A spin dryer is an appliance that can readily improve the energy efficiency in your laundry. A portable spin dryer like this one from Laundry Alternative, uses centrifugal force to dry clothes. The dryer was out of stock for a while, but it is now available again. Spin drying is much more efficient than electric tumble drying, in terms of energy use. Spin drying is also faster — it takes 2-3 minutes to get clothes to a semi-dry state. The drying can then be finished by hang drying the clothes or putting them in a tumble dryer for a few minutes. Spin drying is much gentler on clothes than tumble drying, it also removes mineral deposits and detergents, rather than baking them on. The spin dryer costs $129.95, which is much less than the previous spin dryer we featured, the Spin-X.
Update: I’ve been testing this spin dryer for a few months now, and it works quite well. It does make a bit of noise as it spins, but the noise is reduced if you load the dryer evenly. You have to get used to loading the dryer 2-3 times to dry a whole wash load. But many of my clothes come out of the machine practically dry - they are just a little damp to the touch.
