Avalla S-290 Review | 44 Data compared

The Avalla S-290 is a versatile 3-in-1 portable air conditioner that combines a 10,000 BTU maximum cooling capacity, a 2-speed fan with a 310 m³/h airflow rate, and a powerful 24L/day dehumidifier. It features an Energy Class A efficiency rating using eco-friendly R-290 refrigerant, an auto-sensing temperature mode capable of cooling down to 16°C, a 24-hour timer, a child lock, a washable filter, and easy mobility via built-in casters. Major pros include its ability to cover large multi-room spaces up to 100 m³, an inclusion of a specialized sash window installation kit, and relatively quiet real-world operations reaching down to 54dB. On the downside, the unit weighs a heavy 23.13 kg, can feel somewhat loud on its highest settings according to some user feedback, and its required exhaust hose installation can initially feel slightly gimmicky or tricky to secure.
