Product information

This Dyson Purifier Hot + Cool Auto React is a heater, a fan and an air purifier, all in one. Its clever Air Multiplier technology sends a stream of purified air around the whole room quickly and evenly, letting you breathe easier. The HEPA filter captures up to 99.95% of particles in the air and gets rid of nasty smells and germs. There are even built-in sensors that analyse the air around you and show you the results on the LCD screen, so you can see it working in real time. Better still, with a long-range projection it quickly cools you down in the summer and warms you up in the winter.

Good to know

- It's low maintenance - the filter is quick and easy to change, and you get a notification on the screen when it needs replacing
- On Night mode, it runs extra quietly with a dimmed display – even the lightest of sleepers won't be disturbed
- The remote control is magnetic and rests neatly on the top of the machine
- A draught-free diffused mode purifies the air without making the room colder
- It oscillates up to 350° for purified air in the whole room
