Third-party reviews

Based on ratings from across the web.
Reviews last updated: August 2026 · How we calculate this

What we like about Klarstein Metrobreeze Rom

  • Highly effective at cooling small to medium rooms quickly
  • Excellent energy efficiency with an A+ rating that keeps electricity bills in check
  • Versatile 3-in-1 functionality operating as an air conditioner, dehumidifier, and fan
  • Smooth ground rollers and transport handles make it easy to move between rooms
  • Convenient control options via the top control panel, remote control, and Klarstein smart app integration
  • Comes with included accessories such as an exhaust hose and window sealing kits

What we don't like about Klarstein Metrobreeze Rom

  • Operational noise can be quite loud and disruptive, especially for light sleepers during nighttime use
  • The unit has a relatively large, bulky, and heavy physical footprint
  • Draining the water tank can be awkward and inconvenient due to the position of the drain plug
  • Occasional software connectivity issues with the mobile app failing to switch modes smoothly

Verdict

The Klarstein Metrobreeze Rom is a 3-in-1 portable air conditioner featuring cooling, dehumidifying, and three-speed fan modes with a 10,000 BTU (3.0 kW) capacity, structured for rooms between 28–42 m². It operates within an adjustable temperature range of 18–30 °C, utilizes eco-friendly R290 refrigerant, features a 24-hour programmable timer, and includes an A+ energy efficiency rating alongside built-in floor rollers and an included window seal kit. Its main advantages include powerful, cost-effective cooling, smart Wi-Fi app integration with voice control options, and an easy, non-permanent DIY installation. However, some users note downsides, including its bulky physical profile and a maximum operating noise level reaching up to 64 dB, which can feel loud for light sleepers.
