Air purifiers are becoming a regular fixture in the home due to the latest fires in many parts of Australia, and some of them can filter smoke particles particularly well. Our industry experts comprehensively lab test and review leading air purifier brands like Dyson, Philips and Winix to help you find the best performers on the market. 

This review replaces the earlier small review we published in December 2019. Since then, we have tested more models and revised our test method to cover the Australian market more thoroughly. Due to the changed test method, we have not included results from the earlier review. Not all the earlier models were available for re-testing; we were able to include the Beurer LR300 again, which has since been discontinued.

We test models with a variety of designs and technologies but it all still comes down to how well they remove pollutants from the air and how easy they are to use. Our tests show you which air purifiers are:

  • best for dust removal
  • best for smoke removal
  • best for removing volatile organic compounds (VOCs)
  • the most energy efficient
  • the quietest
  • the easiest to use.

Note that we weren't able to test for pollen removal this time due to technical challenges. We aim to include pollen removal in future tests. Meanwhile, any model that's good at dust and smoke removal should also be effective against pollen.

Our interactive comparison tool helps you find out which brands perform the best at cleaning indoor air, and which ones have the features you want. Our Recommended list will help you quickly see which models come out on top.

    HEPA filter

    Expand to view more details.

    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

      Expand to view more details.

      Charcoal or carbon filters are said to be good for trapping odours and VOCs such as formaldehyde. Usually can be washed and reused but may need to be replaced eventually.

        Pre filter

        Expand to view more details.

        A coarse filter to catch big dust particles, pet hair etc so that they don't clog the HEPA and other filters. Usually can be washed and reused but may need to be replaced eventually.

          Ionisation filter

          Expand to view more details.

          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

            Expand to view more details.

            UV light can be used to kill bacteria and viruses trapped by the purifier. We haven't tested this feature.
