Dehumidifiers

Maintain control over the humidity levels in your home with a dehumidifier from Appliances Online. Dehumidification refers to the process of removing excess moisture from the air to help prevent mould, mildew, dust mites, and allergens from becoming prevalent in the home.

Improve your home air quality with a selection of dehumidifiers from big brands including Delonghi, Ionmax, Breville, and Dimplex.

Select the type of dehumidifier which will be ideal for your needs, as well as suiting the climate of the area. Compressor dehumidifiers/refrigerant dehumidifiers draw air in, cool it to condense water into a water tank, reheat it, then expel the warmer air back into the room. This makes them ideal for warmer areas.

Desiccant dehumidifiers use a desiccant wheel to absorb moisture from the humid air, while an internal heater heats the damp sections to condense the water into a tank. Since they don't utilise a compressor, desiccant dehumidifiers often have a lower noise level when compared to other models.

Some units, such as the Breville All Climate Dehumidifier, are suitable for use all year round. Not only removing humidity, this dehumidifier also utilises a two-stage air filter to remove allergens from the air.

For a powerful and compact dehumidifier, look no further than the Ausclimate Cool Seasons, capable of removing ten litres of water per day.

A desiccant dehumidifier is a type of dehumidifier that uses a moisture-absorbing material (called a desiccant) instead of a compressor to extract water from the air. Inside the unit, a rotating desiccant wheel soaks up humidity from incoming air, and an internal heater then dries the wheel, collecting the released water into a tank. Desiccant dehumidifiers perform especially well in cold temperatures - if your space is unheated or regularly falls below ~20 °C, a desiccant unit will continue to remove moisture effectively when compressor models might struggle. They also tend to be lighter and quieter than compressor models (since there’s no motor noise from a compressor). In Australia, desiccant dehumidifiers are a popular choice for winter use or in chilly areas like garages and basements, with compact models (like Ausclimate’s Cool Seasons range) offering powerful drying capacity even in cool climates.

The best dehumidifier for mould problems is one that can consistently keep your room’s humidity below about 50% relative humidity. Mould thrives in damp air, so any quality dehumidifier sized correctly for your space will help by drying the air and preventing new mould growth (though it won’t kill existing mould). For serious mould-prone areas, consider a higher-capacity dehumidifier that can handle the room size and run long enough to maintain low humidity. It also helps to look for extra features like an air purification filter, which can trap airborne mould spores - for example, Breville’s All Climate dehumidifier doubles as a dehumidifier-air purifier with a two-stage HEPA filter to remove allergens while it reduces humidity. Ultimately, the key is to keep the environment dry: a dehumidifier running regularly will make it much harder for mould to grow or spread.

No - a dehumidifier is not designed to cool a room like an air conditioner. In fact, running a dehumidifier will usually make a room slightly warmer, not colder. Compressor-based dehumidifiers generate a bit of heat as a byproduct (from the compressor motor and the reheating process), and desiccant dehumidifiers release even more warmth - they can raise the room temperature by a few degrees (often up to around +3-5 °C) during operation. Removing humidity can make the room feel more comfortable (less clammy or muggy) at the same temperature, but it won’t actually lower the air temperature. So if you need to cool a hot room, you’ll still need an air conditioner or fan - the dehumidifier’s job is purely to dry the air, not chill it.

Several top-rated models compete for the title of best dehumidifier in Australia, and the ideal choice depends on your needs. Leading brands like De’Longhi, Ausclimate and Breville all offer highly regarded units. In a recent consumer survey, De’Longhi was rated the number-one dehumidifier brand in Australia for overall customer satisfaction - reflecting strong performance and reliability. For larger spaces or very damp areas, Ausclimate’s NWT 35L dehumidifier is often recommended as it can remove up to 35 L of moisture per day (suitable for areas ~50 m²), making it one of the best dehumidifiers for heavy-duty home use. Breville dehumidifiers (such as the Smart Dry series) are also popular, offering smart features and easy operation that work well for bedrooms and living areas. Ultimately, the “best” dehumidifier is one that fits your room size, climate, and feature preferences - which is why Appliances Online carries a range of the best dehumidifiers Australia has to offer, all with our Price Match Guarantee and expert support to help you choose.

Yes - dehumidifiers are versatile appliances and can be used in any room where you need to remove moisture, including bathrooms and bedrooms. In a bathroom, a small dehumidifier (can sometimes be referred to as a bathroom dehumidifier) can quickly pull excess steam out of the air after a hot shower, helping to prevent condensation and mould on your mirrors, tiles and ceiling. Just place it in a safe spot away from direct splashes, and let it run until the bathroom air is dry. In a bedroom, a dehumidifier helps eliminate dampness and condensation (for example, stopping water droplets on windows on cold mornings). If you need a bedroom dehumidifier, look for one with a quiet mode or low-noise operation so it won’t disrupt your sleep. Many modern units have a “sleep” or low fan setting specifically for use in living areas at night. Remember, these devices are portable, so you can easily move your dehumidifier from the bedroom to the bathroom or any other area as needed - they’re designed to be used all around the home

Using an Ausclimate dehumidifier is straightforward. Follow these steps to get the best results:

1. Set up in the right spot: Place your Ausclimate dehumidifier in the room that needs dehumidifying, ideally in the most damp or humid area. For example, if one corner of the room has noticeable mould or condensation, position the unit there.

2. Close windows and doors: For efficient drying, keep the room relatively sealed while the dehumidifier is running. This way, you’re not trying to dehumidify the whole outdoors. Closing windows and doors will speed up the drying process and allow the dehumidifier to focus on the moisture inside the room.

3.Turn it on and adjust settings: Plug in the dehumidifier and press the power button. Set your desired humidity level on the humidistat (around 40-50% is a good target for healthy indoor air), or use the continuous mode if the space is very damp. Ausclimate dehumidifiers have intuitive controls - some models even have auto modes and digital displays that show the current humidity.

4. Let it run and remove collected water: Allow the dehumidifier to run until it reduces the humidity to your target or until the water tank is full. Ausclimate units will automatically shut off when the tank needs emptying. When that happens, simply slide out the water tank, pour it out, and slot it back in. For convenience, you can attach the continuous drainage hose (if your model includes one) to divert water straight to a drain, so you don’t have to empty the tank manually.

5. Maintain and repeat as needed: You don’t need to run your dehumidifier 24/7 once your room’s moisture is under control. In fact, after an initial deep drying of the space, you might only need to use it once every few days or week to maintain dryness. Keep an eye on humidity levels (many Ausclimate dehumidifiers have an indicator or hygrometer). Also, remember to clean the air filter periodically (e.g. monthly) and keep the air vents unobstructed - this ensures your dehumidifier continues to perform at its best.

By following these steps, your Ausclimate dehumidifier will efficiently remove excess moisture and help keep your home mould-free and comfortable. If you ever lose your user manual, Ausclimate provides digital copies and customer support to help with any specific questions.
