Air purifiers help curb indoor air pollution using a filter (or a combination of filters) to give you fresh, clean air to breathe, creating a healthier atmosphere.
Several models of these compact, portable, quiet, and easy to use appliances are available for purchase, which is why we’ve done the hard work of picking the best air purifier Australia has to offer for you. Let’s take a look!
The Best Air Purifiers in Australia in 2022
Before we dive into the world of air purifiers head-on, here’s a list of our top three picks:
How we Picked
People are quickly realising the benefits of buying an air purifier which, in turn, has recently, been causing a steady increase in their demand.
However, as there are several brands that offer different models, choosing among them can be difficult – so here are the features that you need to consider when purchasing the best air purifier for your home:
Try looking for models that offer a good range of fan speeds.
It’s important to have a powerful airflow as well as gentle airflow. While the former helps to clean a room’s air quickly, the latter is suited better for sleeping during the night. The oscillating motion of the fan can also be useful to give you greater room coverage.
You need a fan to ensure good air circulation while the purifier runs. Otherwise, the appliance will only clean the air surrounding itself, while the other parts of the room will remain polluted.
Top Tip: If you cannot find a suitable purifier that has a good range of fan speeds or a model with a fan at all, you can install either a pedestal fan or a ceiling fan in the room to help circulate the air.
The size of the air purifier is important to determine whether or not it will be a good fit for your room.
To find the answer, think about the space you want to place the appliance in – do you want to purify the whole house or just a room – maybe two?
Take measurements to determine your coverage area. Afterwards, you can compare the room size against the recommended circulation rating on the air purifier.
In most cases, you can following list as a guideline to determine the right air purifiers size:
- Small: Best for personal space or rooms up to 27 square meters.
- Medium: Best for rooms between 28 to 64 square meters.
- Large: Best for rooms between 65 to 177 square meters.
A few air purifiers can cover your whole home, so if you want, you can also look into these options as well.
Wi-Fi Apps and Remote Control
Brands offer additional features along with their models to increase its appeal to potential buyers. While some air purifiers come with remote control, some can be connected to a Wi-Fi network and controlled via a smartphone app.
A few appliances can also give you an analysis of your air quality where you‘ll be able to learn of the different pollutants it has removed from your home.
Finding air purifiers models that use this smart technology can be very convenient. Although you might have to pay more, it’ll be well worth it.
Timers and Sensors
We’ve tried to include air purifiers with air sensors as these can actively monitor the level of indoor air pollution in your home and display information to you.
Some of the models activate themselves automatically once pollution reaches a certain level. This can be great for maintaining good air quality without the appliance running constantly.
A simple timer function can be a good alternative for automatic sensors. This way, your unit will run only certain times of the day without you having to manually set it.
There are different types of air purifiers, each trying to cater to a different function. At the moment, you can choose from five different types of air purifier filters:
- HEPA filters
- Ozone filters
- Ionic filters,
- Carbon filters
- Ultraviolet filters
You can also purchase multi-purpose air purifiers that have more than one filter. As you might’ve guessed, these are more powerful in comparison to the regular ones.
Cost of Filters
Often neglected, but one of the main costs you should look at for an air purifier is its replacement filter cost. Different filters have different life spans, which creates a need for them to be changed accordingly. Also, most air purifiers have a ‘Filter Light Indicator’ to let you know when it’s time.
This replacement cost will vary depending on the brand and whether or not you opted for higher-quality filters, which is what asthma and allergy patients should go for. Budget filters are best for general use.
You have to leave your air purifier on most of the time (if not 24/7) for efficient operation. This means the appliance should be quiet. Otherwise, you’ll be listening to the noise it creates whenever it’s switched on.
Our tip would be to look for air purifiers meant for larger spaces. You’ll be able to put it on a low setting, which will reduce the level of noise considerably.
Best Air Purifiers in Australia – Our Picks
After reviewing several air purifiers available on the Australian market, we concluded that the Ausclimate Winix Ultimate 5 Stage AUS-9500 tops our list of the best air purifiers available in 2022.
As the name suggests, it has a five-stage filtration process that enhances its trapping capacity of airborne allergens and irritants. In addition to this, it also has a washable antibacterial pre-filter, a washable activated carbon filter, and a HEPA filter.
With the help of the HEPA filter, this air purifier can trap 99.97% of airborne pollutants – some as tiny as 0.3 microns. This, in combination with the nano-mesh anti-bacterial shield, helps to neutralise viruses and bacteria on contact, while the activated carbon filter captures chemical vapours.
Also, the pre-filter helps to capture larger airborne pollutants.
It uses the patented PlasmaWave™ technology. According to Ausclimate, this patented technology can utilise harmful viruses, bacteria, odour-causing compounds, VOCs and other chemical vapours and gases by creating negative and positive ions. During this, no harmful ozone is created and instead, you’re left with only fresh air. The anti-bacterial nano-mesh shield further enhances this process.
As per our recommendations in what to look for, the WINIX ULTIMATE 5-stage air-purifier also has several sensors. It comes with automatic dust and odour sensors to keep an active check on dust particles, odour, and gases. There’s also an auto mode smart sensor that allows you to ‘set and forget‘ your air quality control.
When you click on the light sensor, the ‘sleep mode‘ is automatically activated at night time that dims the panel lights for unobtrusive and quiet operation.
Adding to the efficiency is the timer feature. There are three timer options: 1, 4, and 8 hours – you can select one according to your suitability. This will be useful if you don’t want your purifier running 24/7.
In addition to being lightweight, it has a modern design that should make it an acceptable addition to most homes. It has four fan speeds including a turbo mode to improve the air quality quickly, but works best for rooms that are around 26 square metres.
The ‘Replace Filter’ indicator lets you know when to replace the air filters that keep the running efficient. This does away with the need to constantly keep inspecting them.
The Ausclimate Winix Ultimate 5 Stage AUS-9500 is approved by the Sensitive Choice Programme, which encourages companies to produce products that are more asthma and allergy aware. The Association of Home Appliances Manufacturers (AHAM) has also certified its clean air delivery rate.
You get all the above features, a remote control, and a two-year warranty at a price of AU$699.
This isn't exactly cheap, especially considering the room coverage provided. Nevertheless, the exclusive technology and several effective features make this air purifier a standout performer. You’ll be able to breathe in a better space, without having to compromise on your convenience.
Runner Up Pick: Dyson Pure Cool Tower Fan
When you compare the purifying power of the Dyson Pure Cool Tower Fan with our top pick, it falls short – though only just.
The appliance makes the allergy season seem less frightful with its smart technology that analyses the air before getting to work.
While the device itself only has one button, you can manage the device settings using a remote control. Overall, the Dyson Pure Cool Purifying Fan is very easy to operate and user-friendly.
This air purifier calculates the number of pollutants that are present in your home and then adjusts itself automatically to kickstart the filtration process. It offers 10 fan speeds with sealed HEPA and activated carbon filters to improve air quality levels in your abode.
Another useful feature of the appliance is the Smart Sensor. It can change the fan speed to match the environment as a response to any changes in the indoor air.
Even the operation of this appliance is different from its rivals.
The appliance removes up to 99.95% of pollutants that are as small as 0.3 microns and is responsible for making your eyes water and sneezing, unlike its rivals that try to trap allergens and pollutants.
The Air Multiplier™ technology and 350° oscillation ensure that purified air isn’t concentrated to only a single corner of your room. Instead, the comprehensive overall filtration further contributes to its 99.95% cleansing rate.
Keep in mind that since this air purifier is also a fan, there aren’t any Clean Air Delivery Rate (CADR) and Air Changes per Hour (ACH) ratings. Still, it offers a maximum airflow of around 334 litres per second which enables it to cover a large room efficiently.
The appliance has a ‘Night Time’ mode too that will make the LCD screen dimmer and the air purifier quieter.
You can connect the Dyson Pure Cool Purifying Fan to Amazon Alexa as well as the Dyson Link app, allowing you to activate the machine as you deem fit – with your voice or a tap of your smartphone.
As one would expect from Dyson, the Pure Cool Purifying Fan is incredibly well designed. Available in two colour options, it looks at home in most rooms.
But, all this comes at a hefty price. You have to shell out nearly AU$800 to get your hands on this appliance, but if you can afford it, it’s worth the money.
The Arovec True HEPA Air Purifier can remove bad odours, pet dander, and tiny dust particles from your home to let you enjoy a better breathing space. This is the main reason why it’s perfect for households that have pets.
Its CADR is above 100, which indicates that the appliance is efficient and fast. Then, of course, is the UV-C technology. This uses ultraviolet light in the C spectrum that makes it useful for destroying harmful microorganisms present in the air.
However, it is the air purifier's three-stage filtration system that makes this a worthy purchase. It consists of three layers: pre-filter, HEPA filter, and activated carbon.
The pre-filter consists of high-density mesh cloths that can intercept large particles, whereas the HEPA filter can filter and remove pollen, fungus, dust, mould, and so on while avoiding secondary pollution.
The activated carbon filters can neutralise unpleasant household odours such as cooking smells, pet orders, and cigarette smoke. It's this union of UV-C light along with the HEPA filter and carbon filters that can improve the overall air quality effectively.
It also uses titanium dioxide to make the filter process more obvious. Not only does it help to reduce airborne microorganisms, but it can also filter carcinogens and eliminate around 99.9% of the allergens in general.
This air purifier is best suited for rooms up to 12 square meters, so think twice before installing it in a larger space. You also get a two-year warranty, which is great considering its price of AU$180.
Although the company claims that the Arovec True HEPA Air Purifier has a whisper-quiet operation with the noise level between 30 to 50 dB, many customers weren't so sure – some reviewers found the appliance to be noisy, especially on the higher settings.
Also, the air purifier has a larger footprint that makes it necessary for you to use a spacious room for placing the appliance. This might be a problem for people with limited space.
Coway Mighty AP-1512HH Air Purifier
A strong contender that can fight indoor air pollution effectively, the Coway Mighty AP-1512HH Air Purifier has four stages of filtration: prefilter, deodorisation filter, HEPA filter, and vital ion filter.
While the pre-filter captures the largest particles, the deodorisation filter or activated carbon filter neutralises gases, odour, smoke, and other air pollutants. The HEPA filter and the ionising function are responsible for catching nearly 99.97% of dirt particles and enhancing the appliance’s air freshening capability respectively.
Coway claims that the California Air Resources Board (CARB) has approved the ionising function as well. This means that it’s certified to release less than 0.050 parts per million of ozone, making it completely safe for everyone.
Like many of our top picks, the Coway Mighty AP-1512HH Air Purifier has a particle sensor technology that actively checks your room’s air quality – if it detects excessive indoor pollution, the air purifier will immediately get to work. Once the air quality has returned to the acceptable level, it‘ll shut off the fan, conserving energy.
This air purifier is best suited for rooms up to 33.5 square meters.
It’s easy to see why The Wirecutter lists the Coway Mighty AP-1512HH as its best air purifier. So why didn’t we give it the top honour for Australia consumers?
While the air purifier's affordability should’ve been a pro, a few customers have linked it with the lower quality construction. Some have even reported the air purifier shaking violently and – unbelievably – parts like its fan exploding.
The risk of inconsistent quality on a budget product is aways a huge gamble for us – we recommend sticking with brands such as Dyson. You get what you pay for!
Travel Pick: AirTamer Portable Air Purifier
The AirTamer Portable Air Purifier is the perfect fit for people that are looking for a travel-friendly option, though it's not a full air purifier.
There are no filters in this machine, and instead, it uses electrostatic purification technology to create a germ-free zone around your train seat or plane. AirTamer claims that it can give you up to three feet of clearance.
The appliance emits a cloud of negatively charged ions that attaches to airborne particles to keep them away from your personal space.
You need to remember that this air purifier won’t neutralise gases, odours, or VOCs. It only works for eliminating viruses, bacteria, dust, pollen, and other particles. For example, when your co-passenger on a flight has a cough and cold, the appliance could protect you from catching the flu (we'd be remiss to point out that this claim requires further scientific study – you should NOT skip good personal hygiene habits because you're using a device like this!).
The AirTamer Portable Air Purifier has a lanyard cord that can be worn around the neck. It's also discreet because of the small and compact design. If you don’t want to hang it around the neck, you can also clip it to your belt or clothing.
Designed to be travel-friendly, the Airtamer only needs two lithium cell batteries that can give it seven days of continuous power. The fact that it comes with a travel case makes storage easier as well.
It cannot compete with our high-performing and power-packed top picks above, in terms of air purification efficiency. Still, it's a good option for people who want to stay healthy when travelling.
Special Mention: Salin Plus Salt Therapy Device
Heads up: the Salin Plus Salt Therapy Device isn’t a regular air purifier, but considering that it has some excellent reviews from Australians, this might be another option worth exploring.
This appliance gives you the benefits of salt therapy, releasing tiny salt ions into the air. This is possible due to the microcrystalline filter that helps trap airborne pollutants. Simply put, the air blown out through the appliance’s filter contains tiny crystallised salt particles. As it isn’t a traditional air purifier, you won’t find a HEPA filter fitted in its device.
Why salt particles?
The Salin Plus design revolves around using the benefits of salt therapy, which Salin claims has the power to ward off anaerobic respiratory infections. The company also says that when combined with osmosis, it helps to draw mucus away from airways that helps people to breathe easily.
We’d like to point out that salt therapy (or halotherapy) has no scientific evidence backing its claims of improving asthma or other lung conditions, according to the Lung Foundation Australia. However, there is plenty of anecdotal evidence with several people vouching for its benefits, and the device has received hugely positive reviews.
The Salin Plus Salt Therapy Device is very quiet – it has a maximum noise level of 40 dB. Also, the purifier has a controllable fan speed that can cover a room of up to 28 square meters, making it excellent for a single bedroom.
You get one filter cartridge with every purchase that should ideally be changed within 4 to 6 months.
What works for us is the affordable price tag and the high rating given to it by Australians over the years. Available at a price of AU$199.95, you get a one year warranty along with a 60-day money-back guarantee.
What didn’t work for us was the recurring cost of replacing the cartridge every couple of months. A single cartridge costs around AU$55, which means you’ll have to spend about AU$110 extra every year at least.
Also, as this device lacks a HEPA filter, we can’t recommend it if you want clean air – this should not be your pick if you’re worried about dust or airborne irritants causing allergies.
Who Needs an Air Purifier and How Can It Help?
Air purifiers can have diverse functions and forms, but they essentially do the same thing – improve the air quality of your abode.
This creates a question of who could really benefit from this appliance?
People Suffering From an Allergy
Many people suffer from pollen and dust particle allergies, especially during the spring season. Not only can they cause breathing problems, but it can also lead to constant sneezing, running nose, itchy eyes and skin.
Air purifiers can remove pollen and particles keeping this in check. There can be different triggers of allergy and hay fever – but, air purifiers work fairly effectively to remove them.
A common breathing problem, asthma affects people in varying intensity.
The biggest advantage of an air purifier for an asthmatic is that the appliance can reduce the number of irritants in your living space. In fact, several asthma patients have reported that they sleep better when the appliance is active.
Owning pets certainly makes the atmosphere livelier, but it also causes an increase in pet hair and dander. Your dog might also constantly be alternating between indoors and outdoors that can spread contaminants.
As pets tend to pick up dust, pollen, and other potential irritants in their coats, having an air purifier can keep cycling the air quality, keeping it healthy and germ-free.
Households with Smokers and Young Children
If your household has smokers and non-smokers, we would highly recommend buying an air purifier as it can trap and cycle the contaminants.
This can be really helpful in reducing the overall impact of second-hand smoke. Plus, the appliance also eliminates the lingering smoky odours.
We cannot stress the importance of babies and young children especially living in an unpolluted environment which can protect their immune system and respiratory system.
What Contaminants Can an Air Purifier Filter?
We’ve mentioned how an air purifier can filter smoke, VOCs, dust mites, dust particles, bacteria, viruses, mould, and so on. To give you a better idea of these contaminants, we‘ve made a complete list below:
- Plant Spores
- Household Dust
- Pet Dander
- Tobacco Smoke
- Gas Molecules
- Gaseous chemicals
Not all filters and not all purifiers can filter all of these contaminants, but it’s good to be aware of what you’re looking to deal with specifically.
Decoding the Different Air Filter Technologies
As mentioned earlier in the article, there are five different types of filter technologies. Let’s discuss them a bit more extensively.
High-Efficiency Particulate Arresting or HEPA filters are the most effective when it comes to trapping allergens.
It’s believed that these filters can capture nearly 99.95% of microscopic allergens and pollutants – some as small as 0.1 microns. This is primarily why various clinical settings such as hospitals use these filters for effective air purification.
The main job of ozone filters is to target odours and other unpleasant smells. However, they do not eliminate allergens or chemical pollutants from the air.
Ionic filters can remove small pollutants, and are best suited for large spaces. They create an intense electrical field known as corona discharge that yields a positive or negative charge to airborne particles.
These charged particles are then drawn to special plates that are housed within the purifier, effectively extracting them out of the air.
In the case of carbon filters, the air passes through an activated charcoal screen that clears smoke, chemicals, gases, and odours. They can absorb chemicals commonly found in domestic cleaning products like disinfectants, window cleaners, and so on.
The best part about these filters is their porous nature that can trap contaminant molecules before releasing the air. These filters are often paired with HEPA filters as the former itself cannot confine allergens and bacteria.
These filters pass air in UV light that makes the present bacteria and microbes harmless. Keep in mind that these filters aren’t effective against allergens, smoke, chemical fumes, or odours.
What Does an Air Purifier’s CADR Rating Mean?
You‘ll find several air purifiers being labelled with a clean air delivery rate (CADR) number. This is a metric developed by the Association of Home Appliance Manufacturers (AHAM) to help you understand just how effective the device is at filtering different particles present in specific room size.
For example, a CADR of 150 for pollen means that the appliance can reduce the total pollen concentration at an equivalent of one 50 cubic feet of fresh air per minute.
Remember: the higher the CADR number, the higher the number of particles the air purifier can remove.
How Much Maintenance Would Your Air Purifier Require?
Air filters play a crucial role to determine the level of maintenance required for air purifier.
- HEPA Filters: Typically, these filters can last for about a year. Lately, though a few brands have started offering filters that can last up to 5 years.
- Carbon filters: Activated carbon filters generally last for 6 months.
- Pre-Filters: These can last for around 3 months. But, models with washable filters have a longer life.
The Bottom Line
We’ve tried our best to include the most effective air purifiers available on the Australian market. Out of them, our two top picks, Ausclimate Winix Ultimate 5 Stage AUS-9500 and the Dyson Pure Cool can not only remove allergens and bacteria from the air but are also high-quality and durable.
