Breeze Box mobile air conditioner 11000 BTU

When the British summer actually delivers — or you're working through a stuffy office afternoon — the Klarstein Breeze Box keeps things cool without the faff of fixed installation. Just position it, route the telescopic exhaust hose to the window, and you're away. No engineers, no drilling, no drama.

With 11,000 BTU / 3.2 kW of cooling power, the Breeze Box handles rooms from 37–51 m² with ease. It's a genuine 3-in-1 unit: portable air conditioner, fan, and dehumidifier in a single compact housing. You set the temperature anywhere between 18 and 32 °C — dial it in to exactly where you're comfortable. Energy efficiency class A means it won't cause bill shock even running through a warm spell, and at a maximum of 65 dB with a dedicated night mode, it's quiet enough for the bedroom as well as the living room.

Control everything from the Klarstein app — temperature, mode, timer, and device status, whether you're at home or still at your desk. Already got Alexa or Google Home set up? The Breeze Box works with both, so you can adjust the temperature by voice without touching your phone. The R290 refrigerant compressor operates with a particularly low global warming potential. The included telescopic exhaust hose and window sealing kit mean you can get started straight away. Set the 24-hour timer to have your room cooled down before you walk through the door.

The Breeze Box fits seamlessly into any smart home setup and is well-suited to larger living spaces, open-plan flats, home offices, and hotel rooms up to 51 m². If you've been putting up with a fan that just moves warm air around, this is a proper step up.

Stay cool this summer — order the Klarstein Breeze Box and get the temperature where you want it, all season long.
