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 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
