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 Medify Air MA-40 ist ein reiner Luftreiniger, der Rauch binnen einer Stunde fast vollständig aus der Luft holt und mit 406 m³/h Räume bis rund 30 m² schafft. Allergiker und Haushalte mit offener Küche bekommen viel Reinigung, aber keine Fernbedienung und keine App. Der Haken: Die US-Version braucht 120 V statt 230 V, und selbst im Schlafmodus rauscht er mit rund 50 dB.
Pros
- Rauchtest: PM2,5 sinkt in einer Stunde von 18,3 auf 0,1
- CADR bis 406 m³/h reicht für Räume bis rund 30 m²
- Aktivkohle-Pellets binden Bratgerüche in der offenen Wohnküche
- Ionisator abschaltbar, kein Ozon messbar (0,0 ppm)
- Anzeige abschaltbar, Timer bis 8 h
- Solides Gehäuse, mit gut 7 kg per Griff tragbar
Cons
- US-Version für 120 V, an 230 V geht die Platine kaputt
- Schlafmodus mit 50,4 dB statt angegebener 40,5 dBA klar hörbar
- Keine Fernbedienung und keine App, nur Touchfeld auf dem Deckel
- Garantie verlangt Original-Filterwechsel alle vier bis fünf Monate
- LEDs bei Tageslicht kaum lesbar, Netzkabel kurz
