Verdict
Pros & cons
Der Coway Airmega 100 ist ein sparsamer Feinstaubfilter für kleine Räume: In 18 m² senkt er den Feinstaub in einer Stunde um 93 % und zieht dabei höchstens rund 23 W. Für Schlaf- und Kinderzimmer bis etwa 20 m² taugt er gut. Der Haken: gegen Küchendunst hilft er kaum, und einzelne Exemplare fallen durch Schleif- oder Sirrgeräusche des Lüfters auf.
Pros
- Senkt Feinstaub in 18 m² binnen einer Stunde um 93 %
- Sehr sparsam: 23 W auf Höchststufe, 0,3 W im Standby
- Partikelsensor reagiert innerhalb von fünf Sekunden
- Schlafmodus mit 35,6 bis 40,3 dB leise genug fürs Schlafzimmer
- Bedienung ohne App, Konto und WLAN
- Günstiger Ersatzfilter, Wechsel ohne Werkzeug
Cons
- Dünne Kohleschicht hilft kaum gegen Kochdunst und Möbelausdünstungen
- Einzelne Geräte mit Schleif- oder Sirrgeräusch des Lüfters
- Beworbene 20 dB erreicht keine Messung
- Unter 45 dB bewegt nur Stufe 1 genug Luft
- Tastensperre löst sich nach Stromtrennung oder Timer-Ende
Der Levoit Core 400S holt Feinstaub und Rauch zügig aus Räumen bis 32 m² und braucht dafür wenig Strom. Die Automatik reagiert schnell, App und Zeitpläne sind ausgereift. In Deutschland gibt es die gedrosselte EU-Version, und die 83 m² auf dem Karton sind unrealistisch. Der Haken ist der nicht waschbare Kombifilter: Läuft das Gerät täglich lange, brauchst du zwei Filter im Jahr.
Pros
- Senkt Feinstaub in 60 Minuten um 96 % in einem 30-m²-Raum
- Laser-Sensor schaltet bei Rauch fast sofort hoch
- Sparsam mit 23 W auf Turbo und 0,9 W im Standby
- Stufe 2 bleibt unter 45 dB(A), Nachtmodus um 25 dB(A)
- App mit Zeitplänen, Timer bis 24 h und Wochenverlauf der Luftwerte
- Filterwechsel ohne Werkzeug in rund zehn Minuten
Cons
- Kombifilter nicht waschbar, bei Dauerbetrieb nach sechs Monaten fällig
- EU-Version gedrosselt auf 400 statt 442 m³/h
- Angegebene 83 m² unrealistisch, real rund 32 m²
- Sensor erkennt keine Gase und Gerüche, hält Befeuchternebel für Feinstaub
- Standard-Aktivkohle zu knapp für Zigarettenrauch in Dauerschleife
