Performance score
Based on dust removal (50%), smoke removal (40%) and VOC removal (10%).
enter value/s in increments of i between 7 and 90
Ease of use score
Based on the model's onboard controls, its remote (if it has one), how easy it is to move around, whether it's prone to tip over, how easy it is to clean, and the quality of the supplied instruction manual.
enter value/s in increments of i between 50 and 90
Replacement filter cost per year
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. Some filters will need to be changed more than once a year, other filters will last longer.
enter value/s in increments of i between 12 and 720
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.
Shop Ethical rating
Shop Ethical rates the environmental and social impact of the company (not the product) using independent sources. This rating is not included in our total score. N/A means there is no rating for that company.
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.
enter value/s in increments of i between 10 and 95
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).
Wi-Fi 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.
