360˚ sealed filtration. Removes gases and pollutants.

The fully-sealed filtration system combines an activated carbon filter and a glass HEPA filter. They work together to lock in gases and pollutants, preventing dirty air from leaking back into the room.

Glass HEPA filter

Made with 29 feet of borosilicate microfibres, pleated over 200 times. It removes 99.97% of allergens and pollutants as small as 0.3 microns.

Activated carbon filter

Engineered using a dense layer of carbon crystals, and treated with oxygen to make it more porous. This increases the carbon's surface area, further helping to trap gases – such as formaldehyde, benzene and NO₂.

Continually monitors air quality, and reacts

The Dyson Pure Hot+Cool™ purifying fan + heater has three intelligent sensors to monitor what's in the air. Using a unique algorithm, it processes the input to provide real-time indoor air quality reports.

Fast, safe, efficient heating

Positive Temperature Coefficient plates

Self-regulating ceramic plates are positioned at the front of the amp, to heat the air as it leaves the machine. As the plates heat up, they conduct less electricity to help ensure they don’t overheat.

Thermostat control

Once your target temperature is reached, the machine automatically stops heating, which saves energy. If the temperature starts to drop, it reactivates to maintain it.

Demonstration of Air Multiplier™ technology

Powerful Air Multiplier™ technology

Air Multiplier™ technology delivers over 77 gallons of smooth, powerful airflow per second – circulating purified air throughout the whole room.²

Cutaway of Dyson purifier

Two airflow modes

The machine has two separate apertures, to release air from either the front or back of the machine. The valve mechanism turns a rotational baffle around the arc of the amplifier, to switch the direction of the airflow.

  • Forward projection

    Delivers a powerful stream of cooling, purified air from the front of the machine. 

  • Backwards airflow projection

    The machine diverts air through the rear annular at a 45˚ angle, creating a backwards airflow.
