Verdict

The Aktobis WDH-520EB is an energy-efficient digital compressor dehumidifier designed for rooms up to 50 m², featuring a maximum moisture extraction capacity of 25 liters per day (at 35°C / 90% r.h.) and a standard capacity of 20 liters per day (at 30°C / 80% r.h.). It is equipped with a 5-liter condensation tank, a built-in LED electronic hygrostat adjustable in 5% increments (30% to 90%), a 1–24 hour timer, two fan speed levels, and an automatic overflow protection shut-off. Main pros include its eco-friendly design with a low average power consumption of 330 W (505 W maximum), smart home capability via an external WLAN socket, a continuous drainage option via a hose connection, and mobile flexibility aided by a carry handle and wheels. On the downside, it only features a basic washable dust filter rather than a multi-stage HEPA air purification system, and its operation at 46 to 51 dB means it may feel a bit noisy for light sleepers when used directly inside a bedroom.
