Verdict

Pros & cons

Die OsmoFresh Quella Pro ist ein Auftischgerät, das ohne Installation sehr weiches, neutral schmeckendes Wasser liefert und es per Durchlauferhitzer in 6 Stufen erhitzt. Sie passt zu Mietwohnungen mit ein bis drei Personen. Der Haken: Jede Tankfüllung ergibt nur 1,7 l, du füllst also mehrmals täglich nach, und die 100-°C-Taste bringt nur 80 bis 91 °C.

Pros

  • Sehr weiches Wasser: 1,54 °dH am Auslass bei 22 °dH Leitungswasser
  • Keine Installation nötig, geeignet für Mietwohnung, Büro und Wohnmobil
  • Heißwasser in 6 Stufen, erhitzt nur die gezapfte Menge
  • Kindersicherung sperrt die heißen Stufen bis zum Druck auf die Lock-Taste
  • Werkzeugloser Filterwechsel per Drehkartusche

Cons

  • Nur 1,7 l pro Tankfüllung, bei 3 l täglich mindestens zweimal nachfüllen
  • 100-°C-Taste liefert am Auslass nur 80 bis 91 °C
  • Pumpe brummt hörbar, auch wenn niemand zapft
  • Außentank tropft beim Herausnehmen und neigt zu Algen
  • Filteranzeige zählt Pumpenlaufzeit, meldet bei wenig Nutzung viel zu spät

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
