Verdict
Pros & cons
Der Blueair Blue Signature Medium ist ein Luftreiniger und Beistelltisch zugleich. Mit 545 m³/h CADR reinigt er Wohnzimmer von 25 bis 35 m² zügig und braucht dabei nur 36 W. Der Haken: Der Ionisator lässt sich nicht abschalten, und die leiseste Stufe ist lauter als die angegebenen 19 dB. Für ein kleines Schlafzimmer zahlst du für Leistung, die du dort nicht brauchst.
Pros
- 545 m³/h CADR reichen für Wohnzimmer von 25 bis 35 m² mit Reserve
- Dient mit glatter Deckplatte als Beistelltisch neben Sofa oder Sessel
- Sparsam: rund 110 kWh im Jahr bei acht Stunden Volllast täglich
- Filterwechsel ohne Werkzeug in wenigen Minuten
- App mit Zeitplänen, Luftwerte-Verlauf, Alexa und Google Assistant
- Mit 4,3 kg leicht von Raum zu Raum zu tragen
Cons
- Ionisator weder am Gerät noch per App abschaltbar
- Leiseste Stufe deutlich lauter als die angegebenen 19 dB
- Ersatzfilterring ist der größte laufende Kostenfaktor
- Matte Deckplatte bekommt schon früh feine Kratzer
- Clip am neuen Filterring schließt nur fummelig
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
