Verdict
Pros & cons
Die iSpring RCC7AK ist eine klassische Untertischanlage mit Vorratstank, die Blei, Uran und Nitrat gründlich aus dem Wasser holt und dank Standardfiltern niedrige Folgekosten hat. Sie passt zu Haushalten mit hartem Wasser, alten Leitungen und viel Platz im Spülenschrank. Der Haken: 2,1 bis 2,5 l Abwasser je Liter, ein langsam füllender Tank und ein mitgelieferter Hahn, der oft tropft.
Pros
- Entfernt Blei, Arsen, Uran und Mikroplastik im Labor zu 100 %
- Senkt Fluorid um 87 bis 99 % und Nitrat um 85 bis 95 %
- Gelöste Salze sinken von 635 auf 44 ppm
- Systemzertifikat nach NSF/ANSI 58 für die ganze Anlage
- Niedrige Filterkosten durch Standardkartuschen, Membran hält 36 Monate
- Läuft ohne Strom, Boosterpumpe bei Bedarf nachrüstbar
Cons
- 2,1 bis 2,5 l Abwasser je Liter Trinkwasser ohne Pumpe
- Mitgelieferter Hahn tropft und sitzt locker, auch Steckverbindungen lecken
- Tank füllt sich langsam, rund 134 statt 284 l am Tag
- T-Stück passt nicht ans deutsche Eckventil, Adapter auf G 3/8 nötig
- Filterwechsel nur mit Schlüssel, ohne Wechselanzeige
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
