Verdict

Pros & cons

Die iSpring RCD100-E bringt Umkehrosmose ohne jede Installation in die Küche: Tank von Hand füllen, Stecker rein, fertig. Sie hält 97,6 % der gelösten Salze zurück und liefert Heißwasser bis 96 °C für Tee, Kaffee und Fläschchen. Gekühltes Wasser gibt es nicht. Der Haken ist die anfällige Steuerelektronik, die bei mehreren Geräten im ersten Jahr ausfiel – heb den Kaufbeleg gut auf.

Pros

  • Keine Installation nötig, nur Steckdose und Stellfläche von 39 x 18 cm
  • Hält 97,6 % der gelösten Salze und damit Kalk zurück
  • Vier Temperaturstufen bis 96 °C ersetzen den Wasserkocher
  • Sparsames Verhältnis von 2,5 l Reinwasser zu 1 l Konzentrat
  • Werkzeugloser Filterwechsel mit Wechselanzeige im Display
  • Kindersicherung an der Heißwasserausgabe

Cons

  • Steuerelektronik fiel bei mehreren Geräten nach vier bis zwölf Monaten aus
  • Nur herstellereigene Kartuschen, Standardfilter passen nicht
  • Kein gekühltes Wasser und keine Stufe um 70 bis 80 °C für grünen Tee
  • Tank muss von Hand befüllt und Konzentrat geleert werden
  • Garantie nur 1 Jahr

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
