Managing indoor allergies means cutting allergens at the source and keeping the air itself cleaner, not just reacting when symptoms flare. Around one in three Australians now live with an allergic condition, according to the National Allergy Council, and a home is a busy source of triggers: dust mites in bedding, pet dander on the sofa, mould in damp corners and pollen carried in on clothes.
A plug-in ion unit like AeroPure's Ion Air Purifier works on the air between cleans, and a 60-day money-back guarantee lets you test it at home. If you have vacuumed, washed the sheets and still wake up blocked, the answer is usually a layered plan rather than one big fix. This guide builds that plan room by room, with links to the deeper guides on dust, mites, mould and sleep.
What causes indoor allergies in Australian homes?
Most indoor allergies trace back to four culprits: dust mites, pet dander, mould and pollen. Each one lives in a different part of the home, which is why a single fix rarely works.
Dust mites are microscopic creatures that feed on shed skin, and they thrive in warm, humid conditions, according to the National Asthma Council. The council adds that mould and dust mites thrive in the warm, humid environments found in many parts of Australia (NAC news).
Pet allergens come from fur, skin cells and saliva, and the NAC pets fact sheet notes they can stick to hair and skin and become airborne when a pet sheds. Mould likes bathrooms, fridges, built-in wardrobes and bedrooms with ensuites, per the mould fact sheet.
Pollen arrives from outside, on clothes, hair and open windows. Hay fever is the everyday name for the runny nose and itchy eyes that follow, and indoor triggers often pile on top of it in spring.
Where do allergens hide in your home?
Start in the bedroom. The National Asthma Council says the greatest exposure to dust mites is from your bed, so mattresses, pillows and quilts come first. Our dust mite bedroom guide turns that into a weekend routine, and our guide on whether an air purifier can improve sleep covers the air above the bed.
The living room comes next, where sofas, rugs and curtains hold dust that rises whenever someone sits down. Our guide on whether an air purifier removes dust explains what to expect there. Pet corners, such as the dog bed and the cat tree, shed dander into the room, and the Pet Odour Air Ioniser is made for those spots. AeroPure says it helps reduce airborne pet dander and odour particles.
Finally, check the damp places. A bedroom with an ensuite or a built-in wardrobe is a common mould spot, and our air purifier for mould guide has a three-step plan.
A weekly routine that cuts allergens at the source
Source control does the heavy lifting, and the National Asthma Council and ASCIA agree on the basics. Wash sheets and pillowcases weekly in water hotter than 60ยฐC, which kills mites and washes away their allergen, and hot tumble dry for 10 minutes after items are dry. Cover the mattress, pillows and quilt with dust mite resistant cases, and wash or remove soft toys.
Dust hard surfaces with a damp or electrostatic cloth, and vacuum carpets and soft furnishings weekly, with a HEPA-filter vacuum if you can. Vacuuming raises airborne dust mite allergen for up to 20 minutes, as Allergy Facts notes, so ask someone else to do it while you are out.
Keep the home dry and well ventilated, open the windows for 10 to 15 minutes a day, and avoid evaporative coolers and unflued gas heaters, which add moisture.
No single step is enough on its own, and the council says so plainly:
โfollowing just one measure is unlikely to make a differenceโ
That is exactly why the layers matter. Source control handles what has settled, ventilation flushes the stale air, and an air cleaner works on what is still floating.
What changes in spring?
Spring is when pollen and indoor triggers meet. Open windows bring in fresh air and pollen together, so the routine above matters more, not less. Keep the 10 to 15 minute ventilation habit, wash bedding weekly, and leave the unit running 24/7 so each room starts the night cleaner than it started the day.
It also helps to treat the bedroom as the base camp. If you only have the energy for one room this season, make it the room where you sleep, because that is where you spend the longest unbroken stretch breathing the same air.
A weekend plan for the whole home
Here is a simple split that fits a normal weekend. On Saturday, do the bedrooms: hot wash the bedding, fit covers and wash the soft toys. On Sunday, do the living areas and pet corners: damp-dust the surfaces, vacuum the rugs while you are out, and wash the pet bedding.
Every day, ventilate for 10 to 15 minutes and keep the units running. That rhythm takes about an hour of effort a week, and the unit does the rest between cleans.
Where does an air purifier for allergies fit?
It covers the third layer. The EPA describes air cleaning as a supplement to controlling pollution sources and ventilating (EPA guide), and the National Asthma Council includes it in its advice for people who live with pets:
โUse an air purifier to help filter out pet allergens from the air.โ
An ion air purifier gives airborne particles an electrical charge so they settle out of the air you breathe. The manufacturer says its unit helps reduce dust and dust mites that can affect indoor air quality, and the National Asthma Council notes that air filters and ionisers have been shown to reduce airborne mould.
There are no filters, fans or motors listed, the unit draws under 3 watts, and the maker says it produces no harmful ozone, chemicals or residues. As with any ioniser, you can ask for the test information, and our guide asks whether ion air purifiers are safe.
How do you choose and place a unit for allergy season?
Start with the bedroom and plug the unit into the outlet beside the bed, with clear space around it. One unit covers rooms up to 11 m2, so divide each room's area by 11 and round up. A 3 m x 3.5 m bedroom is 10.5 m2, which takes one unit, and a 4 m x 4 m main bedroom is 16 m2, which takes two.
Then add the living area and the rooms where pets sleep. The packs on the AeroPure Home page scale from there: the Bedroom Pack has 2 units and saves 25%, the Home Pack has 4 and saves 35%, and the Whole Home Pack has 6 and saves 45%.
For help with the counting, our air purifier for home guide works through three homes, and our small air purifier guide shows how little room a unit needs. The how to choose an air purifier guide covers noise, running costs and the trial, and our plug-in air purifier guide compares the specs.

Questions about indoor allergies
What is the best way to reduce dust mites at home?
Combine the weekly routine above with a unit beside the bed. Hot washes and covers deal with the mites, dry air slows them down, and the unit works on allergen in the air.
Do air purifiers help with pet allergies?
The National Asthma Council includes an air purifier in its advice for pet owners. This unit is designed to reduce airborne dust and pet dander, and the Pet Odour Air Ioniser is made for pet homes.
Is it safe around children and pets?
The manufacturer designs it to be safe around children and pets. As with any plug-in device, keep the unit and cord out of reach of small children.
How many units does a whole home need?
One for each room you use, sized by area. The full method is in our air purifier for home guide.
How long until I notice a difference?
The maker says many customers notice a fresher indoor environment within the first few days. You have 60 days from delivery to decide, with free tracked shipping and a one-email refund under the refund policy. More answers are on the FAQ page.
Layers beat any single fix
Clean at the source, ventilate every day, and give the air its own helper. That is the plan, and it works room by room, starting where you sleep. You can see everything in the full range, or read our guide to ion air purifier safety first if you want the full checklist.
