Verdict
Pros & cons
Der Philips PureProtect 4200 ist ein kompakter, reiner Luftreiniger, der mit 600 m³/h Wohnzimmer bis 48 m² gründlich reinigt. Die von Philips angegebenen 156 m² sind unrealistisch. Bei Staub und Tierhaaren leistet er gute Arbeit, bei Gerüchen weniger. Der Haken: Er braucht jedes Jahr ein neues Filterpaar, sonst sperrt sich das Gerät, und nachts surrt der kleine Lüfter hörbar.
Pros
- 600 m³/h CADR auf nur 28,5 x 28,5 cm Grundfläche
- Reinigt Wohnräume bis 48 m² mit fünf Luftwechseln pro Stunde
- PM2,5-Sensor reagiert schnell, etwa beim Kochen in der offenen Küche
- Höchste Stufe mit 51,5 dB für diese Leistung vergleichsweise leise
- Senkt Staub und Tierhaare im Dauerbetrieb sichtbar
- Leuchten und Display komplett abschaltbar
Cons
- Kleiner Lüfter surrt nachts hoch, ab mittlerer Stufe zu laut zum Schlafen
- Ohne jährlichen Wechsel des Filterpaars sperrt sich das Gerät
- Unterer Filter knapp über dem Boden wirbelt Staub auf
- App-Kopplung scheitert teils, nur 2,4-GHz-WLAN
- Aktivkohle bindet Gerüche nicht in jedem Haushalt zuverlässig
Der Xiaomi Smart Air Purifier Elite ist ein solider Luftreiniger für große Wohnräume: Mit real rund 510 m³/h reinigt er Räume bis etwa 40 bis 48 m² und bindet Gerüche dank viel Aktivkohle zügig. Der Haken: Unter 45 dB schafft er nicht mehr als der 4 Pro, die Automatik regelt spät hoch, und ohne App und Konto kommst du über die Grundfunktionen kaum hinaus.
Pros
- Real rund 510 m³/h, genug für Wohnzimmer bis etwa 40 bis 48 m²
- Viel Aktivkohle mit 135 m³/h Formaldehyd-CADR, Kochgerüche schnell weg
- Auf Stufe 1 etwa 30 dB, Display ganz abschaltbar
- Filter hält rund 10 Monate, RFID-Chip erkennt Wechsel automatisch
- Ionisator und UV-C-Diode direkt am Gerät abschaltbar
- Sparsam mit 60 W Volllast und 2 W Standby
Cons
- Unter 45 dB nur rund 295 m³/h, nicht mehr als der 4 Pro
- Automatikmodus regelt nach Kochen oder Lüften erst spät hoch
- Zeitpläne, manueller Modus und Regeln nur per App mit Konto
- 3-in-1-Filter nur als Ganzes tauschbar, Ersatz nicht billig
- PM2,5-Anzeige weicht stark von Vergleichsgeräten ab, eher Trendwert
