Engineering story

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

James Dyson – Engineer

Setting the bar higher for personal cooling

To understand effective cooling, Dyson engineers spent 5 months building a specialised 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.

Improving our HEPA filter, pleat by pleat

We've increased our HEPA filter length to 9 metres – 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 football 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 football 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.
