Top features

  • Powerful enough for larger rooms: With 14,000 BTU and energy efficiency class A, the Grandbreeze keeps spaces up to 65 m² at your chosen temperature — drawing just 1.5 kWh per hour to do it.

  • One unit, complete room climate control: Switch between cooling, dehumidifying, and fan modes without needing a separate device for each — the Grandbreeze handles your entire room climate in one go.

  • Smart control from anywhere: The Klarstein app and full compatibility with Amazon Alexa and Google Home mean you can adjust the temperature, change modes, or set a timer by voice or from your phone — even when you're not home.

  • Uninterrupted sleep on hot nights: Night Mode adjusts the cooling output automatically and keeps noise to a maximum of 64 dB — quiet enough to run in the bedroom without disturbing your sleep.

  • Keeps the air clean as it cools: The built-in dust filter removes airborne particles as the unit runs, while the dehumidifier draws out up to 1.95 litres of moisture per hour — so the air in your room stays fresh as well as cool.

Product description

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.

Klarstein Grandbreeze Smart Potable Air Conditioner 16000 BTU Beast Of A Cooling Machine!!!

I already had a DeLonghi portable air conditioner with 11,500k BTU cooling capacity which I regularly move from my living room to my bedroom every night during the heatwave seasons which unfortunately not powerful enough for my 270sq ft living room but perfect for my 168sq ft bedroom.

I now recently bought the Klarstein Grandbreeze Smart 16000 BTU Portable Air Conditioner Black to use in my living room only. After using this for a couple of hours, it chills like a pro! Dropped 28°C to 22°C in 20 mins on High, so cooling is top-notch. The 16k BTU output is no joke — it’s a proper unit.

Noise is where placement matters:
- On High @ 1m = 61 dB (like a fridge + fan).
- On Low @ 1m = 58dB also (like a fridge + fan).
- On Sleep mode = 48-50 dB (library quiet).

Pros:
- Serious cooling power for the price — chills a 30m² room no problem_
- App control + WiFi works well from Cheltenham to phone abroad_
- Build feels sturdy (vs cheaper 12k models)
- Comes with decent window kit + remote
- Drainage is easy via hose tap_
- Timer + multiple modes (Eco/Turbo/Sleep)

Cons:
- Hose is short (1.5m), don’t expect to move it far from window.
- No condensation tank level indicator (just a red light when it’s full)
- Klarstein’s UK support is email and live chat on website only (no phone help)

Overall: If you’ve got space + position it right, this is a beast. 5 stars from me *****

Die Anlage wird über einen unseriösen Versanddienstleister versendet "trans-o-flex Express GmbH" wo mir einfach jeden Tag der Aktuelle Tag als Liefertag angezeigt wird. Die Telefonnummer auf der Klarstein.de Rechnung exestiert nicht. Der Kundenchat hat nur einen Bot der Rückrufe anbietet die es wiederrum nicht gibt. Seriös sieht anders aus.

Die Kühlleistung der Klimaanlage ist meiner Meinung nach doch sehr ordentlich. Bei meiner offenen Dachgeschoss Wohnung 58 qm Fläche ( mit teil offenem Deckenbereich zur Dachgaube hin ) lag die Innenraumtemperatir bei 34°. Die Klimanlage hat es relativ zügig geschafft auf 30° runter zu kühlen ( bei 39° Außentemperatur wohl gemerkt und meine Wohnung war mit einer Wärmelast schon vorbelastet durch die 34° ). Die Klimaanlage war dann auch sehr gut in der Lage die 30° zu halten bis zum Ende des Abends. Sobald es draußen kälter wurde kühlte die Klima auch wieder herunter. Sie lief unter extremen Bedingungen 39° Außentemperatur das darf man nicht vergessen

Excellent produit et d’une grande efficacité. Séjour 35m2. Malgré la canicule des derniers jours, 39 sur le balcon plein sud séjour à 25 degrés constant. Autant faut il poser le calfeutrage fourni avec.

Le climatiseur fonctionne bien il n est pas plus bruyant qu un autre climatiseur mobile, il refroidit bien , le seul point negatif que je trouve est que je n ais pas reussi a le regler en wifi.
