How does a dehumidifier work?

  • A fan collects air from the surrounding space and pulls it into the dehumidifier.
  • As the air passes through, it comes into contact with the dehumidifier’s cooled coils. These coils use condensation to pull moisture from the air. The collected moisture remains on the coils and drips into the dehumidifier’s bucket.
  • The bucket is easily removable and simply clips back in once emptied.
  • The dehumidifier then reheats the air and exhausts dry air back into the room.
  • Our dehumidifiers come with filters which extract the allergens from the air before releasing it back into the room, resulting in a far healthier environment.

What is the difference between a desiccant and a refrigerative dehumidifier?

With the refrigeration type dehumidifier a compressor is used to pump refrigerant through a closed piping circuit, much like an air conditioner. Humid air passes over the cold surface causing moisture in the air to condense into water droplets and collect in the bucket. These units are best suited to environments where your humidity is worse in warmer climates.

The desiccant units collect moisture from the air by passing over a heated rotating wheel which contains drying material. It extracts the moisture from the air and dry air is released is hence slightly warmer, which is why these units are best suited to areas where your humidity occurs in colder climates.

How often does the bucket need to be emptied?

This depends on how much humidity is in your home. The dehumidifier will automatically turn off when the bucket is full. All our dehumidifiers offer a continuous drainage option, which means you can connect a section of hose and lead it into a drain and the dehumidifier will then operate continuously until the desired humidity is reached.

How do I know what the humidity level is in the room?

Most of our units have LED displays which can tell you the current humidity range in an area. You can select humidity levels from 40% upwards and once the room in which the dehumidifier is in reaches that level, it will turn off. The humidistat in the unit will pick up when moisture levels increase and the unit will switch back on again. This is true in our manually operated models as well.

How much electricity does it use?

All our units are incredibly economical with A+ energy ratings. Desiccant units tend to use more power than refrigerant units, but because they don’t need to operate for as long, the energy consumption is still quite low.
