Buying an air purifier is only the first step towards improving indoor air quality. Where you position the unit has a significant impact on how effectively it cleans the air.
Here are the best locations for each room.
General Placement Tips
For best performance:
-
Leave at least 20–30cm clearance around the unit.
-
Avoid placing it behind furniture.
-
Keep air inlets and outlets unobstructed.
-
Position it close to common pollution sources where practical.
Bedroom
The bedroom is where many people spend around a third of their day.
The ideal position is:
-
1–2 metres from the bed
-
Away from curtains
-
Not directly against a wall
-
On a stable surface or floor
Running your purifier overnight can help reduce airborne allergens while you sleep.
Living Room
Living rooms often accumulate:
-
Dust
-
Pet hair
-
Fabric fibres
-
Outdoor pollutants entering through doors
Place the purifier in an open area where air can circulate freely.
Avoid corners where airflow becomes restricted.
Kitchen
Cooking produces:
-
Grease particles
-
Smoke
-
Odours
-
Fine particulate pollution
Position the purifier several feet away from the cooker to avoid grease clogging the filters while still allowing it to capture airborne particles.
Home Office
Working from home means spending many hours indoors.
Position the purifier close enough to circulate clean air around your workspace without directing airflow straight at you.
Children's Rooms
Place the purifier:
-
Away from cots
-
Away from play areas
-
Out of reach of small children
-
With clear airflow all around
Hallways
Hallways can help improve airflow between rooms, particularly in open-plan homes.
However, they shouldn't replace room-specific purification where pollution sources are concentrated.
Places to Avoid
Avoid placing your purifier:
-
Behind sofas
-
Behind curtains
-
Inside cupboards
-
Next to radiators
-
Directly beside open windows
-
Under shelves that block airflow
Final Thoughts
A well-positioned air purifier works more efficiently, cleans more air and helps maintain consistently better indoor air quality. Small adjustments to placement can make a noticeable difference to overall performance.
