Desiccant works better in the winter and quiter. The downside is they are costly to run, around 600w. And they generally leave bad smell in the air.
Ordered one. They are delivering it tomorrow. Topcashback tracked for me, but only £2.37.
Heat added. Only 4% Quidco for Electricals sales, however Topcashback gives 5.05%.
As noisy as a fan heater.
