Water Ionizers

Criteria when purchasing an ionizer | Comparison of water filters and reverse osmosis

Discover the world of water treatment: from filter systems to reverse osmosis to water ionizers. Each system offers unique benefits, and choosing the right water treatment system is critical for your individual needs.

While opinions vary on the definition of 'healthy water' and the benefits of different treatment methods, our focus is to provide you with a choice that meets your specific needs. Whether you prefer soft, low-mineral water or appreciate the taste of highly alkaline water, we have the right solution for you.

A special highlight in our range is the Aquavolta® H2 Rocket Two Stage. As a powerless alternative to traditional electric water ionizers, this device is characterized by up to four times higher Hydrogen content in the water. Although it is technically a flow-through water infuser, it outperforms many flow-through water ionizers in this regard, providing an efficient and environmentally friendly option for water treatment.

Let's work together to find the ideal system for your home that takes both your taste and your health into account.

*H2/hydrogen yield in ppb (parts per billion); at °dH17, highest performance & 0,7 L/min alkaline water

All water ionizers achieve a maximum of approx. pH10,7 & approx. -700 mV with lime-free electrodes & at minimum flow & the strongest ionization level, depending on the water

Only the AquaVolta® Cavendish 2.0 and exquisite, Both with or without the under-table operating tap are very well equipped to prevent the electrodes from calcification, which is why only these should be used with water hardness over °dH16. Everyone else would have to do it too often decalcified .

The H2 Rocket Two Stage and H2 Rocket Multi Stage are the winners when it comes to H2 content and also work without electricity.
