Verdict

Pros & cons

Der Coway Airmega 150 ist ein schlichter Luftreiniger für Schlaf- und Arbeitszimmer bis etwa 22 m², der Feinstaub zuverlässig herausfiltert und im Silent-Modus nur 2,6 W braucht. App, Fernbedienung und Timer fehlen, die Automatik regelt über den Feinstaubsensor. Der Haken: Bei einem Teil der Geräte setzt nach einigen Tagen ein hörbares Motorbrummen ein, das gerade nachts stört.

Pros

  • Senkt PM2,5 in 18 m² binnen einer Stunde von 110 auf 7,1 µg/m³
  • Silent-Modus mit 35 bis 40 dB nachts kaum hörbar
  • Sehr sparsam: 2,6 W im Silent-Modus, 0,2 W im Standby
  • Ein Filterset pro Jahr, Aktivkohle in der EU-Version als Granulat
  • Automatik reagiert über PM2,5-Sensor auf Kochen und Deo
  • Ohne Ionisator, also keine Ozonbildung

Cons

  • Bei einem Teil der Geräte Motorbrummen nach einigen Tagen
  • Keine App, keine Fernbedienung, kein Timer
  • Statusleuchte bleibt an, Gerät wird nie ganz dunkel
  • Versprochene 20 dB im Schlafmodus real 35 bis 40 dB
  • Kein Griff, Standfüße ohne Gummierung

Der Levoit Eleva 300X ist ein kompakter Luftreiniger für Schlaf- und Kinderzimmer bis 22 m². Sein Lasersensor regelt zuverlässig nach, und Stufe 3 bleibt unter 45 dB bei rund 195 m³/h. Der Haken: Gegen starke Gerüche hilft er wenig, auf Turbo wird er mit 55 dB laut, und die App braucht ein VeSync-Konto.

Pros

  • Reinigt real rund 280 m³/h, genug für Räume bis 22 m²
  • Stufe 3 mit 44,9 dB schafft noch rund 195 m³/h
  • Lasersensor reagiert schnell und plausibel auf Kochen und Staub
  • HEPA-Filter hält 18 bis 24 Monate, Aktivkohle separat tauschbar
  • Sparsam: 10 W auf Stufe 3, 0,65 W im Standby
  • Display und LED-Ring nachts abschaltbar

Cons

  • Wenig Aktivkohle, starke Gerüche und Möbelausdünstungen bleiben lange
  • Turbostufe mit 55,4 dB laut, über der Angabe von 50 dB
  • App nur mit VeSync-Konto und 2,4-GHz-WLAN, keine lokale Schnittstelle
  • Filterüberwachung nach Nutzung nur mit Originalfiltern per QR-Code
  • Kein Griff, Gehäuse beim Umstellen schlecht zu fassen
