Verdict

The Supra DUBTI2 is a desiccant rotor (compressor-free) dehumidifier designed for a coverage area of up to 30 m², featuring an extraction capacity of 8 liters per day, a 2-liter transparent water tank, and a maximum power consumption of 650 W. It offers distinct advantages including an ultra-low operating temperature range of 1°C to 40°C making it ideal for unheated spaces like basements, alongside a built-in independent ionizer, an antibacterial air filter, a 1-to-8-hour programmable timer, and support for continuous drainage. However, it suffers from a relatively high power consumption of 650 W for its low daily output, a small 2-liter tank capacity requiring frequent emptying if not connected to a drain hose, and a peak noise level of 48 dB which can be noticeable in quiet environments.
