Improving indoor air quality

Having good airflow and using safe household products helps everyone stay healthier indoors. You can:

  • open windows and doors regularly to allow fresh air to circulate
  • use electric stoves instead of gas cook tops
  • use exhaust fans while cooking or showering
  • use electric heaters or a reverse cycle air-conditioners to heat your home – if you use a wood burning or gas heater, make sure it is flued to the outside and serviced regularly
  • regularly clean or change the filters in your heating and cooling systems
  • minimise the use of air fresheners and scented candles and avoid burning incense indoors
  • regularly clean dusty surfaces using microfibre cloths and mops
  • make sure clothes dryers are well vented so moisture does not build up
  • use chemical free cleaning products such as hot, soapy water or vinegar – or for stubborn stains, use a cream cleaner rather than a spray
  • always follow the instructions and open windows and doors when using chemical cleaners and sprays
  • choose furniture with low volatile compounds – check for certifications and opt for natural finishes such as natural oils or beeswax finishes over chemical intensive processes
  • consider using wooden/bamboo, concrete, or tiled flooring over carpet
  • avoid using glues, paint, or varnishes with high volatile organic compounds
  • avoid running vehicle engines in the garage
  • use an air purifier with a high efficiency particulate air (HEPA) filter suitable for the indoor space
  • use a door mat to help keep outdoor dust outside.
