Is a Dyson air purifier able to lower the room temperature?

No, Dyson fans and purifiers are not designed to lower the room’s temperature and therefore is not an air conditioner unit. Rather, our products cool you by supporting the body’s natural cooling mechanism - by helping moisture evaporate from skin, which transfers heat from your body making you feel cooler.

Our devices provide you and your home with a powerful, targeted and pure cooling air flow.

How do Dyson fans work?

Our purifier fans use the Air Multiplier™ technology, which generates the circulation power to draw even distant pollutants into the machine, projecting purified air throughout the room.² And because they have no fast-spinning blades or grille, unlike conventional fans, they are safe and easy to clean.

How loud are the fans?

Thanks to the bladeless design our machines are engineered so that even the lighters sleepers can get a restful night of sleep. Which is crucial during hot summer nights as higher temperatures increase wakefulness, reduce deep wave and REM sleep. The Dyson Purifier Cool Autoreact is 20% quieter than the previous generation. So it can cool you, without disturbing your sleep. Additionally, with the sleep timer feature, you can programme it to turn off after preset intervals, from 15 minutes to 9 hours. 

Which Dyson fan is the best?

When it comes to choosing the best air purifier or fan for your needs and your home, there are some considerations to keep in mind that will help you decide. See our article here to find out more.
