  • One compact unit, three ways to improve your air: Air conditioner, fan, and dehumidifier are all built into a single compact unit — so you can tackle any climate challenge without cluttering your space with extra devices.

  • Quiet enough for the bedroom: At its lowest setting, the unit runs at just 52 dB — below the level of a normal conversation — so it won't disturb your sleep or your concentration.

  • No drilling, no fuss — up and running in minutes: The telescopic exhaust hose and window seal mean you can have the Metrobreeze New York Smart 12k installed and cooling in no time, with no permanent changes to your room and no need for a tradesperson.

  • Control it from anywhere: Full Amazon Alexa and Google Home integration means you can adjust the temperature, change modes, or set a timer by voice or via the Klarstein app — whether you're on the sofa or on your way home.

Product description

When summer turns your living room into a sauna and your home office into a greenhouse, the Klarstein Metrobreeze New York Smart 12k is ready. With 12,000 BTU / 3.5 kW of cooling power, it brings rooms up to 56 m² back to a temperature you can actually live in — no installation, no drilling, no fuss.

Whether it's a spacious open-plan lounge, a double bedroom, or a dedicated home office, the Metrobreeze New York Smart 12k handles rooms of 42–56 m² with ease. You choose your preferred temperature anywhere between 17 and 30 °C, and it gets on with the job quietly — at its lowest setting, it runs at just 52 dB, which is quieter than a normal conversation. Energy efficiency class A keeps running costs in check too.

This isn't just an air conditioner — it's a portable air con, fan, and dehumidifier combined in one unit. Switch between all three modes from wherever you are: via the Klarstein app over Wi-Fi, the included remote control, or directly on the unit itself. Amazon Alexa and Google Home are fully integrated, so you can adjust the temperature or set a timer with nothing more than your voice. The 24-hour programmable timer means you can set it up before you leave and arrive home to a cool, comfortable room waiting for you. The telescopic exhaust hose and window seal get you up and running quickly, without any permanent changes to the room. The R290 refrigerant (245 g) has a low global warming potential.

Perfect for renters, home workers, or anyone who needs serious cooling flexibility — across a living room, bedroom, home office, holiday let, or studio. The Metrobreeze New York Smart 12k goes where you need it, cools what you need cooled, and lets you stay in control from anywhere.

Stay cool this summer — order the Metrobreeze New York Smart 12k and enjoy a comfortable home on your terms.

The build quality is excellent, and I love that it connects to a mobile phone. I did encounter one issue with the app: when I try to change the mode through my phone, it doesn’t actually switch. However, that’s not a big deal for me. The cooler came with a set of accessories that allow you to secure an open window, which is a great feature. The only downside was the shipping, it took about 10 days for the package

Que le climatiseur fonctionne très bien.fait un peu de bruit,mais cela reste correct.

The air conditioner works very well. It makes a little noise, but it's still okay.

Verified review 16/07/2025

A funcționat bine in primul an. Când să îl pun la treabă în iulie 2025, am observat că s-a transformat într-un simplu ventilator. Nu mai baga aer rece. Surpriza mare a fist că trebuie să îl împacheteaz și să îl trimit înapoi pentru garanție. Nu au posibilitatea să rezolvi local cu garanția. O mare problema.

It worked fine for the first year. When I put it to work in July 2025, I noticed that it turned into a simple fan. It no longer blew cold air. The big surprise was that I had to pack it up and send it back for warranty. They don't have the option to fix it locally under warranty. A big problem.

Macht was er soll, kühlen und das sehr gut.

Does what it's supposed to, cool, and does it very well.

Verified review 01/07/2025

Super Klimaanlage kühlt den Raum auch wirklich runter und ist halt leider auch nicht die leiseste aber sie muss ja auch kühlen und der Kompressor kann nun mal nicht leise sein! Kann die schlechten Empfehlung der Klimaanlage überhaupt nicht nachvollziehen! Auch funktioniert die App absolut tadellos! Absolute Kaufempfehlung

Great air conditioning, really cools the room down, and unfortunately, it's not the quietest, but it has to cool, and the compressor can't be quiet! I can't understand the poor recommendation for this air conditioner at all! The app also works perfectly! Absolutely recommend it!
