An H14 filter and near-silent running. Best for ryegrass pollen and big rooms.
Coway Airmega 150
Low running costs and a stated H13 filter. One bedroom with the door shut.
Room sizes and prices for every unit are in the comparison table.
Which one for your part of Perth
- Hills and eastern suburbs (Kalamunda, Mundaring, Swan Valley, Armadale). Closest to bushfires and planned burns. Size for smoke, about five air changes an hour, and get carbon. For a big open-plan room, the Levoit Core 600S has the most lab-tested airflow we rate. Best for smoke.
- Central and coastal suburbs. The sea breeze usually clears the air by afternoon, but morning easterlies can bring Hills smoke in. A living-room unit plus a clean bedroom covers most days.
- Northern and southern growth corridors (Wanneroo, Baldivis, Peel). Newer homes are often open-plan, so check the size in the room calculator. One big unit or two smaller ones.
- Anywhere with wood heaters nearby. Smoke is worst on cold, still winter nights. Run a unit in the bedroom overnight. What you can do about a neighbour's heater.
When Perth needs one most
| Season | Problem | What to do |
|---|---|---|
| Dec to Feb | Bushfire smoke | Close up, evaporative cooler off, purifier on high |
| Autumn and spring | Planned burns | Check the burn-off schedule; run it overnight |
| Sep to Dec | Ryegrass pollen | Bedroom unit on auto, windows shut on windy days |
| Jun to Aug | Wood-heater smoke | Bedroom unit overnight |
This summer may be a heavy one. El Niño is tilting the odds towards a hotter, drier season.
Where to buy in Perth
- In store. Harvey Norman, The Good Guys and JB Hi-Fi have stores across Perth and stock most big brands. Useful if you want to hear how loud a unit is first.
- Online. Amazon, Appliances Online and the makers' own stores deliver to Perth. Allow extra days during a big fire, when stock runs short.
- Filters. Buy a spare when you buy the unit. Replacement filters sell out fast in smoke events, and some brands ship them from the east coast.
- Timing. Prices are usually lowest in winter. Fit a fresh filter each September, before burn-offs and pollen.

Indoors, yes, if it has a HEPA filter, is sized for the room and the house is shut. Turn the evaporative cooler off, because it pulls smoke inside.
