Home cleanliness and healthy living has become more and more important to all of us over the years – yet even the most spick-and-span of houses can use a little extra help from time to time. For that reason, a lot of conscientious families are looking to air purifiers to help make sure they're breathing easy with clean, crisp air.

Yet as with any new home appliance, it can feel daunting at first to know which air purifier to choose – they range in shapes and sizes, there are brands both famous and less well-known making them, and they retail for all kinds of prices. How do you know what you're getting for your money?

Here's some help getting you up to speed on which air purifier is right for you – from the small-yet-powerful and budget friendly, to the mightiest mechanical marvels on the market!


What does an air purifier do?

It's not just the perks of a deep breath of fresh air that makes air purifiers the new must-have. After all, these devices are designed to remove things like germs, spores, dust particles and allergens such as pet dander or pollen from your room – the benefits of that are pretty appealing!

Air purifiers draw in the air from your room and process it through interior filters that are capable of removing incredibly small particles and objects from the air – far too small for people to ordinarily see.

This helps air purifiers offer extra health, protection and the overall energised feelings that come with a deep breath of fresh air. You might not have known it, but breathing in some of those particles – dust motes, pet dander, nasty germs and spores – could have been having an effect on your energy levels, sleeping patterns, and even your mood.

This is a step further than just fragrances for the home or scents to overcome stale air indoors. You're cleaning the air you and your family breathe at a deep level, which will have wonderful positive effects for you all over the long-term.

Maybe you need a HEPA-filter air purifier – that's High-Efficiency Particulate Air – that goes deep and thoroughly cleanses air through an incredibly fine mesh. Nothing gets past filtration that strict!

Think about who you live with too, or any pets you share your life with. People with asthma, or sensitive lungs or noses overall, will often appreciate more meticulously purified air than most.



Top picks – the best air purifiers on the market

There's lots to think about, but you don't need to fret. We've rounded up the best air purifiers around, to make sure you get a high quality air purifier that suits your budget. Take a look at our recommendations!

The PureMate XJ-1000 Silent Ionic Air Purifier

A small form factor and similarly small price doesn't mean missing out on a good budget air purifier. If you're keen to make sure you have a noiseless air purifier for a small to mid-sized room, this is a great choice.

The PureMate XJ-1000 is motorless, meaning it runs silently but also uses ionic technology to capture particles, spores, pet hair and other unpleasant dust – as well as absorbing cigarette smoke odours.

The interior dust plate collects all this unwanted stuff for you, so you can simply tip it out once you're ready. The ionic system moves air without the need of anything mechanical, so it's all very clever stuff – you can even hang it on the wall!

Purus Auto Air Purifier

The Purus Auto Air Purifier is suitable for rooms of up to 12 square metres in size. Standing 28 centimetres high, this is still a compact air purifier – but one with lots going on beneath its sleek-looking surface.

The Purus Auto Air Purifier uses HEPA technology, the same as leading premium brands like a Dyson air purifier, to ensure nasty odours, pet hair, particles, spores, germs and so much more nastiness gets removed from the air of your home.

In fact, 99.7% of these tiny pollutants get treated and purified with this machine, making it a portable-yet-powerful package when you're considering which air purifier best suits your home. Each HEPA filter in your Purus unit will last 12 months before it needs replacing – plus triple-layered filters overall help trap particles and fibres at different levels so nothing gets through.

Adjust settings on the fly while your Purus Auto is in use, and help you and your loved ones prevent illness and irritation from affecting your day.

The Dyson Pure Hot+Cool Advanced Air Purifier

When it's time for premium level protection that's both a smart home solution and a HEPA-filtered air purifier, the Dyson Pure Hot+Cool is the one to get. In fact, this Dyson air purifier is also a heater and electric fan all in the same space-age package!

Sleek appearance aside, this stunning piece of kit connects to a complementary Dyson smartphone app to help you gain real-time understanding of the gases, particles and temperature of your home. Naturally, you can adjust the device's response to this data with just a few taps and swipes of your thumb.

The cool circular LCD screen also gives you a handy readout of temperature, as much as air cleanliness and purity, as the machine sets to work. You can also set up timers to have your Dyson Hot+Cool activate and remain in action at regular intervals of your choosing.

As you'd expect of Dyson, the tech at work here is top notch. 350-degree oscillation keeps air circulated and temperature controlled around the entire room, and active sensors within the unit intelligently capture information on changes in the atmosphere.


Carbon filters, again with HEPA in action, capture up to 99.95% of particles in the air, while convenience features like the remote control, customisable air diffusion systems, quiet operation and optional nighttime setting for even quieter running makes the Dyson Pure Hot+Cool a sensationally indulgent and smart choice for your home.
