Verdict
Pros & cons
Der Philips PureProtect Lite 700 ist ein leiser Luftreiniger fürs Schlafzimmer: Mit 180 m³/h reinigt er Räume bis etwa 14 m² gründlich, die Schlafstufe liegt bei 11 dB. Der Filter hält bis zu 36 Monate. Der Haken: Es gibt keinen Sensor und keine Automatik, und für ein Wohnzimmer reicht die Luftleistung nicht – die 75 m² auf dem Karton führen in die Irre.
Pros
- Schlafstufe mit 11 dB, auch auf Turbo nur 42 dB
- Filter FY0700 hält bis zu 36 Monate
- Zieht höchstens 14 W, sparsam im Dauerbetrieb
- Lichtring dimmt sich selbst und lässt sich ganz abschalten
- ECARF-Siegel, Filter mit Pollen und Milbenallergenen geprüft
- Kompakt mit 22,2 x 22,2 cm Grundfläche und 2,16 kg
Cons
- Kein Luftqualitätssensor, daher keine Automatik
- 180 m³/h reichen nur für etwa 14 m², nicht 75 m²
- Timer, Zeitplan und Kindersicherung nur per App
- App-Kopplung nur im 2,4-GHz-WLAN
- Dünne Aktivkohle hilft kaum gegen Bratdunst oder Rauch
Der Soehnle AirFresh Clean 400 ist ein schlanker HEPA-Luftreiniger, der auf Stufe I mit 30 dB leise genug fürs Schlafzimmer bleibt. Er taugt für Schlaf-, Kinder- und Arbeitszimmer bis etwa 20 m², nicht für die beworbenen 38 m². Der Haken: Soehnle nennt keinen Luftdurchsatz, Automatik und Nachtmodus laufen nicht gleichzeitig, und hartnäckige Gerüche bleiben teilweise stehen.
Pros
- Auf Stufe I höchstens 30 dB, bis Stufe II sehr leise
- Nachtmodus schaltet alle Leuchten nach 10 Sekunden ab
- PM2,5-Automatik regelt bei Bratdunst und Zigarettenrauch hoch
- H13-Filter mit ECARF-Siegel, spürbar bessere Luft in der Pollensaison
- Mit 2,8 kg und 23 cm Durchmesser leicht umzustellen
- Geringer Stromverbrauch, 6 bis 10 W bis Stufe III
Cons
- Kein Luftdurchsatz angegeben, beworbene 38 m² unbelegt
- Automatik und Nachtmodus nicht gleichzeitig nutzbar
- Hartnäckige Raumgerüche verschwinden nur teilweise
- Farbring bei Tageslicht schlecht ablesbar, keine Zahlenanzeige
- Keine App, keine Fernbedienung, nur vier Tasten am Gerät
