Verdict

Pros & cons

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

Der Levoit Core 600S ist ein reiner Luftreiniger für große Räume, der Rauch und Feinstaub ungewöhnlich schnell aus der Luft holt: Mit 697 m³/h reicht er für Räume bis etwa 56 m². Für offene Wohnküchen, Raucher und Tierhalter passt er gut. Der Haken sind die laute obere Stufen und zwei teure Originalfilter im Jahr. Unter 45 dB(A) bleiben nur rund 265 m³/h.

Pros

  • Rauchkammer nach 6 min auf 9 µg/m³ Feinstaub gesenkt
  • 697 m³/h reichen für Räume bis rund 56 m²
  • Automatik reagiert schnell auf Bratdunst und Zigarettenrauch
  • Sparsam: rund 5 W im Schlafmodus, knapp 11 W auf Stufe 2
  • Display abschaltbar, Lichterkennung bremst die Automatik nachts
  • App mit Zeitplänen und mehreren Automatikvarianten läuft zuverlässig

Cons

  • Ab Stufe 3 rund 54 dB(A), Turbo bis 62 dB(A)
  • Unter 45 dB(A) bleiben nur rund 265 m³/h
  • Kombifilter nicht teilbar, im Dauerbetrieb zwei Originale pro Jahr
  • Sensor erfasst keine Gerüche, Kochgeruch ohne Dunst bleibt unbemerkt
  • Auf einzelnen Stufen leises Surren oder Pfeifen
