Verdict
Pros & cons
Die iSpring RCC7AKUV ist eine Untertisch-Osmoseanlage mit 12-l-Tank und Systemzertifikat nach NSF/ANSI 58, die Blei, Fluorid und Nitrat gründlich zurückhält. Sie passt zu Haushalten mit Platz im Spülenschrank, die günstige Standardfilter schätzen und den Einbau selbst angehen. Der Haken: Bei gechlortem Stadtwasser kann die UV-Stufe süßlichen Geruch verursachen, dazu kommen rund 2 l Abwasser je Liter.
Pros
- Blei, Arsen und Uran im Labor um 100 % gesenkt, Fluorid um 99 %
- Systemzertifikat nach NSF/ANSI 58 für 97,9 % weniger gelöste Salze
- Vorfilter in Standardmaß, auch von anderen Herstellern erhältlich
- Mit rund 2 l Abwasser je Liter sparsam für eine Tankanlage ohne Pumpe
- Mechanischer Leckageschutz sperrt den Zulauf bei Nässe
- Ersatzteile vom Kundendienst kommen schnell und oft kostenlos
Cons
- UV-Stufe verursacht bei gechlortem Stadtwasser teils süßlichen Geruch
- Mineralfilter gab im Labor Spuren von Arsen und Vanadium ab
- Undichtigkeiten an Steckverbindern und Winkelstücken kommen wiederholt vor
- Für den US-Markt gebaut: UV-Vorschaltgerät auf 110 V, Anschlüsse in Zoll
- 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
