Dehumidifiers are used to remove trace amounts of water in the air. Humid air can cause mould or mildew to grow, posing numerous health risks. After using a caravan in damp or wet conditions, it is good practice to use a dehumidifier to lower the moisture in the air and prevent condensation and any issues it may cause.
Dehumidifiers come in a range of types and designs. The most common type is a Moisture Trap; these are filled with crystals that extract the water from the air and deposit it in a lower tray. Some of these types are refillable by simply replacing the crystals after a particular time.
Some Dehumidifiers are electrical and draw moisture from the air via extremely low powered heating elements. These types have indicators showing when they need emptying or recharging and can be sustained for 3 to 4 months before charging.
Drybag dehumidifiers are designed to absorb dampness directly from the air. Rather than dropping it into a tray or container, the material in the drybag holds onto the water and can be disposed of safely after a few months. Drybag types change colour, and once darkened off, you know it's time to replace them.
