Immensely popular, the DD1 Classic MK5 (formerly DD122 CLASSIC ) is an ideal solution for flats, small homes, boats and caravans. Boasting E7 Technology and 3D Louver, this unit pushes the boundaries when it comes to performance. So what is E7 Technology? As an effective way of reducing energy consumption, it\'s second to none. Sensing both the temperature and humidity levels, it allows the unit to switch between full power, economy power and has been shown, when compared to dehumidifiers without the technology, to reduce electricity bills by as much as 40%. The 3D Louver is a design function that targets airflow to where it is most needed, making for a far more efficient process, and ensuring the operation is concentrated on specific problem areas. But that\'s not all the  DD1 Classic MK5 (formerly DD122 CLASSIC ) has to offer. If you are using the unit on its highest setting (or in laundry mode), it will automatically adjust the process to prevent the ambient air becoming too dry. All of this adds up to a desiccant dehumidifier that \'s capable of reducing humidity, damp and mould, resulting in an all round healthier home.   Key Facts:   Perfect for: Flats/Appartments, caravans, garages and boats   Product Size: W290mm x D175mm x H475mm   Tank size: 2 Litres Extraction rate: 7 Litres(24/h)   Humidistat: Yes Noise: 34 dB(A) Filter: Yes Efficiency: 360-620W   Our technical editor says:   “An ever-popular model that combines economical performance with outstanding technologically advanced features, such as the 3D louvre.  Two year guarantee is a bonus”
