Dyson Purifier Hot+Cool HP12 De-NOx Air Purifier (White/Gold)

Advanced purification. Whole-room heating. Powerful cooling.

• Filtration: Automatically captures pollutants and gases, destroys formaldehyde², and adsorbs 50% more NO2.³
• Enhanced feature: Control and monitor air quality from anywhere using the MyDyson app.8

In 1978. James Dyson became frustrated with his vacuum cleaners diminishing performance. Taking it apart, he discovered that a bag was clogged with dust, causing suction to drop. He had recently built an industrial cyclone tower for his factory that separated paint particles from the air using centrifugal force. But could the same principle work in a vacuum cleaner?

He set to work. Five years and 5,127 prototypes later, he had invented the worlds first bagless vacuum cleaner.

Dyson’s latest purifier heats your whole room and cools you, with advanced air purification.¹ Automatically captures pollutants and gases, destroys formaldehyde², and adsorbs 50% more NO2.³

Key Features

Purifies, heats and cools you.

Advanced purification¹ and engineered for comfort. Delivers fast temperature relief.

Fully sealed to HEPA 13 standard

Removes 99.95% of particles as small as 0.1 microns.²

Captures 50% more NO2³

Our K-Carbon filter is impregnated with potassium carbonate (KCO) and can adsorb 50% more nitrogen dioxide - a common indoor pollutant, produced by gas appliances, open flames, and wood burning stoves.

Destroys Formaldehyde

Automatically detects and destroys formaldehyde, permanently.

Heats in winter

With long-range projection, it’s quick to heat the whole room evenly.

Cools you in summer

In warmer weather, a powerful stream of purified airflow can cool you down.

Senses and reports

Four sensors interact with a unique algorithm for precise air quality monitoring

Automatically detects airborne particles and gases, then diagnoses and reports them in real time.

Powerful air projection

Air Multiplier technology delivers over 290 litres per second of smooth, yet powerful airflow - 350° oscillation circulates purified air throughout the whole room.

Diffused mode

Diverts airflow through the back of the machine. To purify the room, without cooling or heating you.

Night mode

For lighter sleepers. Monitors and purifies using the quietest settings, along with a dimmed display.

Reports in real-time

LCD display reports in real time on PM 2.5, PM 10, HCHO, VOCs & NO2.

Oscillates up to 360°

Adjustable oscillation projects purified air around the whole room.

App and Voice control

Control and monitor air quality from anywhere using the MyDyson app. And control it hands-free with compatible voice services.

Easy filter care

The filter is quick and easy to change with automatic filter-life notifications on the LCD or Dyson Link app.

Remote

Curved and magnetised to store neatly on top of the machine.
