It's simple to use. No frills. All you do is turn its dial around clockwise and a jet stream of odourless steam puffs up and out, humidifying the air you breathe, so your nose doesn't get dry or your throat scratchy.
Sleeping with this humidifier at night is like sleeping in a bedroom-flavoured rainforest. Mine is orange, but the experience is no doubt just as lovely with any of its other candy-coloured models. [Amazon]
