Verdict

The Klarstein Metrobreeze 9 New York City is a portable 3-in-1 air conditioner, fan, and dehumidifier that delivers a cooling capacity of 9,000 BTU (2.6 kW) with a power consumption of 1,050 W and an Class A energy efficiency rating. Designed for rooms ranging from 23 to 33 m², it features an adjustable temperature spectrum of 16–30 °C, a 3-speed fan, a 24-hour programmable timer, an integrated LED control panel, and a standalone dehumidification mode. Its primary advantages include excellent cooling performance, 360° caster wheels for flexible multi-room mobility, and the inclusion of a full window sealing kit with a 1.5-meter exhaust hose; however, it suffers from a high maximum noise level of 65 dB, making it quite loud for light sleepers, and a bulky 26 kg frame.
