Technology
By going to greater lengths, we engineered a better filter.

Air Multiplier™ technology.
The impeller draws in air from all angles, passing it through the filter before accelerating it into the annular loop. With technologies found in turbochargers and jet engines, and using applied fluid dynamics, air is induced and entrained – amplifying the initial airflow. In heating mode, self-regulating ceramic plates heat the air, before a powerful stream of smooth, uninterrupted, purified airflow is projected.

The Dyson 360° Glass HEPA filter with Tris-coated activated graphite.
The 360° Glass HEPA filter removes 99.97% of particles as small as 0.3 microns – that’s roughly 100 times smaller than a human hair. The 360° intake has been engineered to pull in polluted air from every angle, while the Tris-coated graphite captures gases from your home, including odors, household fumes and formaldehyde.
Two sensors to analyze indoor air quality. The dust sensor detects particles larger than one micron, such as pollen and allergens – while the Volatile Organic Compounds sensor identifies gases such as fumes and toxins.

Glass HEPA borosilicate filter.
We’ve packed 20ft of HEPA borosilicate microfibers into every Dyson filter. It’s pleated precisely 333 times.

Active Graphite filter.
The filter has been 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, odors and domestic fumes – in a similar way to how a sponge absorbs water.

Tris-coated.
After being treated with oxygen, each graphite crystal is Tris-coated. This organic compound’s chemical reaction with potentially harmful gases like formaldehyde increases the graphite’s ability to capture the gases.
