The Mijia Air Conditioner GentleAir 3.5 kW is a mid-range wall-mounted split unit from Mijia, Xiaomi’s smart home brand. It is a 12,000 BTU inverter model that cools and heats, sold as an indoor and outdoor pair. The white indoor unit is 295 x 795 x 205 mm, and Xiaomi rates it for rooms of 15 to 25 m². The 3.5 kW is one of four GentleAir sizes, alongside 2.6, 5.2 and 7.0 kW. All four share a new flap with up to 602 micro-holes, which splits the airflow into thinner streams and slows the wind. There are three airflow modes. Xiaomi claims 30-second cooling and 60-second heating.
Cooling and heating capacity are both 3,700 W, from a full DC inverter. It draws 1,423 W when cooling and 916 W when heating, and it is rated A++ for cooling and A+ for heating. Xiaomi says AI mode lowers energy use by up to 24.5%, without saying compared with what, so treat that figure with caution. It also has a sleep mode that adjusts temperature, airflow and noise, auto restart after a power cut, and a self-cleaning cycle. It works with the Xiaomi Home app and Google Assistant.
In Spain it sells for about €620, with installation about €300 extra. The 2.6 kW costs about €570 and the 5.2 kW about €960. At 15 to 25 m², it fits a bedroom or a small living room where you want both cooling and heating. Inside the Mijia range it overlaps with the Eco 3.5 kW and the Pro Eco 3.5 kW, which launched in Europe at €699. Outside it, the Samsung WindFree Avant 3.5 kW and the Midea Xtreme Save 3.5 kW compete in the same size class. The Pro Eco 3.5 kW is the best head-to-head match: same capacity, same room size, about €79 more.
