Is the EcoAir DD1 Simple MK3 worth it?
Yes — for cold spaces.
As a desiccant model it keeps working in cold rooms where compressor models struggle, so it suits garages, sheds, conservatories, caravans and outdoor offices. It weighs about 6 kg, is controlled with a single dial and has a laundry mode and a turbo setting. The 2 L tank needs emptying often, though a 1 m drain hose is included, there's no timer, and it costs more to run all day than a compressor model.
