Which? Best Buy Award Winner with Industry-Leading Extraction

The DD3 Classic MK3 has been awarded Which? Best Buy product of the year. With an 11 litre per day extraction capability, it is currently the largest extraction rate domestic desiccant dehumidifier on the market today. It is ideal for homes of 3 to 6 bedrooms up to 90m².

Winter Performance and Energy Efficiency

This dehumidifier is ideal for winter use because it releases slightly warm air, which helps to warm up the space and dry your clothing. As the air becomes drier, your heater can function more efficiently, potentially saving energy.

Digital Display and E7 Technology

The MK3 version features a digital display showing your ambient humidity level and your set humidity when you press the humidity setting button. It utilises air sampling and automatic toggling with E7 Technology for efficient dehumidification.

Enhanced E7S Energy-Saving Technology

The unit automatically stops when ambient humidity reaches your desired setting and automatically turns on when humidity rises above it. In auto mode, the dehumidifier will automatically switch to full power if it detects humidity levels over 10%. If humidity is above the setting but below 5%, it switches to economy mode.

If your humidity setting exceeds the current room humidity, the humidity setting LED will blink and the machine switches to energy-saving mode. The heater turns off and the fan stops running two minutes after cooling down the internal parts. After 30 minutes, the fan starts and runs for 5 minutes while the unit samples the air. If humidity is higher than 5% of the set value, dehumidification begins. If not, the unit pauses for another 30 minutes.

Electronic Control Panel

The easy-to-use digital control panel offers 5 pre-programmed humidity settings from 40 to 60% RH at 5% RH intervals.

Antibacterial Silver Filter

The antibacterial filter kills air-borne bacteria on contact. Clean the filter using a soft brush or gentle vacuum every 2 weeks to maintain clean air and dehumidifier longevity. Replace the filter at least once every 6 months for optimal performance, as hygiene standards and antibacterial properties diminish over time.

Laundry Mode

A powerful laundry function helps you dry laundry indoors. When activated, the DD3 MK3 runs on full power continuously until you change your settings.

Water Tank with Large Capacity

The DD3 Classic MK3 has a large 4.2 litre tank with a lid to avoid spillage and a carry handle for easy transport to the sink for emptying. An optional continuous hose is also available.

Auto Restart Function

The DD3 Classic MK3 automatically restarts after a power failure. Once power is restored, the dehumidifier continues to operate at your selected settings.

Anti-Tilt Safety Protection

The DD3 Classic MK3 is equipped with tilt-over safety protection that powers off the unit automatically if it tilts over, safeguarding you and preventing hazards.
