Product description
Product code: 86850909
Dyson Purifier Hot+Cool™ gen1 purifying fan heater. Automatically senses and captures pollutants to purify your whole room. Fully-sealed to HEPA standard – what goes inside, stays inside.
Whole-room purification
Only Dyson purifiers have Air Multiplier™ technology, to draw in distant pollutants and project 290 litres of purified air throughout the room.
Senses and reports, automatically
Sensors constantly analyse your air, while a unique algorithm cross-checks data per second. To precisely monitor, report and improve your air quality.
360 HEPA H13 filter
9 metres of borosilicate microfibres, pleated over 200 times capture 99.95% of pollutants as small as 0.1 microns.2
Activated Carbon filter
A layer of activated carbon captures gases such as benzene and NO2 emitted from cleaning products, candles and gas stoves.
The only purifier fully sealed to HEPA H13 standard
To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier4. So what goes inside, stays inside.
Heating your whole home can be costly and unnecessary
Dyson heater purifiers provide long range and whole room heating solutions in winter, so you don’t have to heat your whole home. Dyson heater purifiers have an intelligent thermostat, so it stops heating once the correct temperature is reached and energy isn’t wasted.
Heats in winter. Cools you in summer.
In winter, Air Multiplier™ technology projects purified, heated air throughout the room.4 Once your target temperature is reached, heating automatically stops. In warmer weather, Air Multiplier™ projects over 290 litres of air a second for cooling airflow.
Diffused mode. Purifies without cooling you.
Airflow is diverted through the back of the machine, maintaining effective purification.
Oscillates up to 350 ̊
Adjustable oscillation projects purified air around the whole room.
Night mode
For lighter sleepers, it monitors and purifies using the quietest settings along with a dimmed display.
