Verdict

Pros & cons

Der BLUEAIR BLU-110088_1 ist ein schneller, nachts sehr leiser Luftreiniger für Wohn- und Schlafzimmer bis etwa 41 m². Mit 510 m³/h CADR, 23 dB im Nachtmodus und 3,59 kg Gewicht passt er gut zu Allergikern und Tierhaltern. Der Haken: Der Stoffbezug sammelt außen Staub, und der Hauptfilter muss alle sechs bis neun Monate getauscht werden – plane die Folgekosten mit ein.

Pros

  • CADR von 510 m³/h reicht für Räume bis rund 41 m²
  • Nachtmodus mit 23 dB und vollständig gedimmter Beleuchtung
  • Auf höchster Stufe nur 50 dB, für diese Leistung niedrig
  • Feinstaubsensor regelt bei Kochdunst und Rauch schnell nach
  • Mit 3,59 kg leicht zwischen Räumen zu tragen
  • Waschbarer Vorfilter hält Tierhaare und Flusen vom Hauptfilter fern

Cons

  • Stoffbezug sammelt außen Staub und muss regelmäßig abgesaugt werden
  • Hauptfilter alle sechs bis neun Monate fällig
  • Ersatzfilter waren nach Marktstart lange nicht erhältlich
  • Touch-Tasten ohne Druckpunkt reagieren nicht immer beim ersten Antippen
  • Zeitpläne und Filterstand nur per App, keine Fernbedienung

Der Bosch Air 4000i ist ein leiser, sauber verarbeiteter Mittelklasse-Reiniger für Schlaf- und Wohnzimmer bis etwa 24 m². Mit 300 m³/h filtert er zügig, im Ruhemodus läuft er mit rund 34 dB, und die Anzeige lässt sich abschalten. Der Haken: eine App mit wenig Tiefgang, Kopplung nur im 2,4-GHz-WLAN und ein Sensor, der entfernte Rauchquellen übersieht.

Pros

  • Ruhemodus mit knapp 34 dB und abgeschaltetem Leuchtring, gut fürs Schlafzimmer
  • CADR von 300 m³/h reinigt Räume bis 24 m² zügig
  • Sensor reagiert auf direkten Rauch nach 9 Sekunden, Werte nah am Referenzgerät
  • Höchste Stufe mit 53 dB vergleichsweise leise
  • Matter-zertifiziert, lokal in Home Assistant und Apple Home steuerbar
  • Geringer Stromverbrauch mit 26 W, Filter hält rund 12 Monate

Cons

  • Sensor übersieht schwache Quellen wie ein Räucherstäbchen in 1 m Abstand
  • App ohne Feinstaubverlauf und Warnung, Konto und 2,4-GHz-WLAN nötig
  • Feste Lüfterstufen, Wechsel der Automatik sind hörbar
  • Kombifilter muss komplett raus, wenn die Aktivkohle gesättigt ist
  • Filterwechsel über den Boden, Gerät muss dafür auf den Kopf
