Verdict

Pros & cons

Der Dyson Hushjet Compact ist ein sehr leiser Luftreiniger fürs Schlafzimmer, der auf den unteren Stufen um 36 dB bleibt und höchstens 18,6 W zieht. Mit rund 270 m³/h reicht er nur für Räume bis etwa 22 m², die beworbenen 100 m² sind reine Rechnung. Dazu kommen ein träger Sensor, der nur Feinstaub misst, und eine kleine Kohlefüllung. Du zahlst vor allem für Form und Ruhe.

Pros

  • Auf unteren Stufen und im Nachtmodus nur rund 36 bis 37 dB
  • Sparsam: 1,8 W auf Stufe 1, 18,6 W auf höchster Stufe
  • Partikelfilter hält bis zu fünf Jahre, Kohlefilter getrennt tauschbar
  • Feinstaubwerte im Display liegen nah an externen Messgeräten
  • Kleiner Raum mit Rauch nach 37 min wieder sauber
  • Steht stabil und kippt beim Anstoßen nicht

Cons

  • Reinigungsleistung von rund 270 m³/h reicht nur für etwa 22 m²
  • Sensor reagiert träge, erste Anzeige erst nach 38 s
  • Nur 120 g Aktivkohle, gegen starke Ausdünstungen kaum wirksam
  • Volle Bedienung nur per App mit Konto, keine gedruckte Anleitung
  • Düse aus dünnem Kunststoff mit sichtbaren Produktionsresten

Der Sandrem Ganymede-EJH300-D-06 ist ein reiner Luftreiniger mit H13-Filter und Feinstaubsensor. Er reicht für ein Schlafzimmer bis 24 m², im Schlafmodus bleibt er leise unter 30 dB. Die beworbenen 60 bis 90 m² sind deutlich zu hoch angesetzt. Ob sich der Ionisator abschalten lässt, ist offen. Wer Ionisator und UV-Licht meiden will, sollte das vor dem Kauf klären.

Pros

  • Schlafmodus unter 30 dB, gleichmäßiges Rauschen ohne Brummen
  • 300 m³/h CADR reicht für Räume bis etwa 24 m²
  • PM2,5-Automatik regelt nach dem Kochen zügig hoch
  • Mit 3,5 kg leicht von Raum zu Raum zu tragen
  • App mit Verlauf der Luftwerte, Timer bis 24 h
  • Höchstens 32 W, rund 93 kWh im Jahr bei 8 h Volllast

Cons

  • Raumangabe von 60 bis 90 m² ist weit überzogen
  • Neuer Filter riecht anfangs nach Kunststoff
  • Ob die UV-C-Lampe arbeitet, ist von außen nicht erkennbar
  • Auf schmalem Nachttisch sperriger, als die Produktfotos zeigen
