Verdict

The Klarstein Metrobreeze New York Smart is a 3-in-1 portable air conditioner, fan, and dehumidifier available in variants ranging from 7,000 BTU (2.1 kW) up to 12,000 BTU (3.5 kW) of cooling power, supporting an adjustable temperature range of 17–30 °C and an airflow max of 290 to 360 m³/h. It features an Energy Efficiency Class A rating, an eco-friendly R290 refrigerant, a 24-hour programmable timer, 3 fan speeds, and built-in floor castors for easy mobility. Its main pros include highly flexible smart operation via Wi-Fi with the Klarstein app, Amazon Alexa, or Google Home, alongside included window sealing kits that eliminate the need for fixed installation. However, notable cons include an operating noise level that can reach up to 65 dB at maximum settings, a relatively heavy weight of around 28 kg, and the mandatory requirement of an external exhaust hose.
