HEPA filter
High Efficiency Particulate Air (HEPA) – capable of trapping extremely small particles of dust, smoke and even bacteria and viruses. These filters need to be periodically replaced.
Charcoal filter
Charcoal or carbon filters are said to be good for trapping odours and VOCs such as formaldehyde. These can usually be washed and reused but may need to be replaced eventually.
Pre filter
A coarse filter to catch big dust particles and pet hair so that they don't clog the HEPA and other filters. These can usually be washed and reused but may need to be replaced eventually.
Ionisation filter
Generates charged particles (ions) to remove pollutant particles and microbes from the air. These filters need to be periodically replaced. Ionisation of air can produce small amounts of ozone which is a breathing irritant.
UV sterilisation
UV light can be used to kill bacteria and viruses trapped by the purifier. We haven't tested this feature.
Dust performance score
How well this model filters out dust compared to the other models on test.
enter value/s in increments of i between 5 and 95
Smoke performance score
How well this model filters out smoke compared to the other models on test.
enter value/s in increments of i between 5 and 95
VOC performance score
How well this model filters out volatile organic compounds (VOCs) compared to the other models on test. For discontinued models, this score is not comparable to scores for current models, as we changed the method for the most recent test.

Annual replacement filter cost
Estimated cost per year for replacing the filters, based on the manufacturer recommendation and assuming the best case for how long the filter is claimed to last.
enter value/s in increments of i between 35 and 224
Timer
Most models have various timer settings to run for a set number of hours. Timers might apply only to certain modes such as Night or Away (for use when you're away from the home).
Wifi app
Some models can be controlled via an app on your smartphone. The app may also show data about the amount of pollutants detected and removed.
Availability
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.
