#1 Stay indoors
The best way to avoid breathing in bushfire smoke is stay inside with the windows and doors closed, preferably in an air-conditioned building.
#2 Set air conditioning on recycle
Avoid bringing smoky air into your house. If you have the option of adding a filter to your air conditioner, do so.
#3 Consider a portable air filter
It is recommended air cleaners with a HEPA filter to provide protection from particles. Devices that only humidify, generate negative ions, or absorb unpleasant smells do not reduce airborne particles.
#4 Avoid physical activity outside
It was a good idea to avoid exercising outside when you can see smoke in the air. If you run or do physical activity you breathe in a lot more because you need to get a lot more oxygen in, so your ventilation increases 10-fold and that means you are increasing your pollution exposure 10-fold.
#5 Keep medication on hand and follow a treatment plan
People with asthma — and other health conditions — need to make sure they have any medication they need on hand at all times.
#6 Wear a mask
NSW Health Department says wearing a P1 or P2 mask (available at hardware stores) properly fitted over your mouth and nose will filter fine particles and minimise the effects of bushfire smoke
#7 Leave the area
If the smoke continues for some weeks, or if a person's health means they're at higher risk because of smoke exposure, consider staying with friends or relatives outside the smoke-affected area.
