Your Air Purifier FAQs
Give Your Home a Breath of Fresh Air with an Air Purifier!
What does an air purifier do?
We’re quick to clean benchtops and floors, but what about the air we’re breathing every day? Air purifiers work by drawing in air from the room and passing it through a filtration system that traps all sorts of airborne allergens, odours, and pollutants – from fine dust and pollen to pet hair, smoke, mould spores, and bacteria.
Whether you’re managing hay fever in spring or trying to prevent mould growth in stuffy, poorly ventilated rooms, an air purifier is the answer to cleaner, healthier air in your home or at work. A star performer in sleep zones and shared spaces alike, they work quietly in the background to freshen things up, one breath at a time.

Do air purifiers really make a difference?
In many Australian homes, indoor air can carry more than you can see (or smell). From daily dust to lingering odours, air purifiers filter out these particles to improve indoor air quality for a cleaner, healthier home.
With features like these, it’s no wonder they’re such a breath of fresh air:
- Freshness Fix – Clears stale air and odours from pets, cooking, and smoke, helping refresh bedrooms, living areas, and workspaces.
- Allergy Ally – Supports easier breathing by filtering out common household allergens that can trigger asthma, allergies, and hay fever.
- Pollutant Patrol – Filters out fine airborne particles and tiny droplets to help ease any sneezing and sniffles.
- Real-Time Readings – Built-in sensors monitor pollutants and display the quality of the air, so you’re always in the know.
- Always-On Comfort – Designed for continuous use with whisper-quiet operation and energy-efficient performance.
What should I consider when buying an air purifier?
What’s in the air can change with the seasons, the room, or who’s in it. From airborne pollen to nearby road pollution and four-legged family members that shed their fur everywhere, choosing the right home air purifier comes down to what’s building up – and where.
Have allergy or asthma troubles? Air purifiers with a High Efficiency Particulate Air (HEPA) filter are the go-to, trapping the microscopic particles like dust, pollen, and bacteria more effectively than the average model.
If it’s going in a bedroom or office, look out for quiet or sleep modes. These can be softer than a whisper, which makes a big difference when it’s running around the clock.
Where is the best place to put an air purifier in your home?
Air purifiers work best in the spaces you spend the most time in, like bedrooms, living rooms, home offices, or even at work. But for it to do its job effectively, it’s all about location, location, location!
For maximum impact, try these placement tips:
- Make Room – Keep away from walls, corners, and furniture. A bit of breathing space helps it circulate air more effectively – and help you breathe easier, too.
- Sniff Out the Source – Set it up in high-traffic areas with more dust, dander, or odours, like entryways or your pet’s favourite spot to nap.
- Double Up – Use a mix of large and small air purifiers across your home to cover more ground and keep every room feeling fresh as a daisy.
Remember to replace the air purifier filters regularly, keep it running (most modern models are energy efficient), and close windows and doors to prevent introducing any additional external pollutants.
