What’s the Difference Between Desiccant and Compressor Dehumidifiers?
Before getting into the extras, it helps to understand what makes desiccant models different. These don’t rely on refrigerant coils or a compressor. Instead, they use a moisture-absorbing material, usually silica gel, to draw in damp air. This makes them quieter, lighter, and often more effective in cooler environments like garages, basements, and older homes with poor insulation.
If you’ve got a chilly flat, a north-facing bedroom, or a damp wardrobe, a desiccant unit is a solid choice. Compressor models can struggle a bit when it’s cold, while desiccant types keep working regardless of the temperature.
Are desiccant dehumidifiers safe to leave running?
Yes, the small ones are perfectly safe to leave running, even in a cupboard or wardrobe. They don’t give off heat or use any fans, so there’s no fire risk. If it’s a rechargeable type, just follow the instructions and don’t overcharge it. Most have automatic shut-off anyway, so they won’t overheat.
Can I use more than one in the same space?
Absolutely. If you’ve got a bigger area or several small damp spots, using a couple of units is a good way to stay on top of it. Just make sure they’re spaced out and not sitting right next to each other.
Do they get rid of smells too?
To an extent, yes. A lot of musty smells come from damp and mould. Once the moisture is under control, those smells usually go away. But if something’s already gone mouldy, you’ll still need to give it a proper clean.
Will it work in a freezing garage?
Yes, that’s one of the big advantages. Unlike compressor models that don’t work well in the cold, desiccant dehumidifiers keep absorbing moisture even when it’s near freezing. They’re a popular pick for sheds, garages, and caravans stored over winter.
