter to connect to my daughter's house and I said I'd come by on Thursday. I would actually be in your area on Wednesday – around 10 a.m. Can I pick up the adapter there?
    Best regards,

    Dear Yasin,
    ... I've been using the Cavendish since Saturday. I am absolutely thrilled!
    My ankle pain is gone. My digestion is better. I feel 20 years younger! I completed a really long program on the exercise bike on Sunday – without getting tired. The Cavendish is an extremely great device with great technology. Thank you that you can buy things like this in Germany.
    Alkaline hydrogen water is really doping. And completely legal.

    Yasin Akgun -

    Hi Timo,
    Thank you for your kind words, can I leave it like this online please:
    Yes, of course, the flow at the wastewater is a little less (40%) instead of at the outlet at the top (60%), so the product from the hose at the bottom is always a little stronger, this is the case with every ionizer.
    And I think the most important thing is that it's delicious. Where else can you get water like that?
    Regarding the leak:
    Have you replaced the hose piece?
    Then I will send you a new sieve piece with hose and also the plug-in part, the elbow connector with socket by letter on Monday
    Let me know if it worked.
    Looking forward to your answer.
    All the best

  9. Timo -

    Dear Yasin,
    Thanks again for the information and your advice. We then leave it activated with the 10-second rinse.
    By the way, we are constantly thrilled with the device and the delicious water. And I am also pleasantly surprised at the extreme pH values ​​the device can produce via the “wastewater” outlet (from measured approx. pH 2,5-3,0 to approx. pH 11,5).
    Unfortunately, we still have a tiny technical problem: water is leaking out drop by drop from the tap water inlet. The droplets form at the short connection between the sediment filter and the device inlet (i.e. the short, preconfigured connection hose). I've already replaced it, but the drops still keep forming there. Do you perhaps have a tip about this? Is it possible to make the connections even tighter with the included white PVC tape? (I haven't figured out the purpose of this yet.) Or should I try replacing the hose connection again in the hope that it will then seal?
    Thanks for the occasional feedback again.
    LG Timo

    Hello family H.,
    Lose 2,5kg in 3,5 weeks and get more fitness and energy, less
    Craving for sweets and coffee are considerable improvements
    with an otherwise unchanged lifestyle is most likely to occur
    the changes can be attributed to drinking. It would be interesting whether
    There are also improvements in blood values, especially in the liver and kidneys
    be objectified. But I would still do that a few weeks ago
    Wait for comparison measurement.
    The fact that they urinate more is probably due to the increased amount they drink
    together. It would be interesting to observe the color of the urine to see if they
    gradually gets brighter. The saliva test also enables good control,
    as described in my human service manual (download via
    the link list below).
    It is not clear at what level you drink, as it depends on the type
    of the water other values ​​come out. the long-term recommendation is pH 9 –
    9,5. You should check to see if this is the case.
    Yes, that's exactly how I do the boosting in the office, especially because I
    Alkaline water tastes better than neutral water. They can do that too

    Hello Mr. Asenbaum,
    I warmly greet you after the first 3,5 weeks of experience with various hydrogen preparation processes.
    Basically we are very satisfied. What we notice:
    – I have more energy, which I notice clearly when playing tennis and cycling 15 km to work
    – I lost some weight, about 2,5 kg, now 77 kg
    – I no longer take alkaline powder, which I have done every day for several years
    – I also sleep a little less and feel fit
    – I have less desire/need for coffee and sweets
    – I have to urinate significantly more
    Can this all be related to the hydrogen water? I haven't changed my lifestyle otherwise, so the connection is obvious.

    Our drinking behavior:
    At home we drink the water from the Cavendish, level 4, approx. 1-1,5 l/minute, a total of 2-3 l/day.
    I take water from the ionizer with me to the office and boost it 10' with the Age2go2,8 every now and then. Does that make sense? The booster itself does not produce alkaline water.
    When I'm at conferences, training courses or in the sauna, I take filtered water with me and throw half a teaspoon of Hydronade into about 400ml of water and drink it. You shouldn't use water from the ionizer, which I just read again in the instructions. Correct?
    I would be happy to receive feedback on our experiences and current drinking behavior.
    Yes, that's a first experience report. It's really exciting! It's great that you've stuck with it so intensively for a long time now and it's a shame that our paths have only crossed now.
    Greetings Hans-Georg H.

    Hello Yasin,
    I bought a Cavendish 9 from you as a table-top ionizer and I am still very satisfied. However, in order to improve the taste and water quality, I really want a Schauberger water swirler attachment on my device.
    I fell in love with the following part:
    My question is, how can I use this in conjunction with my Cavendish? Unfortunately, probably only as an under-table installation with a new tap, right? Or do you have another idea?
    Thank you very much and best regards

  20. Yusuf Ş -

    Hello Mr. Akgün, I have the next payment date on December 15.12.19th, 870 for the amount of €435. I wanted to ask, since I chose installment payment when I purchased it, whether I can transfer €15.1.12 and pay the last installment on January XNUMX, XNUMX??? That would be a great help to me. I would ask you to perhaps communicate this with your sister, since she does the accounting. To the device. I am very satisfied and glad that I decided on it. Top device.

    Hello Mr Akgün,
    I hope you and your team are doing well.
    After all, the whole family is enthusiastically using the water ionizer you purchased.
    Today I would like to purchase a (if possible a return at a cheaper price) Biomat Amethyst Professional heat mat,
    order in the dimensions specified above.
    We will send the Vulkun 5000 limescale converter you received for testing back to you in its original packaging. It will arrive
    out of the question for us. We keep the magnetic limescale converter that we have already paid for.
    I would like to hear from you briefly.

  22. Frank C. -

    Hello Mr Akgün,
    Thank you very much for the information, then I'll be reassured if everything is OK.
    Otherwise I am very happy with the Cavendish. Water tastes much better and is more pleasant to drink than straight from the tap.
    So it was a sensible purchase!

    With kind regards,
    Frank C.

  23. Jurgen N -

    Thanks for the feedback, but I'm happy to pay for the filters. They helped me a lot with the purchase (and Mr. Asenbaum!) with the decision and we haven't regretted it since. On the contrary, we are always happy when we can drink our water at home after being away. Meanwhile, the children's friends are also happy to accept this and tap water. What is noticeable is that after descaling (every 4 weeks) it still tastes fresher than before. What I said in the video about level 3 was what we had done for about 1,5 years. After an inflammation (in the body) I temporarily set it to level 2 and left it that way ever since. Since then, the vessels are no longer as cloudy and it seems more pleasant to drink. By the way, our pets get the same water and I am convinced that there is nothing wrong with it. …

    Hello Mr Akgün,
    sorry I'm absolutely country under.
    We have had the following experience. …
    No calcification at the water outlet
    Our filter is set to 3065 – I have descaled 4 times since I started using it. We had ZERO limescale in the pumoen container. That surprised me
    because the water containers we tap into become calcified. A little less than before, but they calcify.
    The water tastes good even at level 4
    I also use the hydrogen maker. Makes you feel good. Effect – I don’t know.
    We are extremely satisfied and would be happy to serve as a reference!

    By the way, big compliments to your husband, who explained the installation of a sink in detail via video, which helped a lot with orientation!
    I have two questions: firstly, I couldn't get a black seal at the hardware store and wanted to ask how much something like that costs you?
    The other question is: I have a friend who has a leveluk sd501 device and needs a cartridge (hg-n). How much does a cartridge cost me from you?

    Hello Mr Akgün,
    does not matter. I was just wondering, hence the question. The package arrived today and I'm going to try out the booster right away.
    The ionizer works perfectly, the dishwasher doesn't, but that doesn't matter for now as we're moving in a few days and I hope to have better luck with the installation in the new house. 😀
    The water generally tastes great and I have also noticed that my good tea and coffee also taste a little more intense...

    After receiving the Cavendish 9 a few weeks ago, I got around to installing it 3 days ago.

    The water tastes great and we are already having a lot of fun with it. ..
    …Thank you very much in advance for your brief feedback!

    Best regards,
    Michael K.

    Hello Mr Akgün,
    I tested the Cavendish over the weekend and have to say: I AM IN LOVE WITH IT!!!!!
    I like it much, much better than the other one. When I say “liked” I don’t mean the way he looks, but the way he works.
    I completely agree with you when you say the values ​​remain constant and I love that about it. I love the regulator on its body to adjust the flow rate!!!
    I have the feeling it is much more robust in terms of its inner workings!!!!
    So this is my device and I won't give it back.
    I carefully packed the other device today and will take it to HERMES tomorrow.
    I will send it to the Aquacentrum in Munich.

    Hello Mr Akgün,
    Thank you; Videos are very interesting and informative. Also make it easier to use the water ionizer. By the way, I connected the Cavendish 9 as soon as I received it. We are currently using alkaline level 1 at 2 liters of water flow; I think it's initially enough for the daughter who has cancer. In your opinion, is it advisable to purchase a hydrogen booster as a supplement? Or just use the tablets that were sent with you? I think the announcement language at Cavendish only works in English, right?

    Best regards, Lars B.

  40. Tom Flanderka -

    …The “Moses 7” still works well and we are very satisfied.
    best wishes

    Hello Yasin

    first feedback:
    – In the alkaline range, the device creates stable values ​​around pH 10 (level 4 and 1,3 l/min)
    – H2 saturation appears to be present
    – I experience the detoxifying effect with headaches and muscle effects (I probably have to slow down a bit at the beginning because I only drink water)…

    ....I don't drink anything else anymore, I don't have to carry boxes anymore

  42. Tom Flanderka -

    ...what I have noticed in the relatively short period of time of drinking ionized water is that the desire for food, a solid intake, has changed and lengthened over time - without feeling a decrease in performance. (has the metabolism of food also improved?)…
    Continue reading the detailed report from the therapist from Munich, Thomas Flanderka

  43. Tom Flanderka -

    I'll be out from tomorrow until Friday morning, then I'll let you know what we decided on table top or bottom table.

    But what I can say about my experience over the last few days: the water from the device tastes good to me;
    Yesterday while “exercising (running)” I noticed that I was able to run very persistently, even though I hadn't done much for weeks. ->If it is related to the water, then this was a definitely noticeable, positive experience!

    see you then and see you soon,


  44. Berthold K. -

    Hello Mr Akgün,
    Do you know the highest praise from a Swabian?
    …. ?
    è When he says: “Not bad”
    And since I'm a Swabian and economical with words, I'll just say “not bad”. J
    And secondly Pictures say more than a thousand words, so here are a few pictures from our kitchen, including connection technology.
    So far we are super satisfied.
    Kind regards from Berthold K.

Biostone multi-stage activated carbon filter | AquaVolta® Cavendish 9

Thanks to the world's leading multi-layer activated carbon granulate filter technology Manufacturer Kuraray The following pollutants are effectively and safely removed:

Drug residues, hormones, agricultural residues such as pesticides and insecticides, and other typical man-made chemicals.

The filter cartridge also contains BioStone ceramics made of tourmaline (semi-precious stone). When the water hits the tourmaline, tourmaline develops its effect because it naturally emits infrared radiation (FIR), which in turn changes the water structure by creating exclusion zones (Gerald Pollack) improved and the water prepared for ionization.

According to the DIN standard, the filter should be changed every 6 months. However, we have given you the OK to change the filter after 4000 months at the latest, as long as the 12 liters have not yet been exceeded. In all of our water filters, silver ions reliably counteract germination through long service lives. This means you have our OK to change the filter every 12 months. Tap water is harmless in Europe anyway; filtering, like the airbag in a car, is a simple safety measure.

Answer from Yasin Akgün about the differences in coating processes for electrodes for water ionizers

Hello Mr. O.,
So the Kangen sellers and others make the galvanic the No. 1 and say the spraying process is low quality

The manufacturer of AquaVolta® Cavendish / Moses 9 water ionizer has so far produced the most models and numbers in the world, is the oldest manufacturer and the first in Korea
And they have developed a special spraying process that offers the highest levels of efficiency
We can confirm that too.
The highest hydrogen content and also the highest values ​​in terms of pH or redox potential.

Attached is their document about it or I have created an FAQ:
Here you go to FAQ

The AquaVolta® Cavendish 9 / Moses 9 is probably my best device currently.
Therefore, you have my fullest assurance, it is in stock as of today.
All the best
Yours, Yasin Akgün

    > Installation of water ionizer


    Installing water ionizer on the faucet

    A rotary control on a water ionizer is only an advantage in a faucet installation compared to the water ionizers with a solenoid valve and an on-off control (e.g EOS Genesis or EOS Touch), which is connected to an external Flow regulating valve be delivered.

    Only the AquaVolta Moses-7 water ionizer, which is the successor of Nexus X-Blue water ionizer, AquaVolta Basic and the Allsbon Family have a rotary valve integrated into the front of the device housing. This is particularly useful in everyday practice, especially when installing faucets, as the flow has a major influence on the end result.

    This is explained again in the operating and filter changing video in this FAQ article, which is analogous Flow regulating valve in the Permanent installation used to set the appropriate flow.

    Of course, it is ideal if you can see the current flow on the water ionizer display. That's just at AquaVolta Moses-7 and at Allsbon Dion Family is possible.

    How do I install a water ionizer on the faucet in just a few steps?

    Video | Faucet installation with diverter valve

    Installing a water ionizer on the faucet

    The simplest method is the Water ionizer installed on faucet, as can be seen in the diagram on the left. This form of installation can be carried out by anyone.

    In just a few minutes, a layperson can connect the supply hose (feed water) of the water ionizer. All you have to do is turn the lever and instead of coming out of the tap, the water flows through the water ionizer via the feed water hose.

    Attention: Complete the installation Branching off from the tap is not possible, if it is a faucet on a Low pressure boiler acts. connect. Your dealer carries almost all other faucets suitable adapters.

    Please send us a photo of your faucet. Best by email: or via WhatsApp: +49 179 2166231

    Video: Installation on the faucet with a diverter aerator

    Are you sure the water ionizer stays installed on the faucet only?

    This short video shows the typical installation of a water filter on the faucet. Analogous to the water ionizer, a Carbonit table-top filter (Alternative to Carbonit San Uno: Aquaphor Modern) or most of the commercially available ones Tabletop filter Installed.

    In this case, our main recommendation is to use devices that have a rotary control integrated into the device housing. That would be it AquaVolta Cavendish 9, AquaVolta® ECA Tractor or the AquaVolta Basic Tabletop ionizer.

    The advantage is that, in contrast to water ionizers with an ON-OFF touch sensor (solenoid valve), you do not have to also press the ON-Off button. As shown in the video, the water ionizer starts after the water comes in from the tap changeover valve. Nevertheless, those too Water ionizer with an ON-OFF solenoid valve are very suitable for installation on the tap.

    Advantages and disadvantages of a changeover valve

    • Advantage of the deflection aerator: If you have a faucet with a mixer tap, you can not only produce cold active water, but also lukewarm. Caution: Since most flow ionizers are sensitive to hot water (—> diaphragm melts), there is a risk of overheating and damage. Therefore, always let the water run through the tap first and test the temperature. The water should not be warmer than lukewarm (370 C). The manufacturers specify different maximum temperatures that must be strictly observed.
    • In some devices, which I call low pressure ionizers, the deflection aerator the only connection option. These devices do not have a built-in valve, so the water flows through unhindered. That's why you can't connect them directly to the water pipe, but you have to connect a tap in between so that the water doesn't flow continuously. These low-pressure devices can usually be recognized by their soft supply hoses with a diameter of more than 7 mm.
    • Disadvantages of the deflection aerator: It cannot be connected when a low pressure water heater is connected. Regulating the flow rate requires a certain degree of sensitivity. The feed water hose on the tap is a nuisance when working in the kitchen and is aesthetically unsatisfactory for Western tastes.
    • There are special alternative taps as accessories for such devices if you do not want to or cannot use a deflection aerator. The alternative tap is positioned next to the ionizer on the edge of the sink with a hole through the kitchen countertop and the ionizer is connected to it. The alternative tap gets its cold water from the cold water angle valve at the bottom, from where it is branched off using a T-piece. The water supply can be regulated using the rotary knob at the top. The hose with the draining sour water is also connected and the sour water flows neatly from a stainless steel tap without a hose hanging into the sink. This is a good solution aesthetically and technically, but requires an installer because of the work required on the pressure pipe. Please contact us about this special event.

    Descaling | Water ionizer maintenance

    Descaling a water ionizer with a flow dial

    If you own one of the water ionizers listed below, be sure to watch this video.
    In short: Make sure that the pump can pump the citric acid solution into the filter. The rotary control should therefore always be set to OFF, i.e. in the off position. The following water ionizers have a flow control dial and are descaled analogously:

    Descaling ionizer with flow regulator | Nexus X Blue > The predecessor of the AquaVolta® Moses 7

    This video shows the individual descaling steps that must be observed, especially for water ionizers with flow regulators.

    According to the latest experience, you can only descale in one pass, you don't have to turn the ionizer on and off between descaling.

    The duration can also be extended up to 4 hours depending on the level of use and calcification. If there is severe calcification, please replace the citric acid solution after an hour.

    Descaling does not harm the water ionizer in any way. It's exactly the opposite, descaling is good for any water ionizer as long as you use citric acid and not acetic acid.

    The real question | Heavy metals and ionization of heavy metals in the water ionizer

    Thank you very much, it is noted.

    I know what you think about osmosis water and that this has degenerated into a kind of religious war. But I don't even want to identify with someone like that because I'm always open to new things. Since I value your opinion very much, I would like to give you a point of view that is not easy to ignore (at least for me) and that, if you want to look at it scientifically and strive for the optimum in quality, you inevitably has to deal with the topic.

    I agree with you 100% with all of your arguments for and against RO technology. It is not necessary in itself, as dissolved minerals are also needed for the further processing process in the ionizer and they are actually very important.

    However, this approval requires that the source medium must be uncontaminated in its original form, which cannot be achieved technically by the waterworks alone. We are talking here about an extremely increasing heavy metal particle load, which is in the nano range and neither from the waterworks nor from the filters in the ionizers (which only filter out the worst - particles of 1µ, while a membrane is capable of filtering out particles of 0,0001 micron) can be achieved. These nanoparticles pass through the blood-brain barrier without any difficulty and reach regions where they absolutely do not belong.

    So at the end of the day you may not have quite as nice/high numbers or values ​​and also an increased effort due to the remineralization, but you still have the certainty that no, or a greatly reduced, heavy metal spectrum has ended up in the water, which is not belongs in the body and, as you yourself say, “could be made even more dangerous by ionization”.

    I don't want to convert anyone or force an opinion, but I would find it interesting if you could briefly comment on these arguments, perhaps also pointing out whether additional minerals would be needed in addition to the mineral mixture to remineralize 80 mg of calcium and 20 mg of magnesium and whether This information refers to one liter of water.

    Thank you for the exchange and your perspective

    Kind regards

    Answer from Karl Heinz Asenbaum about water filtration and heavy metals and air quality

    Dear Mr. Seifert,

    If heavy metals are still found after filtration, you must use a stronger filter performance, if necessary reverse osmosis with calcium + Mg (magnesium) post-mineralization. In this case, I actually recommend reverse osmosis.
    But I have probably seen more than 1000 analyzes that examined heavy metals after the filter of a water ionizer. Of these, less than 5% were such candidates.

    I tend to only advise customers on the most necessary measures. Nobody should spend more money than they have to. In my experience, your statements about the heavy metal contamination of drinking water in Europe, even after normal filtration, only apply to 5% of water intake points.

    I also generally warn against overestimating the danger at the wrong risk point. By far the greatest amount of heavy metal pollution comes from the air, and not from drinking water. With mercury, the worst of all heavy metals, it travels directly to the brain via the olfactory nerve. That's why I think an air ionizer is just as important as a water ionizer. I have one in every room.

    With kind regards,

    Karl Heinz Asenbaum

    Answer from MS About air purification and heavy metals

    Of course, I agree with you about overestimating the danger at the wrong risk point. If you were to adapt this sterile standard to other living conditions, you would have to live in a clean room and would no longer be allowed to leave it. I put 3 of the following products in my room:

    But I don't really know yet whether they really get more than dust out of the air. Hence mixed feelings. I've read a lot of frightening things about air ionizers, which led me to buy oil-based air purifiers. For example, in Amazon “The device not only emits ions, but also the gas ozone. This gave me a strong dry cough... Smokers should definitely google thoroughly before making a purchase decision, as there is a study about possible additional lung damage.” Since this could of course just be targeted disinformation, I am open to new information here too.

    Are there any videos or information material from you regarding air ionizers? From what I understand, you have probably looked into it intensively beforehand, so the question is which product convinced you?

    Automatic descaling of the electrodes through automatic polarity reversal

    Removing mineral deposits such as calcium and magnesium is one of the most important maintenance measures on water ionizers to ensure long-term consistent electrode performance.

    While most water ionizers only carry out a so-called self-cleaning before each use or every 12 to 15 liters of use, in which the poles are only reversed for a short period of 5-15 seconds, the AquaVolta® Cavendish 9 a constant polarity reversal.

    After each use, the poles are swapped to counteract the accumulation of limescale on the electrodes and sensitive membranes. Only two other manufacturers on the European market even have this patented hardware. The advantage of the automatic polarity reversal AquaVolta® Cavendish 9 is that you don't work with a flow reversing motor, but with valves. In practice, this method is more reliable because it breaks down less often.
