Cools rooms that other portables struggle with: With 12,000 BTU of cooling power and energy efficiency class A+, the Grandbreeze handles spaces up to 56 m² — all for just 1.1 kWh per hour.
Air conditioning, fan, and dehumidifier — all in one: Switch between air conditioning, fan-only, and dehumidifier mode as the day demands — no need for separate devices cluttering your space.
Voice and app control from anywhere: Fully compatible with Amazon Alexa and Google Home, the Grandbreeze responds to voice commands and connects to the Klarstein app — so you can set the temperature before you've even left the office.
Uninterrupted sleep on hot nights: Night Mode automatically adjusts cooling output and runs at a maximum of 65 dB — quiet enough for bedrooms so you wake up rested, not groggy.
No installation, no hassle: The telescopic exhaust hose and window sealing kit are included, and lockable castors let you roll the Grandbreeze from room to room in seconds — no engineer, no drill, no delay.
Product description
Summer in the UK might not always be blazing, but when the heat hits — a stuffy bedroom at midnight, a home office that turns into a greenhouse by 2pm — you need something that actually works. The Klarstein Grandbreeze is a portable air conditioner built for bigger spaces: rooms up to 56 m² cool down to a temperature you choose, no installation, no engineer, no fuss.
At 12,000 BTU (3.5 kW), this is serious cooling power. Energy efficiency class A+ keeps running costs in check at just 1.1 kWh per hour, with a standby draw of only 0.5 W. An airflow of 390 m³/h pushes cool air right across the room, and the automatic vertical louvre sweep ensures it reaches every corner. Set your preferred temperature anywhere between 18 and 32 °C, choose from three fan speeds, and let the Grandbreeze do the rest.
It's a 3-in-1 unit: air conditioner, fan, and dehumidifier in a single device. The dehumidifier pulls up to 1.5 l/h of moisture from the air — useful during those muggy British summers — and the 0.8-litre water tank handles it automatically until it reaches capacity, with a water-level indicator so you're never caught off guard. A built-in dust filter keeps the air clean, and the 24-hour timer and Night Mode mean the Grandbreeze adapts to your day without any input from you.
Control it however suits you. The Klarstein app lets you adjust temperature, mode, and timer from your phone — handy for getting the living room cool before you even walk through the door. Amazon Alexa and Google Home are fully supported, so a quick voice command is all it takes. The R290 refrigerant used has a low global warming potential and is among the more energy-efficient choices in its appliance class.
The Grandbreeze is designed for flats, home offices, and hotel rooms in the 42–56 m² range — anywhere a fixed air conditioning system isn't an option. The telescopic exhaust hose and window sealing kit are included in the box, and the lockable castors roll smoothly across any floor surface, so moving it from room to room takes seconds.
Stay cool this summer with the Klarstein Grandbreeze — order yours today and enjoy your home at the right temperature, whatever the weather throws at you.
