Verdict

Pros & cons

Der Dyson Purifier Hot+Cool HP1 ist ein Kombigerät aus Luftreiniger, Heizlüfter und Ventilator für Räume bis etwa 20 m². Er heizt ein kaltes Zimmer in Minuten und holt Rauch zügig aus der Luft. Gerüche erkennt kein Sensor, und beim Kühlen bleibt nur Luftzug. Lohnend ist er für dich, wenn du alle drei Funktionen übers Jahr nutzt, als reiner Luftreiniger zu teuer.

Pros

  • Heizt einen Raum in fünf Minuten von 18 auf 24 °C
  • Rauch und Feinstaub sind in rund drei Minuten aus der Luft
  • Untere Stufen leise, Nachtmodus stört auch empfindliche Schläfer nicht
  • Einfache Bedienung, magnetische Fernbedienung haftet am Ring
  • Schwenkung bis 350° mit Richtungswahl in der App
  • App zeigt PM2,5, PM10 und Temperatur als Verlauf

Cons

  • Kühlt nur per Luftzug, die Raumtemperatur sinkt kaum
  • Kein Gas- oder Geruchssensor, Automatik ignoriert Kochdunst
  • Aktivkohle bindet Gerüche von Angebratenem nicht zuverlässig
  • Auf höchster Stufe 63 dB, die braucht der Ventilator zum Kühlen
  • App-Verbindung reißt zeitweise ab, Konto ist Pflicht

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
