Verdict
Pros & cons
Die Jimmy R9 Osmoseanlage ist ein Auftischgerät, das gelöste Stoffe um mehr als 90 % senkt und Heißwasser nach rund 3 s liefert, ganz ohne Bohren und Anschluss. Für Paare mit hartem Wasser, Tee und Kaffee passt sie gut. Der Haken: Statt angezeigter 98 °C kommen höchstens 90 bis 91 °C, und der 5-l-Tank muss nach drei bis vier Karaffen geleert werden – für große Familien zu klein.
Pros
- Senkt gelöste Stoffe um über 90 %, etwa von 321 auf 19 ppm
- Heißwasser nach rund 3 s ohne Vorheizen, nur die gewählte Menge
- Keine Installation nötig, nur Steckdose und Stellfläche von 25,2 x 35,7 cm
- Sparsames Verhältnis von 3:1 Reinwasser zu Abwasser
- Zweite Karaffe kann im Kühlschrank stehen, während das Gerät nachfiltert
- Sieben Temperaturstufen und sechs feste Mengen, etwa für die Babyflasche
Cons
- Heißwasser erreicht höchstens 90 bis 91 °C statt angezeigter 98 °C
- Konzentrat bleibt im 5-l-Tank, Leeren nach drei bis vier Karaffen
- Karaffe mit 1 l braucht 3,5 bis 4 min
- Karaffen sitzen sehr fest, Herausziehen kostet Kraft
- Pumpe beim Filtern gut hörbar, nur herstellereigene Kartuschen
Der Waterdrop K19-HG ist ein Auftischgerät, das Osmosewasser bis 95 °C ohne Installation liefert, und das komplette System ist nach NSF/ANSI 58 zertifiziert. Er passt zu Ein- und Zwei-Personen-Haushalten in Mietwohnung oder Büro, die vor allem Tee und Kaffee zubereiten. Der Haken: höchstens 750 ml am Stück, häufiges Nachfüllen des 5-l-Tanks und Probleme bei sehr hartem Wasser.
Pros
- Ganzes System nach NSF/ANSI 58 zertifiziert, nicht nur einzelne Bauteile
- Heißwasser in vier Stufen von 50 bis 95 °C, Portionen von 150 bis 750 ml
- Keine Installation nötig, nur Steckdose und Arbeitsplatte
- Sparsames Verhältnis 3:1 von Reinwasser zu Abwasser
- Nur eine Kartusche für 12 Monate, Wechsel ohne Werkzeug
- Gefiltertes Wasser schmeckt sauber und weicher als aus dem Hahn
Cons
- Bei sehr hartem Wasser verkalken Tank und Pumpe teils nach wenigen Tagen
- Höchstens 750 ml am Stück, danach knapp 4 min Nachfiltern
- 5-l-Tank muss im Zwei-Personen-Haushalt oft täglich nachgefüllt werden
- Abstellfläche nicht höhenverstellbar, Wasser spritzt über den Glasrand
- Kein Standardfilter, Ersatzkartusche nur von Waterdrop
