A Mini Guide To Dehumidifiers And Their Uses

Dehumidifiers are electronic appliances that draw in warm and humid air, cool it to remove moisture content and then release it back into the environment. They are used to condition air making it cooler and removing excess moisture.

Types Of Dehumidifiers

Dehumidifiers can be classified according to how they work and their size. With regard to classification according to size, you have mini, medium size and whole house dehumidifiers. Mini dehumidifiers are small appliances weighing a few kilograms and are designed for use in small spaces. These are the types of dehumidifiers we cover in our reviews. Medium size dehumidifiers are larger than the minis. They’re designed for use in slightly larger rooms. Some of these also act as air purifiers and feature air filtration systems. Whole house dehumidifiers are large units which are usually installed outside the house. They’re connected to networks of ventilation systems which branch out to the different rooms in the house. They usually work by blowing in cool air into the rooms and drawing out warm humid air.

Now let’s have a look at the classification by how the dehumidifier works.

Refrigerant Dehumidifiers

These have a fan which draws warm humid air into the dehumidifier. A refrigeration method such as a compressor or thermo-electric cooling cools a metal plate upon which the warm air is driven. The cooling metal plate draws moisture from the air which is then released into the environment.

Desiccant Dehumidifiers

These dehumidifiers use a chemical such as silica gel attached to a rotating wheel. As humid air passes through the desiccant, moisture is drawn from it. As the wheel continues to rotate, the moisture within the desiccant is drawn and drained out of the unit by passing the desiccant through warm air. These types of dehumidifiers are usually smaller compared to refrigerant types and usually make the best quiet dehumidifier.

Ventilation Dehumidifiers

These make the best home dehumidifiers, they are quiet and inexpensive to operate. They usually operate by heat exchange where cool fresh air is drawn into the house, displacing warm humid air.

What To Consider Buying A Mini Dehumidifier

Mini dehumidifiers are designed for use in single spaces such as the bathroom or a car. They’re highly portable and easy to operate. If you’re looking for the best compact dehumidifier, here are some considerations to make.


With regard to mini dehumidifiers, size might mean two things. First, it means the dimensions of the unit. If you’re limited on space, a smaller dehumidifier is recommended. The second meaning of size is its volume capacity. That is, how much water the collection tank will hold before it needs to be emptied.

Daily moisture removal rate

The better economical dehumidifiers will usually remove between 200ml and 500ml of moisture from the air every 24 hours. The amount of moisture removed will however, depend on relative humidity and prevailing temperatures.

Noise output

Mini dehumidifiers are usually designed for rooms such as the bathroom, bedroom or even office. You’ll want a unit with quiet operation.

Power consumption

Mini dehumidifiers usually operate on a 12 or 9 volt power source. This however isn’t really important. The rating you should really be looking at is the wattage rating. A higher wattage rating means you’ll end up paying higher electricity bills.
