Grandbreeze 14000 BTU mobile air conditioner

When summer turns your living room into a furnace and your bedroom into somewhere you'd rather not be, the Klarstein Grandbreeze is the answer. No installation, no engineers, no fuss — just plug in, connect the exhaust hose, and cool down rooms up to 65 m².

At 14,000 BTU and 4.1 kW, this is serious cooling power for larger spaces: open-plan living areas, home offices, and bigger bedrooms all fall well within its 46–65 m² sweet spot. Energy efficiency class A and a power draw of just 1.5 kWh per hour mean you're not paying through the nose to stay comfortable — standby consumption drops to a mere 0.5 W. Set your ideal temperature anywhere between 18 and 32 °C, choose from three fan speeds, and let the automatic vertical louvre swing distribute cool air evenly across the room. Airflow reaches 390 m³/h, so even larger spaces feel the benefit quickly.

The Grandbreeze does the job of three appliances: air conditioner, fan, and dehumidifier — all in one unit. The built-in dust filter keeps the air clean, and the dehumidifier removes up to 1.95 litres of moisture per hour. The 0.8-litre water tank handles this automatically and comes with a water level indicator so you always know when it needs emptying. A 24-hour timer and a dedicated Night Mode let you set everything in advance and sleep through it undisturbed.

Smart home ready from the moment you switch it on. The Klarstein app gives you full control from your phone — adjust the temperature, switch modes, or set a timer from the sofa or on your commute home. Amazon Alexa and Google Home are fully integrated, so a quick voice command is all it takes. Programme the Grandbreeze to start cooling before you get back, so the flat is already comfortable when you walk through the door. The unit uses R290 refrigerant, which has a low global warming potential and is among the more energy-efficient choices in its class.

Built for spaces where a fixed air con simply isn't an option — rented flats, offices, hotel rooms — the Grandbreeze rolls wherever you need it on lockable castors that work on any floor surface. The telescopic exhaust hose and window sealing kit are both included in the box, so you're set up and cooling in minutes.

Stay cool this summer — order the Grandbreeze today and enjoy comfortable temperatures right through to autumn.
