Automatically heats and cleans a whole room properly, capturing 99.95% of harmful pollutants as small as 0.1 microns.

To simultaneously purify and heat a whole room properly, the Dyson Pure Hot+Cool™ air purifer goes beyond standard tests by automatically sensing pollution, capturing ultrafine pollutants, and projecting purified and heated air using Air Multiplier™ technology.¹

¹The standard purification and heating performance tests are AHAM AC1-2015 and IEC 60675 respectively. Dyson goes beyond these, by testing filtration efficiency (EN1822), air projection (DTM801), purification coverage in a 81m³ room with multiple sensors (TM-003711) and heating performance in a 35m³ room with multiple sensors (DTM 961).

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.

Captures pollutants you can't see

The machine uses two separate filters. They work together to capture ultrafine particles and gases from the air you breathe.

Projects heated, purified air to every corner of the room

The machine projects over 290 litres of smooth, purified air per second. With 350˚ oscillation, it mixes and circulates the air to heat your whole room quickly and evenly.³
