Questions
Do purifiers help with bushfire smoke?
Indoors, yes, if it has a HEPA filter and carbon, suits the room and the house is shut. Turn the evaporative cooler off too.
What size do I need?
Go by realistic room size, not the box. Bedroom: Coway 150 or Levoit Vital 100S. Living room: Xiaomi 6 or Levoit 400S. Open-plan: Breville or Levoit 600S. The room calculator works it out exactly.
Does my evaporative cooler clean the air?
No. It pulls outside air in, smoke included, so turn it off on smoky days. Ducted reverse-cycle filters are for dust, not smoke.
How often do I change the filter?
Every 6 to 12 months, and sooner after heavy smoke. Fit a fresh one each September.
Is a dearer purifier better?
Not necessarily. The Xiaomi 6, at about $309, cleans more air than the Dyson HP09, which costs over $1,100.
Do ionisers help?
Not much, and they can make trace ozone. Most people leave them off.
