Engineering story

“Multifunctionality shouldn't mean compromise. Dyson technology works properly, without exception.”

James Dyson – Engineer

Dyson Pure Hot+Cool™ purifier fan heater in test lab surrounded by heat sensors

Why Dyson heaters are fast to heat the room evenly

Dyson robotic rig

Setting the bar higher for personal cooling

To understand effective cooling, Dyson engineers spent 5 months building a specialized robotic rig that moves through three planes of motion. Unlike other test methods, which only monitor airflow in one position, it automatically maps airflow velocity everywhere in the space.

How we pushed beyond industry test standards, to purify every corner of the room¹

Demonstration of how long the HEPA filter is

Improving our HEPA filter, pleat by pleat

We've increased our HEPA filter length to 29 feet – the length of two family cars. The more filter media, the more effective the filtration. So we pleated it over 200 times, to fit inside our machine.

Enough activated carbon to fill over 40 soccer pitches

A single gram of activated carbon has a surface area in excess of 1,000m2. So the 300g in our machine goes a long way. At 300,000m, it's enough to fill over 40 soccer pitches.

1,148 tests. Not one compromise.

We built thousands of prototypes, made numerous iterations, and ran hundreds of tests. But our goal never changed: to develop a multifunctional machine, without compromise.
