From dust and pollen to pet dander, odours and smoke, there is a wide range of factors that can affect the quality of the air we breathe – even in our own homes. While opening a window or choosing the right indoor plants can help with some issues, the best air purifiers in Australia are designed to filter out many different elements from the air we breathe at home.
In fact, research from the CSIRO has found air purifiers can improve air quality by 30-74 per cent during controlled fires, and have indicated they could be of benefit during bushfire season. What’s more, those with HEPA (High Efficiency Particulate Air) filters can even remove airborne viruses, with the Victorian government even stating: “air purifiers are a great way to ensure your home has clean air to reduce the risk of infections spread through air.”
They have also been shown to help with asthma, pet allergies, pollen and mould, as well as chemicals like VOCs – although the University of Massachusetts notes that it does depend on the filters in the air purifier. So, we’ve curated a list of the best air purifier models in Australia, based on features including the type of filtration system (or systems), airflow and different modes. We’ve also analysed customer reviews and factored them in when it’s relevant and helpful.

Tips to find the best air purifier for your home
- Check the room size requirements: Some air purifiers are only efficient in small spaces of say, 15m2, while others can purify air in a space of 100m2 or more. To put this in perspective, an average new house in Australia is around 232m2 and an average apartment is around 137m2 according to Australian Bureau of Statistics data.
- Focus on models with a HEPA filter grade of H13 or higher: This grade refers to the efficiency of the filter, with H13 one of the highest – and currently considered medical grade.
- Consider other filters: If you want an air purifier that removed VOCs (volatile organic compounds) or smells, focus on models that include charcoal filters. And if you have pets, consider one with a pre-filter or other features targeted at pet hair, dander and smells.
- Decide what other features you want: There isn’t one best air purifier in Australia because we all want different things. For example, a light sleeper might want one that’s super quiet, while someone with allergies would be more focused on the type of filtration and how often the air is filtered (sometimes referred to as the CADR or ACH). If you’re tech-savvy, on the other hand, a solid app and pre-set features might be a priority. Or other features, such as heating and cooling modes. So thinking about what’s most important to you can help you choose an air purifier that is right for your home.
Three reasons to consider an air purifier for your home in 2025
1. Health and wellbeing
Australians spend a lot of time indoors. In fact, the Australian Government states ‘it is generally recognised that Australians spend 90 per cent or more of their time indoors.’ Combine this with the fact that the average home can be up to five times more polluted than the air outside and you can start to understand why indoor air quality is an important health consideration.
Common household pollutants such as pollen, spores and dust mites can trigger various health conditions such as asthma and allergies. Even your favourite scented candle can release chemical substances such as Benzene and Formaldehyde that stick around long after they’ve been blown out. Whether you suffer from asthma or allergies, or simply a lover of scented candles (guilty), an air purifier can help alleviate your home of air pollutants.
2. Clean living
While an air purifier cannot pick up a broom and start sweeping, it can help eliminate dust particles, mould particles, and pet dander that contribute to that stale feeling in your home.
If humidity is an issue, look for an air purifier with a HEPA filter as well as cooling functionality to help fight mildew. By reducing the indoor temperature and catching mould spores through this high-functioning filtering system, you can minimise the chance of mould and mildew showing in your home.
Additionally, an air purifier can assist in the elimination of common household odours, making for a fresher and cleaner feeling home.
3. Smart living
Air purifiers with multi-functionality can help maintain air quality even when you’re not at home – never be greeted by a hot and stuffy house again. Look for air purifiers with smart technology such as WiFi connectivity, app support and remote control options. Take it one step further and find an air purifier with cooling and heating abilities. Set your perfect ambient temperature and forget.
