Dyson Hot+Cool™ Purifying Fan Heater

Dyson Purifier Hot+Cool™ Formaldehyde HP09 purifying fan heater. Captures dust, allergens and bacteria. Even destroys formaldehyde.1 Fully-sealed to HEPA standard – what goes inside, stays inside.

Powerful circulation to purify the whole room3

Only Dyson purifiers have Air Multiplier™ technology, to draw in distant pollutants and project purified air throughout the room.3

Senses and reports automatically

Four sensors, including a solid-state formaldehyde sensor, interact with our unique algorithm to precisely diagnose, display and react to your air quality.

Captures and destroys with advanced HEPA filtration

The HEPA+Carbon filter captures gases5 and 99.95% of particles as small as 0.1 microns.2 Our catalytic filter continuously destroys formaldehyde1. Captures dust, allergens and viruses8, including COVID-19 virus 9. Even destroys formaldehyde. 1

Destroys formaldehyde in billions of catalytic tunnels1

Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO2. And it self-regenerates, so it never needs replacing.

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.

1 Third party full machine testing based on GB/T 18801-2018 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.

2 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463)

3 In maximum setting. Tested for air projection, purification coverage in a 81m3 room.

4 Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.

5 Gas capture rates may vary.

8 Dyson purifiers were challenged with airborne influenza A (H1N1 virus) and MS2 bacteriophage at an independent lab, using a 30 m3 chamber. After 60 minutes at maximum fan speed, the airborne concentration in the chamber was reduced up to 99.9 %. Real-life efficacy may vary.

9 Dyson purifiers were challenged with airborne SARS-CoV-2 (the virus that causes COVID-19) at an independent lab, using a 0.37 m3 chamber for 90 seconds. Dyson Purifiers were also challenged with Phi-6 bacteriophage (a surrogate to test SARS-CoV-2) at an independent lab, using a 30 m3 chamber. After 90 minutes at maximum fan speed, the airborne concentration in the chamber was reduced by 99.9 %. Real-life efficacy may vary.
