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 Philips PureProtect 3200 ist ein reiner HEPA-Luftreiniger mit zwei Lüftern, der Räume bis etwa 35 m² schnell und leise reinigt: Unter 45 dB schafft er noch rund 290 m³/h. Für Schlafzimmer und Tierhaushalte taugt er gut, die App ist durchdacht. Der Haken: Der PM2,5-Sensor misst unzuverlässig, und gegen Koch- und Schweißgerüche hilft die Aktivkohle nur wenig.
Pros
- Unter 45 dB noch rund 290 m³/h, genug für 20 bis 23 m²
- Nebel im 50-m²-Studio nach 33 Minuten beseitigt
- Auf Turbo mit 53 bis 56 dB vergleichsweise leise
- Sparsam: 12,6 W auf mittlerer Stufe, 1,1 W im Standby
- Lichter komplett abschaltbar, Allergy-Sleep-Modus regelt nachts leise nach
- App mit Zeitplänen, Verlauf und Sprachsteuerung per Alexa und Google
Cons
- PM2,5-Sensor zeigt sprunghafte und teils falsche Werte
- Bindet Koch-, Schweiß- und Uringerüche nur schwach
- Verklebte Filter werden komplett getauscht, nicht waschbar
- Kein Tragegriff, 6,2 kg mühsam umzustellen
- Sensortasten erlöschen nach einer Minute, im Sonnenlicht schwer lesbar
