Ausclimate NWT Large 35L Dehumidifier
A powerful, family-sized workhorse that handles serious moisture and winter washing across a whole home. Our overall pick for most Australian households battling damp.
Damp is a genuinely Australian problem, even if we don't always talk about it. Coastal humidity along the Queensland and NSW seaboard, cold wet winters through Victoria and Tasmania, and closed-up apartments that trap moisture all lead to the same result: condensation on windows, musty wardrobes, mould on ceilings and washing that never quite dries. A good dehumidifier tackles all of it, and the right one depends far more on your climate and room size than on brand loyalty.
This guide draws on published manufacturer specifications, independent expert reviews and Australian buyer feedback rather than any hands-on lab work of our own. We've focused on models you can actually buy here in 2026 through Amazon.com.au and major retailers, across a AU$150 to AU$800 spread. We've deliberately mixed the two main technologies: refrigerant compressor units that shine in warm, humid air, and desiccant units that keep working when the temperature drops below 15°C.
We also weighed practical Australian factors: 230V running costs, tank size versus continuous drainage for set-and-forget use, noise in bedrooms, and warranty support you can reach locally under Australian Consumer Law. Whether you're drying a single bedroom or protecting a whole family home from winter mould, one of the five below should suit.
1Match capacity to the space and the problem. Litres-per-day ratings describe how much moisture a unit pulls in ideal conditions, so size up for whole homes, persistent mould or laundry drying, and stay modest for a single bedroom.
2Choose the right technology for your climate. Compressor (refrigerant) units are most efficient in warm, humid air like coastal Queensland and NSW summers, while desiccant units keep extracting in cold rooms and southern winters where compressors slow down.
3Decide between tank emptying and continuous drainage. A larger tank means fewer trips, but for basements, laundries or all-day running, look for a continuous drain hose outlet so you can set and forget.
4Prioritise a built-in humidistat and auto modes. Setting a target humidity of around 50-60% stops the unit over-drying and cuts running costs, and a dedicated laundry mode is genuinely useful in wet Australian winters.
5Weigh noise and energy use. Compressor units cycle a fan and pump, so check noise levels for bedroom use, and remember these run on 230V mains, so a lower wattage and a timer meaningfully affect your power bill.
6Consider portability, filters and warranty. Castors and a carry handle help you move a unit room to room, washable filters lower upkeep, and a clear Australian warranty with local support matters under Australian Consumer Law.

Editor's note
Our rankings draw on published specifications, independent expert reviews and Australian buyer feedback rather than our own hands-on testing. For most homes we'd match the technology to your climate first and capacity to your space second, since a compressor unit in a cold room or an undersized unit in a damp home will always disappoint. Prices and stock shift often in Australia, so confirm the current model and capacity with the retailer before you buy.
Frequently asked questions
What size dehumidifier do I need for an Australian home?
It depends on room size and how damp the space is. A single bedroom or bathroom is usually fine with a compact 10-12L per day unit, while whole homes, persistent mould or laundry drying are better served by a larger 30L-plus compressor such as the Ausclimate NWT Large 35L. Rooms with heavy condensation or coastal humidity generally need more capacity than the floor area alone suggests.
Compressor or desiccant dehumidifier for the Australian climate?
Compressor (refrigerant) units are most efficient in warm, humid conditions, so they suit coastal Queensland and NSW and summer humidity well. Desiccant units keep working effectively in cold rooms and southern winters below about 15°C, making them the better choice for Tasmania, Victoria and unheated spaces. Many Australians in mixed climates simply pick based on when their damp is worst.
How much does it cost to run a dehumidifier in Australia?
Running cost depends on the unit's wattage, how many hours it runs and your electricity tariff. On 230V mains, a smaller compressor unit typically draws a few hundred watts, so using a humidistat, a timer and a target of around 50-60% humidity keeps costs down by avoiding unnecessary running. Desiccant units are effective in the cold but generally use more power per litre of moisture removed.
Will a dehumidifier help with mould in my home?
Yes, reducing indoor humidity to around 50-60% makes it much harder for mould to grow and helps dry out damp walls, wardrobes and bathrooms. A dehumidifier controls the moisture that mould needs, but you'll still need to clean existing mould and address any underlying leaks or ventilation problems for a lasting result.
Are dehumidifiers covered by warranty and Australian Consumer Law?
Dehumidifiers sold in Australia come with a manufacturer's warranty and are also covered by Australian Consumer Law, which provides consumer guarantees that a product is of acceptable quality and fit for purpose regardless of the stated warranty period. Buying from local brands or major retailers generally makes support and any repairs or replacements easier to arrange.
