Cleaning for Allergies: Dust, Mites & Pollen

Allergies are common in Australia, and many people with hay fever, asthma or eczema find their symptoms are affected by what's in their home: dust mites in bedding, pollen tracked in on clothes, pet dander on the couch, and mould in the bathroom. Cleaning can't cure an allergy, but the right routine can reduce the allergens you live with every day. The wrong routine, such as dry dusting with a feather duster, can make things worse by throwing allergens back into the air. This guide covers practical cleaning for allergies: what to target, which tools help, how often to clean, and how to avoid stirring things up. It's general cleaning advice, not medical advice. If you have allergies or asthma, talk to your GP or an allergy specialist about your own triggers and treatment. The Australasian Society of Clinical Immunology and Allergy (ASCIA) also publishes reliable patient information on allergen minimisation.

Know Your Indoor Allergens

Dust mites

Dust mites are tiny creatures that live in bedding, mattresses, pillows, carpets and soft furnishings, feeding on skin flakes. They thrive in warm, humid conditions, which describes much of coastal Australia for a large part of the year. Their droppings are a common allergy trigger.

Pollen

Grass and tree pollen comes indoors on clothes, hair, pets and through open windows. In spring, hay fever sufferers often notice symptoms indoors as well as outside.

Pet dander

Tiny skin flakes, saliva and urine proteins from cats and dogs settle on floors, furniture and bedding, and can stay in a home long after a pet has gone.

Mould

Mould grows in damp areas such as bathrooms, laundries, around windows with condensation and in poorly ventilated rooms. Mould spores can trigger allergies and asthma.

Cockroach allergens

Cockroach droppings and body parts are also an allergy trigger. Keeping food areas clean reduces the food and shelter that attract them.

Tools That Make a Difference

A vacuum with a HEPA filter

A vacuum with a sealed system and a HEPA filter traps fine particles instead of blowing them back out of the exhaust. Empty bagless canisters outside, ideally with someone who doesn't have allergies doing the job, and change or clean filters as the manufacturer recommends.

Microfibre cloths, used damp

Damp microfibre cloths trap dust instead of moving it around. Avoid feather dusters and dry cloths.

Allergen-barrier covers

Covers for mattresses, pillows and doonas designed to block dust mites are often recommended for people with dust mite allergy. Ask your doctor whether they're worth trying in your situation.

A good-quality mask

If you have allergies and must do dusty jobs yourself, a well-fitting mask can reduce what you breathe in.

The Right Cleaning Order

Cleaning in the wrong order just moves allergens around. Work like this: 1. Open windows for ventilation, unless pollen counts are high on the day. 2. Dust from top to bottom, starting with ceiling fans, light fittings and high shelves, so dust falls to the floor. 3. Wipe surfaces with a damp cloth. 4. Vacuum last, including floors, rugs and upholstery. 5. Mop hard floors after vacuuming. If possible, the person with allergies should stay out of the room during cleaning and for a little while afterwards.

Bedroom: The Most Important Room

You spend about a third of your life in bed, so the bedroom is where reducing allergens usually matters most. • Wash bedding weekly in hot water. ASCIA's dust mite information includes guidance on washing temperatures and alternatives for items that can't be washed hot. • Use allergen-barrier covers on mattresses and pillows if recommended. • Reduce clutter, including soft toys, cushions and piles of clothes that collect dust. • Vacuum the mattress regularly. • Keep pets out of the bedroom if pet dander is a trigger. • Choose washable curtains or blinds that are easy to clean.

Floors and Soft Furnishings

• Vacuum carpets and rugs at least weekly, more often in homes with pets. • Have carpets professionally cleaned periodically. Make sure they dry fully afterwards, because damp carpet can encourage mould and mites. • Vacuum upholstered furniture, including under cushions. • Wash throws and cushion covers regularly. • Hard floors are easier to keep allergen-free than carpet, which is worth considering if you're renovating.

Reducing Pollen Indoors

• Keep windows closed on high pollen days, especially on windy days in spring. • Take off shoes at the door and use a doormat. • Change clothes and shower after spending time outdoors in pollen season. • Dry washing indoors or in a dryer during high pollen periods. • Wipe down pets after walks. • Check pollen forecasts, which are available for several Australian cities during the season.

Keeping Mould Under Control

• Run exhaust fans during and after showers and cooking. • Wipe condensation from windows and shower screens. • Fix leaks promptly. • Don't leave damp towels and washing lying around. • Clean mould as soon as you see it, and get professional help for large areas. Our guide to removing bathroom mould has a step-by-step method.

Living With Pets and Allergies

If someone in your household is allergic to pets but you have them anyway, a few habits help: • Groom pets regularly, outdoors if possible, by someone without allergies. • Wash pet bedding weekly. • Vacuum frequently with a HEPA vacuum. • Keep pets off beds and soft furniture. Our cleaning tips for pet owners cover pet hair and odours in more detail.

Heating, Cooling and Air Quality

Air conditioners, heaters and ducted systems can circulate dust if they're not maintained. Clean or replace filters as the manufacturer recommends, and consider having ducts and vents cleaned. Our guide to vent cleaning and indoor air quality explains what's involved. Portable air purifiers with HEPA filters can help in some rooms, but they're not a substitute for cleaning.

Choosing Products

Some people with asthma or sensitive skin react to strong fragrances or harsh fumes. Consider: • fragrance-free or low-fragrance products • avoiding aerosol sprays, which put fine droplets into the air • gloves to protect sensitive skin • good ventilation while cleaning.

When to Get Professional Help

If dusting and vacuuming set off your symptoms, handing the job to someone else can make life easier. A professional clean can include thorough vacuuming, damp dusting and bathroom mould control. Our carpet cleaning service can deep clean carpets, rugs and upholstery where dust mites and dander build up.

Frequently Asked Questions

How often should I clean if I have allergies?

Many people with dust mite or pet allergies vacuum and damp dust at least weekly and wash bedding weekly. Your doctor can advise on what matters most for your triggers.

Do HEPA vacuums help with allergies?

A sealed vacuum with a HEPA filter traps fine particles rather than blowing them back into the room, which can help reduce airborne dust during vacuuming.

Is carpet bad for allergies?

Carpet can hold dust mites and dander. Regular vacuuming with a HEPA vacuum and periodic professional cleaning help, and hard floors are easier to keep clean.

Should someone with allergies do the cleaning?

If possible, someone without allergies should do dusty jobs like vacuuming and emptying the vacuum. If you have to do it yourself, a mask and good ventilation can help.
