Verdict

Pros & cons

Die OsmoFresh Fusion Air ist ein Auftischgerät ohne Installation, das Leitungswasser zuverlässig weich und mild filtert. Für Singles und Paare in Mietwohnung oder Büro taugt sie gut, auch für Tee per Flex-Taste. Der Haken: Statt 95 °C kommen meist nur rund 80 °C an, vorher läuft kühles Wasser nach. Dazu muss der 4,7-l-Tank jedes Mal ganz geleert werden, und die Herstellerkartuschen sind teuer.

Pros

  • Weiches, remineralisiertes Wasser mit 2,5 °dH, Kalkränder im Wasserkocher bleiben aus
  • Keine Installation nötig, nach rund 20 Minuten startklar
  • Flex-Taste mit 40 bis 90 °C in 5-Grad-Schritten für Tee
  • Abwasserverhältnis 2:1, halb so viel Abwasser wie beim Vorgänger
  • Werkzeugloser Filterwechsel in etwa 5 Minuten mit Wechselanzeige
  • UV-C-LEDs in Innentank und Auslass, Standby unter 0,5 W

Cons

  • Heißwasser kommt mit rund 80 °C statt 95 °C an, erst nach 5 s Vorlauf
  • Tank muss nach etwa 2 l jedes Mal komplett geleert und neu befüllt werden
  • Nach Heißwasser läuft an ungesperrter Taste kurz heißes Wasser nach
  • Nur teure Herstellerkartuschen, Standardfilter passen nicht
  • Tankdeckel und Haken verklemmen leicht, Anschlüsse tropfen beim Tragen

Die Toshiba TWP-TSR75TDE filtert ohne Installation und liefert nach etwa drei Sekunden Wasser bis 99 °C in sechs Stufen. Sie passt zu Tee- und Kaffeetrinkern in Single- oder Paarhaushalten, die nicht in die Spüle bohren dürfen. Der Haken: Der Tank muss mehrmals täglich nachgefüllt werden, der Restwassertank bei jeder Füllung geleert, und die teure herstellereigene Kartusche ist eher nach 6 als nach 12 Monaten fällig.

Pros

  • Filtert und erhitzt ohne Installation, auch für Mietwohnungen
  • Heißes Wasser nach etwa 3 Sekunden, sechs Stufen bis 99 °C
  • Eigene Stufe mit 46 bis 50 °C für Säuglingsnahrung
  • Gefiltertes Wasser schmeckt weich und neutral
  • Kindersicherung sperrt das gesamte Bedienfeld
  • Eine Kombikartusche für alle Stufen, Wechsel nur eines Teils

Cons

  • Frischwassertank klein, Familien füllen drei- bis fünfmal täglich nach
  • Restwassertank muss bei jeder Füllung geleert werden, Verhältnis nur 2:1
  • Herstellereigene FIST-Kartusche teuer, Wechsel laut Anleitung etwa alle 6 Monate
  • Gründliche Reinigung braucht Reinigungsfilter und Mittel, beides nicht im Lieferumfang
  • 200-ml-Taste gibt nach Abbruch zuerst die Restmenge aus
