Using a dehumidifier well in a damp Marbella winter
Where to place a dehumidifier, which type suits a cool Costa del Sol home, and how to keep it clean so it removes damp instead of spreading smells.

Measure first, then decide
Winter on the coast is mild, but the air can stay heavy for days, especially in homes that are closed up or only heated now and then. Condensation on windows, a musty smell in wardrobes and dark spots in corners are the usual signs.
A small hygrometer, the kind that shows humidity as a percentage, costs very little and removes the guesswork. Most people feel comfortable and keep mould at bay when indoor humidity stays roughly between 40 and 60 percent. Check it in the bedroom and the bathroom at different times of day before buying anything.
Choosing the right type
Compressor models are the most common and work well in a warm, damp room. In a cool, unheated villa or a ground-floor storage room they become less effective, because they collect less water as the temperature drops.
Desiccant models use a drying material instead and cope better with cold. They tend to warm the room slightly, which is a bonus in winter. Whichever you choose, look for a built-in humidity setting, an automatic shut-off when the tank is full and a washable filter.
Where to put it and how to run it
Place it in the room where the problem is, a little away from walls and furniture so air can move around it. Keep doors and windows of that room closed while it runs, otherwise it is trying to dry the whole street.
Set it to around 50 percent rather than the maximum. Running it constantly at full power wastes electricity and can dry out wooden furniture and floors. Air the room briefly each morning, then close up and let the machine do its job.
Keeping the machine clean
A dehumidifier collects water, and standing water breeds bacteria and unpleasant smells. Empty the tank daily, rinse it and let it dry. Once a week, wash the air filter in lukewarm water with a little mild soap and dry it fully before putting it back.
Every month or so, wipe the tank and the outside with a cloth dampened with diluted white vinegar, and check the coils or grille for dust. Always unplug the machine first. If you leave it for a long period, empty it completely and store it dry.
It helps, but it does not fix the cause
A dehumidifier lowers humidity; it does not remove mould that has already grown or repair a leak. If you see recurring black patches, a damp wall or a persistent smell, the source needs finding. Wipe visible mould from hard surfaces and ventilate, and seek a professional opinion for anything structural.
If you are away for part of the winter, a regular visit helps. Lavanda can air your home, wipe down damp-prone areas, empty and check appliances and tell you what we notice, so you return to a fresh house.
