Air purifier vs fan: which problem are you solving?

01

A purifier and a fan do different jobs

An air purifier moves room air through filter media to reduce certain airborne particles. A fan creates airflow that can make people feel more comfortable. Neither function automatically replaces air conditioning or source control.

02

Choose a purifier for an air quality goal

Compare particle clean air delivery rate, room size assumptions, noise and replacement filter availability. Activated carbon can help with some gases and odours, but performance depends on the amount and type of carbon.

• Match CADR to room volume
• Check filter cost and local stock
• Compare sleep mode noise

03

Choose a fan for airflow comfort

Blade size, air speed, throw, oscillation and noise affect how a fan feels in the room. A fan can improve perceived comfort through air movement but does not remove heat from a closed room.

04

Combination products involve tradeoffs

A purifier fan can save floor space and simplify controls, but compare its filtration rate and airflow performance separately. A premium combined product is not automatically better at each task than two dedicated devices.

05

Reduce the source when possible

Ventilation, moisture control, kitchen extraction and avoiding indoor smoke can be more important than filtration alone. During outdoor smoke events, follow health authority guidance and manage doors and windows appropriately.
