Dyson air purifier heater and cooler
Discover how a Dyson air purifier can make the air you breath cleaner. We take in up to 9000 litres of air in each day1. With more time spent indoors, it is vital that indoor air quality is treated properly. Our range of purifiers and Dyson air filters have been developed by Dyson engineers to trap microscopic pollutants and then project purified air throughout the room. Explore the range of air cleaner features to see which Dyson is right for you.

Dyson air purifiers feature a night time mode. This mode uses the machine's quietest settings. To ensure a comfortable night's sleep.
Dyson air purifiers and fans work differently to air conditioners. Rather than having cooling elements, using ambient air in the room, the purifying fan uses a powerful stream of airflow to cool you down. The cooling effect comes when the air, projected from the amplifier at velocity, passes over the user's skin. The higher the fan speed, the more powerful the airflow and cooler the air will feel.
