TECHNOLOGICALLY AHEAD - TÜV TESTED: Award-winning successor Quella Pro. The Fusion Air is the successor to one of the best-selling osmosis system models in Germany. With only 19.5 cm width, the system fits in any kitchen. Improved wastewater ratio (2:1) and 40% faster filtration. 50% more minerals than in the Quella system. All this in a case that is narrower, lower and shorter. The 4.7 L tank is side for the first time - for better handling. The Fusion series has been awarded the German Design Award 2026 in the category "Kitchen" for excellent product design.
Room temperature up to boiling hot – temperature selection in 5 °C increments, different quantities (150 ml - 2 L) adjustable, fresh osmosis water available at any time. More economical than a kettle, as only as much water is heated as necessary.
No installation required - With large 4.7 L tank: more water, less effort. From a tank filling you get 3.1 L osmosis water. That's over 50% more than the Quella Pro (2L). Simply enjoy freshly filtered water at any time - without installation work. For the first time, the tank is also sideways. This makes daily refilling much easier. Even though the tank got bigger, it feels so lighter.
MORE PERFORMANCE. More minerals. BEST TASTE - 30% less wastewater (2:1), 40% faster filtering and 50% more minerals compared to Quella Pro. Also available with empty filter for pure osmosis water. (From November) We have worked on our Fusion System for over 2 years to show here the most advanced system we have ever built. Osmofresh has been producing osmosis systems for over 10 years. Meanwhile, over 200,000 customers trust us.
INTUITIVE DISPLAY WITH LIVE TDS OF FILTER PERFORMANCE AND MINERALIZATION - Transparent display of water quality & mineralisation for full control.
4-way osmosis filtration. Triple mineralisation. Triple UV-C LED. So a total of 10 levels ensure particularly pure and mineralised water and maximum hygiene. The first and so far only countertop osmosis system that has passed the TÜV Rheinland test for hygiene properties and has been certified. Filter as quick change system easy to change.
