House dust mites and mould – two of Australia’s leading asthma and allergies triggers – thrive in humid conditions. A dry, well-ventilated home can help your family breathe easier.
Tips for climate control inside your home
- Make the most of natural ventilation and air circulation – open the windows!
- As well as ceiling insulation, don’t forget wall and floor insulation
- Replace any unflued gas heaters
- Make sure any wood fire heaters or open fireplaces have chimneys that are working properly so smoke doesn’t drift into the room
- If installing a new air conditioning, heating or ventilation system, consider choosing one that filters out pollens and other airborne allergens
- Let your bedding air in the sunshine – nice for you, not so nice for the dust mites
Many people who are sensitive to pollens can still throw open a window or air linen on the clothesline, if they choose the right time of day. Try to do this in the early morning when pollen levels tend to be lowest.
Mould and mildew
Living in a home that is damp or has visible mould, mildew or a musty smell can cause problems if you are allergic to mould or have asthma that is triggered by mould.
Mould is commonly found in bathrooms and fridges. It’s also found in places with little air circulation such as walk-in and built-in wardrobes, and in bedrooms with en suite bathrooms.
Ways to deal with mould
- Remove visible mould by cleaning with bleach or other mould reduction cleaners
- Seal any leaks in bathrooms and roofs
- Use extractor fans in the bathroom and kitchen
- Clear overflowing gutters and blocked underfloor vents
- Remove indoor pot plants (these can promote mould growth)
If you are very sensitive to mould or are troubled by bleach odours, you may need to wear a facemask while cleaning or have someone else do it for you.
