Finally removing that 70s trippy wallpaper in your home might have an impact on your wellbeing. For another at-home wellbeing boost that doesn’t involve physical labour, consider an air purifier. The best air purifier does 1 thing well: removes tiny particles from the air that can be irritating, especially to your lungs. Compact, or easy to move, it’s quiet and simple to use. We’ve scoured the web to bring you the top air purifiers in Australia, backed by real Aussie consumer insights.
7 Best Air Purifiers in Australia
What does an air purifier do?
An air purifier is intended to improve indoor air quality. It does this by minimising pollutant sources like cigarette smoke, dust and pet dander. Many people who use air purifiers do so because they want to ease asthma or allergies, or to sleep better. But there’s little medical evidence that air purifiers help to relieve respiratory symptoms.
Air purifiers with HEPA (High Efficiency Particulate Air) filters can purify the air better than non-HEPA filters. That’s because they’re very good at removing fine particles from the air, including dust, pollen, mould spores, exhaust soot and smoke. However, they don’t catch gases or any larger allergens, like dust mites and pet hair, that can remain in the environment even after the air’s been purified.
Because your home isn’t airtight and particles are constantly being drawn in through windows, doors and more, to be most effective your air purifier needs to run 24/7. So, pay attention to the energy usage of your air purifier. Plus, you need to regularly change your air purifier’s filter. Be sure you know the cost of the replacement filters so you can factor that into the ongoing running costs.
There are no regulations that air purifiers legally need to meet before they go on the market, unless they claim to have a true HEPA filter – see below. But one way of feeling confident that an air purifier performs well is to choose one that’s got the approval of the National Asthma Council Australia’s Sensitive Choice programme. This programme helps consumers identify asthma- and allergy-friendly products. Six out of seven of our air purifiers have this backing.
If you’re wondering whether you need an air purifier, humidifier or dehumidifier, there’s a great infographic on the Sensitive Choice website. Basically, if you’re worried about mould, try a dehumidifier or humidifier to help maintain the best moisture levels in your home. Air purifiers don’t prevent mould growth – you need to remove the moisture that’s allowing it to grow. Check out our guide to Australia’s best humidifiers.
Important features to consider
These are the key features that every air purifier should have.
Adjustable speed settings allow you to choose the right fan level for the room – lower when you’re sleeping or working, higher when pollen season kicks in.
With most air purifiers working best in 1 room, choosing a light and compact purifier with a decent carrying handle means you can move it around easily.
What you get if you spend more
We found the more you spend, the more features you get. Apart from the HEPA filter, which we think is worth the extra expense if you’re serious about pure air, we reckon most of these are nice to haves.
LED display or apps
Want to know what temperature the room is or what the particle level is? Look for LED displays or apps that’ll provide you real-time reporting. Which, to be honest, you don’t really need.
If you don’t want to run your air purifier 24/7, or you’re likely to forget to turn it off, opt for a timer. This allows you to set it to run for a certain amount of time, like 1 or 8 hours.
If an air purifier claims to have a true or absolute HEPA filter, they must be tested and meet a specific standard. To know whether your air purifier’s HEPA filter is legit, look for their serial number and test results that should be printed on the filter. They must have been proven to trap at least 99.97% of particles of 0.3 microns.
True or absolute HEPA filters are usually more expensive than other ‘HEPA’ filters but you know that a true or absolute one has been proven to perform at a high standard. Five out of seven of our picks have true HEPA filters.
If you’ll use your air purifier in your bedroom, a night mode can be a handy feature. It’ll dim any lights and use the quietest setting.
Don’t want to move across the room to adjust your air purifier? Get one with a remote.
For maximum results, and no manual input, look for auto modes. These automatically adjust the fan speed according to the dirt or dust levels in the air.
A washable and reusable pre-filter collects large particles which can help extend the life of the main filter. Because it’s reusable, it’ll also save you money on the long-term running costs.
Filter replacement indicator
To ensure your air purifier always works effectively, a filter replacement indicator will let you know when to replace the filter.
