A dehumidifier is an appliance that helps remove moisture from the air in any room. It helps decrease humidity, making your home feel more comfortable. It has a fan and cooling coils that suck in air and remove the moisture.
Dehumidifiers are particularly helpful if your household has a musty smell, water damage on walls or mould in humid rooms. It can also help reduce symptoms of asthma and allergies, allowing you to breathe easier.
To find the best dehumidifier for your home, you need to consider a few factors like room size, your environment's condition, the appliance's tank size and water removal rate. For added convenience, you can opt for dehumidifiers with air filter and UV filter functions.
For this list, we evaluated numerous dehumidifiers found in various online retailers, including Amazon, Appliances Online and Harvey Norman. We picked models based on customer reviews and ratings. We also chose the units for each category based on key product features, such as value for money, tank capacity, water removal rating and added functions.

Dehumidifiers are a dime a dozen but for something that's tech-savvy and works practically everywhere you can't go past The All Climate. Suitable for warm and cool environments, it's received a 4.8-star customer review rating on Appliances Online and a perfect 5-star rating on Bing Lee.
Capable of extracting 8 litres of water per day, it's best for small to medium rooms of 25–50m2 and comes with a built-in handle to transport it from room to room as required.
Under the hood is a Sensair System that lets you dictate your ideal humidity (40%, 50% or 60%) and works to keep it on target. For allergy sufferers, a pre-filter collects dust and pet dander while negative ions work as a second filter, attracting allergens and smoke in the air.
"The Breville dehumidifier is slimline, easy to use and efficient," said one The Good Guys customer. Others were happy over how quiet it is and how well it works.
At sub-$400 it's quite affordable. There's also a 2-year warranty to give you enough time to really put it through its paces during the rainy months. The main gripe customers have is that the tank is quite small and requires emptying throughout the day. Some find this inconvenient while others say it's a better alternative to lugging around a large and heavy tank.
In the 2023 Finder Retail Awards, we surveyed over 34,000 Australians about their retail purchases to discover which were their favourite brands across 170 product categories and over 1,200 total brands.
For dehumidifiers, Breville was ranked 11th for value for money, 11th for performance, 9th for ease of use, 12th for cleaning and maintenance and 10th for product features.
12 brands were rated across these decision criteria.
For the best desiccant option, we recommend the Ausclimate Cool Seasons Premium 10L Desiccant Dehumidifier. It has an average rating of 4.9 out of 5 stars on Appliances Online and Harvey Norman.
This dehumidifier can extract up to 10 litres of excess moisture per day in a room size up to 50m2. It has a nano-silver filter to keep the room dry and fresh. It also has a removable 3-litre water tank with an anti-spill water bucket design and a continuous drainage feature for easy maintenance.
Suitable for bedrooms, basements and living areas, this desiccant dehumidifier has a 12-hour timer and a laundry function for drying clothes. It is easy to operate and has a modern design to fit any home aesthetic.
Customers said it has a near-silent operation, making it a great option for night use. It's a bit difficult to move around, but this doesn't seem to bother most buyers.
Ionmax's Dehumidifier ION612 is our pick for the best bathroom dehumidifier. On Amazon and Appliances Online, it has an average rating of 4.35 out of 5 stars.
This appliance has a built-in ioniser and silver nano technology filter that help kill bacteria on contact, improving air quality in your home. It can extract up to 7 litres of excess moisture a day at 20°C. When the tank is full, its indicator lights up to avoid spillage.
While this has a small footprint, the Ionmax Dehumidifier ION612 packs a punch. It has tons of features comparable to higher-end models. You can use its laundry mode to dry clothes in no time. It also boasts of stable performance in both low and high temperatures, from 1°C to 40°C. The fold-down carry handle makes the unit easy to move around as well. One con for buyers is that it gets quite noisy when left on for extended periods.

Large spaces such as commercial properties, construction sites and basements require a dehumidifier with strong performance, a large tank and hose drainage. The Sleavon 130 Pint Commercial Grade Dehumidifier ticks all those boxes.
A fantastic option to take care of extensive water damage issues, the Sleavon uses fast airflow to remove up to 74 litres of moisture across an area of 550m2 per day.
You can hook it to an outlet with the included 2-metre flexible tube for continuous drainage. Alternatively the water tank can take up to 5.5 litres and will automatically shut down when full to prevent water overflow.
An inbuilt 24-hour timer lets you set it overnight ready for work the next day while the auto ON/OFF helps to maintain a constant room humidity of between 20% and 90%, depending on your needs.
Highly durable, the Sleavon features a rugged metal shell and a labour-saving handle and large caster wheels to move it between locations. Priced at over $2,000 it's a big investment, but one well worth it if you're trying to stamp out bad mould and mildew in a large area.
We recommend Tenergy's Sorbi 1000ml Air Dehumidifier w/Air Purifying Function as the best air purifying dehumidifier. On Amazon, it has a rating of 4.4 out of 5 stars from over 1,000 reviews.
The Sorbi 1000ml Air Dehumidifier is a compact and lightweight option for small spaces. It is quite affordable but offers heaps of functions seen on more expensive models. It uses Peltier technology and HEPA filtration to make the air cleaner. It also has a removable 1-litre water tank and can extract 750ml of excess moisture per day.
This is a great choice for bathrooms, closets and other small areas. It helps capture small particles that can cause allergies and irritation. It has a relatively quiet operation and a small footprint to fit in any area of your household. Additionally, it is certified by the Energy Technology List (ETL).
Ausclimate is one of the top-awarded dehumidifying brands on productreview.com.au. Its products are built for the Australian environment, come with a 2-year warranty and are sensitive-choice approved by the National Asthma Council.
Of its smaller models the Cool Seasons Premium 10L Desiccant Dehumidifier is lightweight and powerful. Add a 4.8-star review rating on Appliances Online and you've got a portable dehumidifier that won't let you down.
Perfect for medium rooms of up to 50m2, the Cool Seasons Premium measures a tidy 499mm x 317mm x 213mm so it won't take up heaps of space. Weighing in at 6.8kg, it's extremely lightweight and although it doesn't have wheels the in-built handle makes it a cinch to move about.
The water tank has a capacity of 3 litres and is located at the front for quick manual emptying. For heavy moisture, a hose attachment allows for continuous drainage, emptying whenever the tank reaches 10 litres.
A nano-silver filter kills viruses and bacteria for cleaner air and the handy laundry mode helps speed up indoor clothes drying to avoid musty clothes when sunny days are few and far between.
"This dehumidifier really surprises me in many good ways," said one Appliances Online reviewer. "Its lightweight structure, user-friendly functions and the dehumidification outcome [is] worth every cent I spent."
For bedrooms, we chose the Dimplex 25L Portable Dehumidifier with Electronic Control as the best option. It has a rating of 4.6 out of 5 stars on Harvey Norman.
This unit can remove up to 25 litres of excess moisture a day, suitable for bedrooms, basements and living areas. It has electronic control and a digital display for ease of use. Apart from a 24-hour timer, it has 3 pre-set modes: continuous, living room and bedroom.
The general sentiment is that this is an affordable yet powerful dehumidifier with a large water tank capacity. Its electronic control lets you modify the humidity in your room. It has filter-wash and tank-full indicators, so you won't have to worry about spillage. The carry handles are comfortable to grip and make moving the unit around effortless. However, its continuous drainage function requires a 12mm hose, which isn't included in the package.
In the 2023 Finder Retail Awards, we surveyed over 34,000 Australians about their retail purchases to discover which were their favourite brands across 170 product categories and over 1,200 total brands.

High humidity in cars can cause foggy windows which can be a safety hazard on the road. A UV-breaking windscreen can help reduce this. As can a car dehumidifier. These typically come in the form of a bag filled with silica pellets and one of the best regarded comes from the brand Pingi.
With over 16,000 positive reviews on Amazon it's our winner for the best car dehumidifier you can buy in Australia.
Available in a 299g pouch it can absorb 120ml of liquid. Simply pop it on your dashboard for effective removal of condensation. When fully saturated, it can be quickly refreshed by popping it into the microwave for 6 minutes and letting it steam off.
A colour indicator warns you when it's reaching capacity, turning from blue to pink, so you'll never be caught out. And, the pouch can be used for years making it well worth your coin.
According to Lean Metrics the average dehumidifier has a noise level of 60dB. Anything 50dB or lower is considered quiet. With a minimum noise level of 40dB the De'Longhi DEXD216F 16L Aria Dry Dehumidifier is up there as one of the quietest units you can get.
This sleek machine has an adjustable humidistat to keep your room's temperature and humidity how you like it.
The 2.1-litre water tank capacity is on the smaller side of things and may see you emptying it multiple times per day which could be inconvenient for some. To help, a transparent water tank keeps you on top of its performance and a simple pull system makes emptying it a seamless experience. Alternatively, if you prefer to run the Tasciugo overnight or while at work there's a continuous drainage option.
A double filtration system improves air quality by filtering out dust and allergens. Also, similar to other dehumidifiers, there's a laundry mode for drying clothes indoors.
Customers were impressed by how effective it is at collecting moisture, how quiet it is and how easy it is to use.
Mitsubishi Electric's Oasis Pure 38L Dehumidifier is our pick for the best large capacity option. It has a rating of 5 out of 5 stars on Harvey Norman.
With a convenient timer mode and multi-stage air filtration set-up, this Mitsubishi Electric unit is easy to use, removing up to 38 litres of excess moisture per day. It has a handy laundry function when you want to dry clothes while eliminating mildew in your home. It also features a PM2.5 filter and a pre-filter to remove smoke, odour and other common fine particles.
Apart from its large capacity and convenience, numerous buyers were impressed by this appliance's durable build and functionality. It has an adjustable louvre, so you can select the direction of the airflow. It also has a permanent draining option for continuous use. Unfortunately it is quite heavy at around 20kg, which could make moving it a bit of a challenge.
For large, damp basements a commercial dehumidifier such as the Sleavon mentioned above is a great machine to stamp out dampness. But with a price tag of $2,000 it's an expensive investment that not everyone can afford. A cheaper option that's still effective in large areas is the Olimpia Aquaria.
Effective in areas of up to 100m2, it has a sizeable water tank of 6 litres and is able to suck up to 24 litres of moisture out of the air in a day. A triple filtration system consisting of a HEPA filter and activated carbon filter really kicks things up a notch, capturing dust, pollen and microparticles and absorbing unpleasant odours such as mildew.
Wi-Fi connectivity allows you to control the Aquaria from anywhere in the house (or outside the house) via an app so you won't have to wander down the stairs to change its speed. Additionally, there's a timer to let you run it while you're asleep or at work to keep noise disturbances at a minimum.
For safety, there's a child lock, a full tank alarm and an automatic shut-down when full to prevent water overflow.
A major issue is that there's no continuous drainage so you will need to manually empty. Depending on how damp your basement is, this may be less than ideal. However customer reviews are excellent with one stating that they only need to empty it once daily.
Costing a tidy $150 and boasting a customer review rating of 3.9 out of 5 stars on Amazon across over 600 happy customers the Laover Dehumidifer works a charm without giving your wallet too much of a workout.
Suitable for rooms of 26m2 it's great for studio apartments and small homes and can absorb up to 450ml of moisture daily. There's no handle or wheels but at 1.3kg it's small enough to transport from room to room and to place on desks or shelves to stop moisture in its tracks.
Choose between 2 working modes, depending on your needs. Powerful for when you need to get humidity down in a jiffy and ultra quiet for overnight running which pulls noise levels to a whisper-quiet 30dB.
The auto-shut-off mode when the tank is full ensures no water overflow or damage to your home and as a fun little addition it has 7 colourful LED lights which you can set on rotation or fix to add atmosphere to the room.
De'Longhi's Laundry Function has been called out by its customers time and time again for how effectively it dries clothes indoors. In fact, one Bing Lee reviewer says it's "better than a clothes dryer" as it uses less power and doesn't damage your clothes like a dryer does.
Switch to the Laundry Function and the Tasciugo AraDry Multi automatically optimises its ventilation speed and dehumidifying capacity to remove moisture from clothes leaving them dry and smelling fresh.
The 2.1-litre tank capacity is more than enough to handle a load of washing or to banish must from the wardrobe. And running it overnight won't cause a disturbance with a quiet noise rating of 40dB.
Whether you're drying clothes in the closet or in the living room, the Tasciugo AriaDry Multi Dehumidifier covers a generous 65m2 space.
When done, use the integrated handle and wheels to manoeuvre in into another space for storage or to dehumidify your home.

13For this list, we examined various dehumidifiers listed with online retailers like Amazon, Appliances Online and Harvey Norman. We evaluated models from the following brands:
We shortened our choices based on customer ratings and reviews (as of March 2022). We also considered each model's key product features, including size, coverage, value for money, tank capacity and water removal rating. We came up with what we believe are the 11 best dehumidifiers available right now in Australia.
A dehumidifier is a type of appliance that removes moisture from the air in a room. By removing moisture from the air, the dehumidifier decreases humidity and makes a room feel more comfortable.
Residental dehumidifiers are available at most home appliance stores and online marketplaces. This includes:
Most dehumidifiers work in the same basic way. The dehumidifier uses a fan to suck in air. As this air moves through the dehumidifier it passes cooling coils, which remove moisture from the air. This air is then reheated and redistributed back into the room. The moisture is collected in a tank or reservoir that you can remove to empty. Most dehumidifiers will shut off when the water tank is full to prevent overflow.
Desiccant dehumidifiers have a desiccant wheel that attracts water from the air. This moisture is collected in a silica gel and is released as dry air when the wheel is heated.
Desiccant dehumidifiers are generally quieter than compressor dehumidifiers. As they expel dry air they're best if you wish to maintain a low humidity home.
If your home has any of the following warning signs, you should consider getting a dehumidifier:
An effective dehumidifier can do the following:
A dehumidifier typically costs between $140 and $1,000. Choose a dehumidifier based on the size of your room or home and the humidity and temperature of your environment.
If you want to remove moisture from individual small rooms there are many affordable models available. At the higher end of the market are dehumidifiers with a larger capacity to work in large rooms, open spaces and even entire apartments and houses.
There are 2 main types of dehumidifiers – desiccant models and refrigeration models. If you live in a cold, damp climate, a desiccant dehumidifier will be more effective because it won't cool down the room. If you live in a hot, humid climate a refrigeration dehumidifier is a more effective option.
The effectiveness of a dehumidifier is measured by how much water a dehumidifier can remove from the air in a 24-hour period. A typical dehumidifier removes from 7–25 litres of water per day.
Small dehumidifiers can usually hold around 2–4 litres of water and might need to be emptied daily or even multiple times per day. Large models hold more water so you don't need to empty them as often, but they cost more and can be difficult to move or carry.
When comparing dehumidifiers, look for the following additional features:
Air conditioners work similarly to dehumidifiers by removing moisture from the air. The difference is that in addition to performing this essential function, air conditioners also make the room colder or hotter. A dehumidifier can't cool your room down on a hot day like an air conditioner can, but it will be more cost-effective to run. If your house is cold and damp, a dehumidifier will get the job done. If your home is hot and humid, you might want to use the dehumidifier with a ceiling fan or use an air conditioner to cool your room while getting rid of moisture.

It's the dehumidifier you need when you don’t need much dehumidification.
It dehumidifies and does nothing else – and I respect that.
