Frequently asked questions

Can a Dyson purifier fan lower the room temperature?

Dyson purifier fans are engineered to provide powerful, personal cooling. They're not designed to lower the temperature of a whole room like air conditioning does.

Which Dyson air purifier should I choose?

All our purifies capture pollutants to improve air quality. The Dyson Purifier Cool Formaldehyde purifier fan also detects and destroys formaldehyde, while the Dyson Purifier Hot+Cool purifier fan heater heats in winter and cools you in summer.

How does a Dyson air purifier work?

Dyson purifiers capture gases and 99.95% of ultrafine particles from the air. Air Multiplier™ technology amplifies surrounding air, projecting a stream of powerful, smooth, high-velocity airflow. So they project purified, cleaner air throughout the room, or wherever you need it.

How loud are Dyson air purifiers?

Dyson air purifiers feature a Night mode. This mode uses the machine's quietest settings with dimmed display for lighter sleepers.
