They say when it rains, it pours, and unfortunately wet and humid weather can cause mould to turn up in your bathroom, wardrobe and other parts of your home at any time of the year. While there are plenty of DIY mould removal and prevention strategies, a dehumidifier can be one of the best ways to effectively combat damp or muggy weather in Australia.
As someone who lives in a sub-tropical part of the country, I can tell you first-hand that I’ve used a lot of strategies (including DIY dehumidifiers) to deal with mould. But buying an actual dehumidifier was a game-changer, keeping the bathroom mould-free for months at a time, preventing musty smells in the wardrobes and even helping dry clothes during wet weather (thanks to the laundry mode).

How does a dehumidifier work?
Differing from portable air conditioners and evaporative coolers that work to cool a room, often with moisture, dehumidifiers work by sucking air through sensors to extract moisture from the air. This moisture then goes into a water storage container you empty when full.
“Due to their portable nature, dehumidifiers are great to use in various parts of your home that may have issues with moisture or mould,” Appliances Online category expert Colin Jones says.
“These units are best placed in rooms that have a lack of ventilation or excess moisture,” Colin says, “On high humidity days, you may want to consider using these between 10 to 12 hours a day, even 24/7 if your unit has the capacity”.
“Most dehumidifiers use little power, which will allow you to operate these for long periods of time. Having a unit such as a portable dehumidifier will help in protecting parts of your home and clothing.”
Colin recommends the following sizes:
- 6-10L capacity dehumidifier for cupboards or wardrobes
- 10-25L capacity dehumidifier for small areas
- 20-35L capacity dehumidifier for medium areas
- 35L+ capacity dehumidifier for large areas
How can I tell if humidity is damaging my home?
Colin highlights there are several signs that high humidity levels are having an impact on your home and belongings, these being:
- Water stains on your walls or windows
- A musty smell from a specific area
- Small amounts of mould beginning to appear
- Windows beginning to look foggy and small amounts of running water
- Your skin feels tight, clammy and sticky
The rising popularity in dehumidifiers in Australia suggests most of us have some issues at home, made even more extreme by seasonal patterns and increased rain events. In fact, the dehumidifier market is now expected to grow 7.2% per year to a value of US$36.4 million by 2030 according to market analysis by Grand View Research.
