1. Moisture & Odour Removal

2. Ultra Quiet Operation

Built-in Thermo Electric Cooling Technology (Peltier) operates without a compressor, resulting in noise levels below 30 dB. This makes the unit suitable for use in bedrooms, studies, or other quiet environments.

3. Energy Saving & High Efficiency

Power consumption is only 23 W/hour (0.552 kWh over 24 hours). The 500 ml (17 oz) water tank collects up to 300 ml (9 oz) of water per day under standard conditions (25°C, 85% RH).

4. Auto Shut Off & LED Indicator

A built-in water level monitor automatically shuts off the dehumidifier when the water tank is full. A red LED indicator lights up to alert the user. After emptying the tank, simply place it back into the unit to resume operation.
