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. This amplifies the initial airflow, projecting a powerful stream of smooth, uninterrupted, purified air.
Two sensors 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.
Common household pollutants
Common allergens - pet dander, pollen and dust
Bacteria and mold spores
Industrial emissions and smoke
Carpets, rugs and flooring
Household fumes and cooking
Benzene and VOCs
Cleaning products and candles
Gas stoves and car exhausts
Glass HEPA borosilicate filter.
We’ve packed over 20 feet of HEPA borosilicate microfibers into every Dyson filter. It’s pleated over 200 times, to remove allergens and pollutants.
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.
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.
