Dehumidifier for bedroom mould: what it will and will not do
A bedroom dehumidifier is worth buying if the room stays damp. Treat the mould you can see first. First Light is the treatment for the stain. The Protection Kit is the set-up for a shut, humid bedroom.
A dehumidifier takes water out of the air. It does not remove mould already on the wall, the bedding, or the wardrobe. For the science of that split, read do dehumidifiers stop mould.
How to size one for a bedroom
Buy for the size of the room you will actually run it in, a tank you will empty (or a hose you can drain), and a noise level you can sleep near. Compressor units are common in warmer rooms. Desiccant units can be the better fit in a cooler bedroom. We have not lab-tested a ranked list of brands, so this page will not invent one.
Where to put it, and what to do with the wardrobe
Stand it where air can move around it, not behind a door or under hanging clothes. If the wardrobe is the wet corner, keep that door open while the machine runs, and treat the cabinet itself. Wardrobe method lives on mould in the wardrobe and on clothes. For why the bedroom goes mouldy, use why is my bedroom so mouldy.

Dehumidifier vs a waterless diffuser
They do different jobs. A dehumidifier removes moisture. A waterless diffuser runs oils in the room without adding water to the air. If you are buying a diffuser for a damp room, use best essential oil diffuser for damp rooms. For humidity in the house more broadly, see how to reduce humidity.
