Verdict
Pros & cons
Die OsmoFresh Fusion Air ist ein Auftischgerät ohne Installation, das Leitungswasser zuverlässig weich und mild filtert. Für Singles und Paare in Mietwohnung oder Büro taugt sie gut, auch für Tee per Flex-Taste. Der Haken: Statt 95 °C kommen meist nur rund 80 °C an, vorher läuft kühles Wasser nach. Dazu muss der 4,7-l-Tank jedes Mal ganz geleert werden, und die Herstellerkartuschen sind teuer.
Pros
- Weiches, remineralisiertes Wasser mit 2,5 °dH, Kalkränder im Wasserkocher bleiben aus
- Keine Installation nötig, nach rund 20 Minuten startklar
- Flex-Taste mit 40 bis 90 °C in 5-Grad-Schritten für Tee
- Abwasserverhältnis 2:1, halb so viel Abwasser wie beim Vorgänger
- Werkzeugloser Filterwechsel in etwa 5 Minuten mit Wechselanzeige
- UV-C-LEDs in Innentank und Auslass, Standby unter 0,5 W
Cons
- Heißwasser kommt mit rund 80 °C statt 95 °C an, erst nach 5 s Vorlauf
- Tank muss nach etwa 2 l jedes Mal komplett geleert und neu befüllt werden
- Nach Heißwasser läuft an ungesperrter Taste kurz heißes Wasser nach
- Nur teure Herstellerkartuschen, Standardfilter passen nicht
- Tankdeckel und Haken verklemmen leicht, Anschlüsse tropfen beim Tragen
Die Philips 6100 Umkehrosmose ist ein Auftischgerät mit Heißwasser, das gründlich entkalkt und filtert: Die Härte sank am Schwestermodell von 94 auf 12 ppm. Sinnvoll ist sie für dich bei hartem Wasser und einzelnen Tassen Tee oder Kaffee. Der Haken: Verarbeitung und Haltbarkeit überzeugen nicht, kochend heiß wird das Wasser nicht, und das Gerät hängt an einer herstellereigenen Kartusche.
Pros
- Senkt die Wasserhärte deutlich, am Schwestermodell von 94 auf 12 ppm
- Heißwasser in wenigen Sekunden per 2400-W-Durchlauferhitzer, vier Temperaturstufen
- Ohne Installation, braucht nur Steckdose und 20 x 30,2 cm Stellfläche
- Sparsames Verhältnis von Reinwasser zu Abwasser von 3:1
- Kartusche ohne Werkzeug wechselbar, Display zeigt Wechsel an
- Leiser Betrieb im Alltag
Cons
- Mehrere Ausfälle, Lecks und Fehlercodes im ersten Betriebsjahr, Service zäh
- Wasser bleibt trotz 99-°C-Stufe unter dem Siedepunkt
- Etwa ein Drittel des 4-l-Nachfülltanks bleibt ungenutzt
- Nur herstellereigene Kartusche ADD541RO passt, Lieferbarkeit war anfangs holprig
- Enge Tassenmulde, hohe Becher passen nicht, Wasser spritzt
