Verdict

Pros & cons

Der Leitz TruSens Z-1000 ist ein kompakter Luftreiniger ohne Sensor, der Feinstaub auf Turbo um 93 % senkt. Mit 95 m³/h CADR reicht er realistisch nur für knapp 8 m². Schon Stufe 1 misst 43,8 dB und pfeift hörbar, ein Nachtmodus fehlt – fürs Schlafzimmer taugt er nicht, gegen Kochgerüche hilft die dünne Aktivkohle kaum.

Pros

  • Senkt Feinstaub PM2,5 in 18 m² binnen einer Stunde um 93 %
  • Kompakt mit 3,5 kg und Griff im Deckel zum Umtragen
  • Sparsam: 9,4 W auf Stufe 1, 0,2 W im Standby
  • Filterwechsel in rund 5 min ohne Werkzeug
  • Eigene Wechselanzeige für jedes Verschleißteil

Cons

  • Schon Stufe 1 mit 43,8 dB und hohem Pfeifton zu laut fürs Schlafzimmer
  • CADR von 95 m³/h reicht realistisch nur für knapp 8 m²
  • Dünne Aktivkohleschicht bindet Kochgerüche kaum
  • Kein Sensor, keine Automatik, kein Timer, kein Nachtmodus
  • Leuchten nicht abschaltbar, nach Stromausfall bleibt das Gerät aus

Der Winix Zero ist ein reiner Luftreiniger mit H13-Filter und Aktivkohle, der Räume bis etwa 31 m² zuverlässig von Staub und Pollen befreit. Der Sensor reagiert nach wenigen Sekunden auf Rauch. Der Haken liegt im Schlafzimmer: Signaltöne und Anzeige stören nachts, und bei gedämpftem Licht schaltet die Automatik in den Schlafmodus und filtert kaum noch.

Pros

  • 390 m³/h CADR reichen realistisch für Räume bis etwa 31 m²
  • Partikelsensor reagiert nach wenigen Sekunden auf Staub und Rauch
  • Schlafmodus mit rund 27 dB kaum hörbar
  • Ein kompletter Filtersatz für das erste Jahr liegt bei
  • Große, eindeutige Tasten ohne Untermenüs
  • PlasmaWave-Ionisator lässt sich abschalten

Cons

  • Signaltöne lassen sich nicht abschalten, jeder Tastendruck piept
  • Anzeige erlischt nur im Schlafmodus, Sleep-LED bleibt an
  • Automatik wechselt bei gedämpftem Licht in den Schlafmodus und filtert kaum
  • Dünne Kohlematte hält starke Gerüche kaum zurück
  • Kohlefilter alle 3 Monate, Ersatzfilter sind der größte Kostenpunkt
