Sticky, wet and humid weather can very quickly dampen both your home and mood.

It can also lead to an onslaught of mildew and mould that doesn't just look terrible, but can become a health risk too.

That’s where a dehumidifier comes in.

Unlike a humidifier, which adds moisture to the air, a dehumidifier works to draw in warmer air currents and expel cooler, drier air.

Not only does this make for a drier, less musty home, it can also mean a reduced airconditioning bill, less air pollution and, in some cases, less severe allergies.

With plenty of dehumidifier models to choose from, we’re here to help you narrow down your options so you can reap the benefits sooner.

To help you remove the dampness from every part of your home, we’ve rounded up nine of the best dehumidifiers for Australians, based on real customer reviews and our own knowledge of the products.

Tenergy Sorbi 1000ml Air Dehumidifier, Amazon Australia, $230.45

If you’re looking for a truly compact dehumidifier, this little option from Tenergy is sure to fit the bill. The ultra-quiet unit is the ideal size for smaller spaces, making it a great option for those who don’t have proper ventilation in their bathroom or laundry. One reviewer even said it was “actually one of the best investments” they made for their home.

With a HEPA air purifier function, the Sorbi can purify air while removing excess moisture at the same time, which is a great add-on for a model in this price range. It also features an LED indicator, auto-shut off, a water level sensor and an extremely portable 2.72kg design.

It does only remove 750ml of water per day, so you will have to empty it regularly, but it’s still a handy option for using in short bursts.

DeLonghi Tasciugo AriaDry Multi Dehumidifier, The Good Guys, $469

With its 4.5 star rating on The Good Guys website, DeLonghi’s Tasciugo AriaDry Multi Dehumidifier is a top option for those with larger homes. Able to remove a whopping 16L of excess moisture within 24-hours, the model is ideal for areas prone to high levels of humidity.

Fitted with a double filtration system, the AriaDry contains both a dust filter and a removable filter that is made to capture various allergens, which means it can also help to improve overall air quality in your home.

With its dedicated laundry function, continuous draining system and relatively portable size too, the DeLonghi dehumidifier is a great all-rounder at a reasonable price.

A customer commented, “It’s amazing how much water this dehumidifier is able to ‘suck out of the air’, a much better result than I had expected!”

Some reviewers also agreed they “should have purchased one years ago”.

AusClimate Cool Seasons Premium 10L Desiccant Dehumidifier, Appliances Online, $501

With its 10L capacity, the AusClimate Cool Seasons Premium Dehumidifier is a compact and lightweight, yet powerful option. Unlike others on this list, the dehumidifier is specifically made for cooler climates, and has the ability to remove moisture from the air for temperatures as low as 1°C.

The all-in-one dehumidifier and dryer is also fitted with a laundry mode to help you dry clothes faster in cooler weather and has a nano silver filter which is made to kill bacteria on contact. Additional features include a 12-hour timer, a 3L water tank, an auto-restart function and a continuous draining system.

One five-star reviewer on Google Reviews even went as far as to call it “life changing,” saying, “We have drawn litres of moisture from our cold damp house and it is now feeling warmer and much drier, the musty smell has almost disappeared... and there is no moisture inside on the windows in the morning after only two days.”

Ionmax ION610 Desiccant Dehumidifer, Catch, $298

If you’re looking for a dehumidifier with a slightly smaller capacity, the Ionmax ION610 comes extremely highly rated. Removing up to six litres of moisture per day, the unit boasts a 1.8L tank and a dedicated ‘laundry’ mode to help you dry clothes faster indoors.

Weighing in at just 5.1 kgs, the ION610 is able to be moved from room to room with relative ease, making it a top option for keeping your entire house dry. It also runs at low noise levels of 34-45 dBA, which isn’t always the case for smaller machines.

The dehumidifier’s water tank is designed with a water level indicator and includes a hose so you can run it with a continuous drainage option, which is an extremely handy addition. It also features an antibacterial air filter, three power settings, four preset relative humidity levels and a timer that can be set for up to eight hours at a time.

“This little piece of dynamite has made such a difference to my home,” one person wrote.

“We use a gas heater and had condensation dripping like rain. My place was cold due to all the vapour. In days, we managed to draw out 18 litres of water. Highly recommend.”

Need something compact? This Arovec dehumidifier can remove up to 300ml of water every day, making it suitable for home offices, small bedrooms and caravans.

It has a built-in thermoelectric cooling technology that supposedly allows it to run without a compressor, plus it operates quietly at below 30dB (similar to a whisper).

Online reviewers agree it’s a bargain, with one person commenting: “Super quick delivery. For a small & very affordable dehumidifier it works well.”

Breville The All Climate Dehumidifier, Betta Home Living Australia, $499

Made for both cold and warm environments, Breville’s The All Climate Dehumidifier is an ultra-efficient model made for medium-sized rooms and difficult-to-control areas like bathrooms or laundries.

It has a two-stage air filtration system which includes both a pre-filter and a carbon filter to reduce dust, pet dander, odours, smoke and other airborne allergens, so it’s great for those with asthma or seasonal allergies.

A Sensair System meanwhile allows you to keep the humidity levels within your comfort zone by setting your preferred level and leaving it do the rest.

The dehumidifier is able to capture up to eight litres of water per day and also features a laundry mode that can be used both to dry clothes faster and to help dry off wet carpets and rugs.

Ionmax Dehumidifier ION612, Bing Lee, $469

Boasting an impressive five out of five star rating on the brand’s website, Ionmax’s ION612 is able to remove up to seven litres of moisture from the air per day, making it a great dehumidifier for medium-sized rooms.

The controls at the top of the unit are easy to use, with the panel including a convenient eight-hour timer and a laundry function which helps to dry your washing indoors. Weighing around six kilograms, the ION612 is also fairly lightweight and includes a fold-down carry handle to increase portability.

Additional features include a continuous drain option that allows you to keep it running without having to continuously empty the water tank, and a three-directional adjustment for expansive room coverage.

Dimplex GDDE50E Dehumidifier, Appliances Online, $559

For larger spaces, this dehumidifier can collect up to 50 litres of moisture per day. It comes with three preset modes, including Bedroom, Living Room and Continuous, plus electronic controls so you can adjust the relative humidity levels to anywhere between 30 per cent and 80 per cent.

The freestanding model also has a 24-hour timer, allowing you to program the appliance to automatically turn on at a time that suits you. Other features include a filter wash reminder, child lock, and carry handles and castors for easy portability.

One customer wrote,“ I live in a rental property with a damp problem. The problem improved so much since I’ve bought this machine. Happy that I bought it!”

DeLonghi Pump System Dehumidifier, Appliances Online, $559

If you’re having trouble finding a place in the room to attach the hose for the dehumidifier, which allows the condensation water to flow outside, then you might want to consider this DeLonghi model. Its Heavy Duty Pump System and 5m hose apparently makes it easy to get rid of excess moisture, even where there are tall items that would otherwise make it inconvenient to install or restrict the amount of space the unit can dehumidify.

“We have used continuous drain dehumidifiers in the past. However, the pumping function makes this unit far more useful,” one reviewer posted.

Another person commented: “We had a water leak in our lounge and insurance wouldn’t cover it and this unit saved us days of hiring or paying professionals.”

This DeLonghi dehumidifier removes up to 30 litres of moisture per day and has a washable anti-dust filter to remove pollutants and allergens, helping improve the air quality.

WHAT TO CONSIDER BEFORE BUYING A DEHUMIDIFIER

While a dehumidifier can be a great investment, there are some factors you’ll want to consider before making a purchase.

Dehumidifiers come in a range of different sizes and capacities, making it relatively easy to find one to suit your needs. Generally speaking, dehumidifiers come in three sizes: large, medium and small, with capacities starting at around 500mL per day and ranging up to around 40L per day.

Larger capacity models are often quieter and more energy efficient, though tend to be bigger and heavier as well as more expensive. Smaller capacity models are more budget-friendly and more suitable for smaller areas such as bathrooms, but the trade off is that you’ll get less features, less efficiency and a smaller water tank.

Speaking of water tanks, you’ll want to look for a dehumidifier with a capacity of 4L or more if you want to avoid emptying it frequently. As a bigger tank equals a bigger, heavier dehumidifier though, you’ll need to weigh up portability and the size of your space with the convenience of a larger tank size.

You can also look for models with a hose output, which will allow you to run a hose from the unit to a drain or a sink for continuous draining.

While usually found on pricier models, a humidistat is a convenient feature worth looking out for. If your humidifier comes with this feature, it means you can set the target relative humidity for the room to make it as comfortable as possible.

If you want to keep your dehumidifier running with minimal effort, try looking for a model with an auto-restart function. After a power outage, these dehumidifiers will start themselves back up again so you don’t have to lift a finger.

WILL A DEHUMIDIFIER HELP AFTER A FLOOD?

While a dehumidifier may not be able to save your home completely, it can help to dry out flood-affected rooms and move air around to stop condensation and mould from forming. The time it will take to dry out a room after flooding will ultimately depend on the size of the flood, how porous the materials are that you are trying to dry out and the current humidity level.

It is recommended that you continue to run your dehumidifier until all porous surfaces are completely dry to prevent mould from forming. This can take anywhere from a few hours to several weeks, depending on the water level and the capacity of your humidifier.
