What is a good non electric dehumidifier for a caravan or shed?

[IronFist66]

I want something simple for storage spaces where I do not want to run power. What would you use?

[Totally]

For a caravan, shed or cupboard, I would use UniBond AERO 360 Moisture Absorber because it does not need power and is easy to empty

[Di87]

You will need refills, so I would also keep UniBond AERO 360 Moisture Absorber Neutral Refill Tab around if the space is damp

[HiggsField29]

It will not dry a whole building, but it can reduce musty smells in smaller enclosed spaces

[RomanReigns02]

I would still ventilate the area whenever possible, because moisture absorbers are not magic
