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

Die Waterdrop C1SL ist eine ordentliche Einstiegs-Osmoseanlage für die Arbeitsplatte: ohne Installation, mit Mineralstufe und einer Kartusche, die 12 Monate oder rund 4.160 l hält. Das Wasser schmeckt neutral, Chlorgeruch und Kalk im Wasserkocher verschwinden. Für ein bis zwei Personen passt sie gut. Der Haken: Es gibt nur Raumtemperatur und der Rohwassertank hinten muss ständig heraus.

Pros

  • Läuft ohne Installation, braucht nur Steckdose und 29,7 x 21,1 cm Stellfläche
  • Eine Kartusche hält 12 Monate oder rund 4.160 l
  • Sparsames Verhältnis von 3:1 Reinwasser zu Abwasser
  • Wasser schmeckt neutral, Chlorgeruch verschwindet, Wasserkocher bleibt kalkfrei
  • Werkzeugloser Filterwechsel mit Wechselanzeige
  • Pumpe filtert leise genug für die offene Wohnküche

Cons

  • Rohwassertank sitzt hinten und muss zum Füllen jedes Mal heraus
  • Kein heißes oder gekühltes Wasser, nur Raumtemperatur
  • Nur 0,95 l Reinwasser, ab drei Personen mehrmals täglich nachfüllen
  • Konzentrat fließt zurück in den Rohwassertank, Rest muss ausgeleert werden
  • Kein Systemzertifikat nach NSF/ANSI 58 für die Filterleistung
