The levels of relative humidity in the air can affect your comfort and even affects how your ac units function. In the UAE, indoor relative humidity is one of the biggest problems residents face. This is why keeping a safe indoor humidity level using dehumidifiers is important.
But what is Indoor Relative Humidity?
The capacity of the air to hold water changes as the temperature changes. Indoor Relative humidity is the amount of water vapor present in air indoors. This is usually shown as a percentage of the amount needed for saturation at the same temperature. It is ideal to keep indoor humidity below 60 percent and keep a 30-60 relative humidity.
How does a dehumidifier work?
Dehumidifiers remove excess moisture from the air, thus, regulating the humidity in the room. Having dehumidifiers in a room helps avoid dust mites, molds, and allergens. This is an effective way to curb allergic reactions especially in the UAE where a lot of people are suffering from asthma and allergic rhinitis.
Basically, dehumidifiers take moisture in a gas form from the air and remove it as liquid water. Dehumidifiers remove excess moisture from the air.
There are 4 different types of dehumidifiers:
- 1.Heat Pump Dehumidifier- Consists of a fan, heat pump, and heat exchange coils.
- Dehumidifying Ventilator- Uses an exhaust fan to expel air outside and a sensor.
- Chemical Absorbent or Desiccant Dehumidifier- Has hydrophilic materials like silica gel.
- Homemade Dehumidifier –Which are made from charcoal or a special kind of salt.
However, there are only two methods by which dehumidifiers work.
Refrigeration dehumidifiers are standard types of dehumidifier because they are simple to use and effective in removing excess moisture in the air.
Meanwhile, Desiccant or Absorption dehumidifiers use a different method of dehumidification which gets rid of excess moisture by squeezing or mopping it out of the air,
Indoor air dehumidifiers are just like air conditioning units. A fan draws moist air inside the dehumidifier, then this air condenses on the coils.
Here’s a simple illustration explaining the process of dehumidification.

Dehumidifiers have a drip pan or a bucket for collecting and easy disposal of condensate, as well as a pump for drainage. The cooled air which passed by the refrigerant) slightly heats the air before it is released back into the room. This air attracts moisture and regulates the indoor relative humidity level.
