By going to greater lengths, we engineered a better filter.
The Dyson 360° Glass HEPA filter. Now with Tris-coated activated graphite.
The 360° Glass HEPA filter removes 99.95% of particles as small as 0.1 microns¹ – that's roughly 100 times smaller than a human hair. The 360° intake has been engineered to pull in polluted air from every angle, whilst the Tris-coated graphite captures gases from your home, including odours, household fumes and formaldehyde.
H-13 Glass HEPA borosilicate filter.
We've packed 6.3 metres of H-13 HEPA borosilicate microfibres into every Dyson filter. It's pleated precisely 333 times, to remove gases and 99.95% of allergens and pollutants as small as 0.1 microns.¹
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, odours and domestic fumes – in a similar way to how a sponge absorbs water.
After being treated with oxygen, each graphite crystal is coated with Tris. This organic compound's chemical reaction with potentially harmful gases like formaldehyde increases the graphite's ability to capture the gases, by as much as 70%.
Jet Focus control.
By harnessing the Coanda effect, Jet Focus control manipulates the flow of purified air precisely in a set direction. In focused mode, warm or cool air is powerfully accelerated from a rear aperture, and over a specially engineered focus ramp. In diffused mode, a jet of air is simultaneously released from an aperture at the front of the amplifier. The jets meet, and entrainment guides the air over a 45° projector.
