In hot humid summers and cold wet winters, a dehumidifier can help fix a damp home. We lab test and review dehumidifiers to help you find the best one for your home. Our buying guide will help you decide which type you need, and how we test explains our testing rigour and scoring method.
We review both main types of dehumidifier; refrigeration and dessicant. Our review will help you decide:
Most can perform well enough in hot humid conditions, but our rigorous testing sorts out which ones operate best in challenging cold conditions. We measure their real water removal rate and how much they'll cost you to run.

Desiccant models use a disc or belt of moisture-absorbing material to dry the air. Refrigeration models use refrigeration coils, similar to a fridge or air conditioner, to cool the air and condense the moisture out. See our buying guide for more information.
The rate claimed at 30-32°C and 80% relative humidity.

A filter on the air intake to prevent dust etc getting into the machine, and to help clear the air in the room.
Allows you to set the humidity level for the room.
Wheels or castors can make it easier to move the dehumidifier from room to room, but many are light enough to just pick up and carry.
For comparison, a typical conversation is carried out at about 60dB, while city traffic is measured at around 80dB.

This is a comparative rating of the model's energy consumption and how much water it extracts. An efficient model will use less energy but extract more water when compared to other models.
Our lab testers assess each model for ease of accessing and emptying the water tank, quality of instructions and labels, using the controls, mobility of the unit and ease of cleaning it.
Based on the running cost and water extraction rate in our performance testing, and on electricity cost of 25c/kWh.
A Similar model is identical in most aspects except for a few. This means that a majority of its test results are identical so you can reasonably expect to get the same results from the model we tested, but for those aspects which aren't identical, we'll note these as "Not Tested" in the Compare tables.
A Tested model refers to a model that is still current and available in the Australian market. You should be able to order this model through your local retailer, or find it online.
These models can't be found in retailers or online or are no longer manufactured. You may still find these models on second hand websites, or in second hand dealers. Test methods may change over time, so criteria which can't be directly compared will contain an N/A.
An Identical model is exactly that. Performance characteristics will be identical and the only difference will be something trivial such as colour, which won't have an impact on performance.
These are models we haven't yet tested but that are available.
