Focusing on our breathing is meant to calm us down. But if you’re worried about the air quality in your home, it can do the opposite. From dust mites and mould spores to odours from fires and cigarettes, there’s plenty of concerning reasons why the air in our homes might be less than fresh. Which is why we’ve been exploring the best air purifiers available today.
For people who suffer from asthma or allergies, the need for an air purifier might be particularly pressing. But pet owners are equally likely to want to get their hands on one of these nifty devices.
The best air purifiers use advanced filtration systems and a fan to filter out fine particles (that might otherwise end up in your lungs) before circulating clean air back around the space. They can eliminate pet dander as well as tiny allergen-causing particles, bacteria, viruses, and other nasties.
Reluctant to add a bulky piece of unattractive machinery to your home? Many of the best air purifiers are designed with an eye for aesthetics and are sleek and unobtrusive. Some even feature smart sensors to tell you exactly what the air quality is like in your home at any given moment.

Buyers guide: how to choose an air purifier
Choosing the right air purifier for your home will depend on your particular needs. How powerful do you need it to be? Which room do you plan to use it in? And how important are things like price or appearance? Here’s what you need to consider.
Type of filter
Air purifiers typically feature a pre-filter and a main filter. The pre-filters are usually fairly similar, although some are washable rather than disposable. The main filter is where air purifiers tend to differ.
- HEPA – this stands for High Efficiency Particulate Air. A HEPA filter is incredibly efficient and can filter out fine particles that cause allergies and asthma and also smoke (from cigarettes or wildfires) as well as pollen, spores, dust mites, and other pollutants. However, the cheaper models can be quite noisy.
- Carbon – activated carbon filters are particularly good at capturing odours, gases, and volatile organic compounds (chemicals in the form of gases), making them a great choice for those who smoke or have pets. However, they do need to be replaced regularly or can end up releasing all those captured pollutants back into the air.
- Ionic – this technology releases negative ions that attach to positively charged particles, making it easier for the filter to capture them. Air purifiers that rely solely on ionizing technology are the least expensive but also the least effective, leaving many impurities still in the air so you really want an ionizer combined with a HEPA filter. The other issue with ionizers is that they may produce ozone, which can irritate your lungs.
- Ultraviolet – air purifiers with ultraviolet technology inactivate airborne pathogens like mould, bacteria, or viruses (similar to a LARQ water bottle). However, like ionizers, there’s a danger that they may also release ozone. Plus, a UV-C air purifier isn’t that effective at trapping particles unless it’s paired with a carbon or HEPA filter.
Check the air purifier’s Clean Air Delivery Rate (CADR) to see how much air it processes and purifies in a certain period of time. The higher the number, the more particles it can remove.
Capacity also refers to the size of the room that the air purifier can accommodate, which can vary from 9 to 140 metres squared. Obviously, an air sanitizer designed for a small space won’t be able to turn over and purify as much air when placed in a larger room.
The efficiency of an air sanitizer refers to how well it filters out airborne pollutants. Most claim to be able to filter between 99 and 99.8%, although it’s worth remembering that these tests will have been carried out in highly controlled laboratory settings and the same results may not be possible in a domestic setting.
Nevertheless, you can expect most air purifiers to be able to filter out the vast majority of allergy and asthma-causing particles down to 0.3 microns in size.
Most air purifiers have different fan settings, with a quieter option or ‘sleep mode’, for use at bedtime. Some claim to be ‘whisper-quiet’, which means a noise rating of around 30dB.
Some air purifiers have been designed to be aesthetically pleasing with a low-key and understated profile and in muted tones such as grey and white. Other models are more functional than fashionable and look similar to heaters.
Air purifiers vary in price depending on performance and appearance. You’ll usually pay more for medical-grade filters or smart sensors. It’s possible to find air purifiers for under $100, while a high-end model could set you back around $600.
You may also want to look for a smart air purifier that uses sensors to monitor air quality and automatically adjust the fan speed accordingly. These air purifiers can also provide real-time feedback so you know what’s going on.
