Understanding dehumidifiers
What is a dehumidifier?
A dehumidifier extracts excess moisture from indoor air, preventing condensation and damp issues. This promotes better indoor air quality, prevents mould and mildew growth, and protects your belongings.
Why should you buy a dehumidifier?
Health benefits of a dehumidifier
- Purify air, reducing dampness, mould, and musty odours.
- Ease allergies by eliminating dust mites and pollen.
- Help asthma patients by regulating moisture for easier breathing.
How does a dehumidifier work?
Dehumidifiers operate by pulling room air through cold coils. As warm, humid air encounters these coils, it condenses into water droplets that collect in a tank. The air is then reheated before re-entering the room.

Dehumidifier features
Here are some features to consider when choosing a dehumidifier for your home.
Litre capacity
A dehumidifier's capacity is measured by the amount of moisture it removes in a day. Choose a model with a higher litre capacity if your space is prone to dampness and ensure effective moisture control.
Noise level
Some models of dehumidifier are louder than others. So, if you're planning on running a dehumidifier in a quiet environment such as a bedroom or nursery, look for one with a noise level under 45 decibels.
Laundry drying
A dehumidifier with a laundry mode efficiently removes moisture from your clothes so that they dry more quickly. This is especially useful in the winter months when it’s often too cold to hang clothes outside.
Low temperature operation
Dehumidifiers operating in cold spaces like basements or garages need frost control to prevent ice buildup. Without it, performance may suffer, or the unit might shut down entirely due to the accumulated ice.
Choosing the best dehumidifier for your home
What size dehumidifier do I need?
To determine the ideal dehumidifier size, assess the size and moisture level of your space. Generally, spaces with moderate humidity need a unit extracting 10 to 20 liters daily. For smaller areas like laundry rooms or closets, opt for a lower capacity model.
How much does a dehumidifier cost to run?
The cost to run a dehumidifier varies depending on its energy rating, size and usage. Some models are more energy efficient than others, providing the same amount of dehumidification while using less electricity.
Are dehumidifiers energy efficient?
Energy-saving benefits of a dehumidifier
From helping to reduce central heating usage to drying clothes, a dehumidifier can have several energy-saving benefits. Most new models also have an auto shut-off feature for optimised energy usage. Pick the right size and maintain it regularly for increased energy efficiency and lower bills.
