Product description

Summer in the UK might be short — but when a heatwave hits, your bedroom, home office, or living room can become genuinely unbearable. The Klarstein Breeze Box 9k cools rooms up to 33 m² quickly and reliably, with no installation, no drilling, and no engineer needed.

It's a 3-in-1 unit that handles air conditioning, fan mode, and dehumidifying in a single compact appliance. Set your preferred temperature anywhere between 18 and 32 °C with precise, stepless control. Thanks to energy efficiency class A, it uses up to 30% less electricity than lower-rated units — so it won't make your energy bill wince even during a prolonged hot spell.

The Klarstein App gives you full control from your phone: adjust the temperature, switch modes, set a timer, or check the device status at a glance. The Breeze Box 9k also works seamlessly with Amazon Alexa and Google Home, so you can manage it entirely by voice. Setup is straightforward — simply attach the included telescopic exhaust hose and window sealing kit, and you're ready to go. The 24-hour timer and night mode let the unit adapt automatically to your routine. The refrigerant used is R290, which has a low global warming potential.

Heading home after a long day? Open the app before you leave, switch on the cooling, and walk into a room that's already at the right temperature. The Breeze Box 9k integrates naturally into existing Alexa or Google Home setups — and it's equally at home in a hotel room or office up to 33 m².

9,000 BTU, 3-in-1 functionality, energy efficiency class A, and full smart home compatibility — all in a portable unit you can move wherever it's needed. Stay cool this summer with the Breeze Box 9k.

Die Medien konnten nicht geladen werden. We ordered this after chatting to a family member who has the same make. Our daughter’s bedroom gets extremely hot over the summer and so they struggle to sleep. This is perfect! Cools the room down so well, it can be quite noisy but has a mode where it’s better at night and it doesn’t keep us away. Easy to set up and easy to function. My partner has connected to his phone so can control and turn it on before we arrive home. The size is big for our bedrooms but we can cope for the limited summer days we have in the UK.

Die Klimanlage schaffte es nicht 45 qm unter 28 Grad trotz 12 Stunden dauerbetrieb (Außen 35-28 Grad) zu bekommen. Selbst das Schlafzimmer von 12 qm hat die Klima nach 2 Stunden betrieb gerade mal auf 25 Grad runtergekühlt.
Wollte das Gerät nach 21 Tagen dann beim Hersteller gegen ein Gerät mit mehr Leistung tauschen.
Der Händler hat dann gemeint das geht nicht und angeboten das Gerät zu reparieren falls da was kaputt gewesen sein sollte.
Das Gerät musste ich dann selbst zur nächsten Post transportieren, da der Hersteller keine Abholung vereinbart hat.
Ich habe nun das Geld zurückerhalten ohne Kommentar ob und was Defekt war, daher 2 Sterne falls die Klima defekt war. Ansonsten nur ein Stern

Il est malheureux trop bruyant à mon goût, quand il est en route on ne peut pas avoir de discution ou regarder la télévision à côté.
Pour mon appartement de 50m2 c'est un peu juste également je trouve. Il n'arrive pas à descendre la température à moins de 30C lorsqu'il fait 35 Chez moi.
Sinon il est très facile d'utilisation.

Das größte Manko dieses Gerätes ist, dass es, egal ob nur Lüften oder gar Kühlen, für den Betrieb in einem Schlafraum zu laut ist. Die Kühlleistung ist recht gut, mir persönlich fehlt ein Schlauchanschluß auch für die kühle Luft.

Verified review 19/07/2025

Plus: Kühlleistung sehr gut, Entfeuchtungsmodus kühl auch verdammt gut ab Mit gelieferte abfuhrschlauch ist einfach zu installieren und zu bewegen

Minus: schon laut wenn der Kühler an ist die zwei Stöpsel um den Wassertank zu leeren sind entweder zu tief um eine schale drunter zu liegen und der zweite ist zu hoch und direkt über das Stromkabel

Für denn preis denn ich es gekauft habe (236 Euro) sehr zufrieden mit das gerät

Verified review 17/06/2025

Das Teil ist super. Preis Top. Aber: Benutzerhandbuch ist der absolute Horror was das anbringen der Fensterdichtung angeht. Usability fail. Aber ich bin happy über die Kühlung
