If you are looking for a really small, quiet and efficent dehumidifier then the DD1 Simple could be your best choice. Size wise it is about as small as you can get. Being a desiccant machine means it generates a little bit of heat when it runs and the exptraction performance does not vary with temperature. This makes it really good the drying laundry and equally as good in unheated environments such as garages, workshops and stores (where we can supply a suitbale hose so you can put it on continuous drainage).

We like the simple rotary knob control - no gimmicks or gizmos to confuse. You can set the machine to two humidity levels or run it continuously. It has two fan speeds so you can really blast out the dry air if you want to get drying done quickly.

Best of all it comes with our exclusive THREE YEAR WARRANTY as standard. Any issues in the first three years and we collect it from you, repair it and return it completely free of charge.

This has proved to be an excellent machine coping with all weather conditions extremely well. However, a slight niggle has arisen when I connected the permanent drain tube. All was fitted according to the instructions, machine level and with a clear gravity drain run. But the reservoir still needs emptying every few days and close inspection showed that the unit over the reservoir appears to have a foam sealing ring which was soaked and allowing water to drip into the reservoir below. So, back to reservoir use where it has performed flawlessly.

100% product and service. Delivered next day. We had problems with drying out a newly plastered garden room ready for painting. The dehumidifier reduced the water content within a day from 99% to 50% (and this was with no other heating in the room. ) Highly recommended.

Has been in continuous use for some months now in my fibreglass observatory and has been flawless in warm, cold and freezing conditions keeping equipment dry and also providing some background heat. Excellent advice from DiO led to this purchase over a more expensive model. Thank you.
