Dyson and Asthma
Dyson upright and cylinder vacuums are approved by allergy associations worldwide, including the British Allergy Foundation (BAF). The BAF have also validated our asthma and allergy research, helping us develop even better technology for removing household allergens.
Why a Dyson vacuum is the most effective for asthma and allergy sufferers...
No loss of suction power
Every Dyson vacuum uses patented Root Cyclone™ technology. Unlike other vacuums, it doesn’t lose suction power so it removes more dust, dirt and allergens from your home.
Only clean expelled air
Some vacuum cleaners can’t keep hold of all the dust they pick up – so they vent it back into your room. That explains the dusty, electrical smell. Dyson cyclone technology is 99.9% efficient at separating dust and dirt. Dyson cyclones can capture particles down to 0.5 microns (approximately 200 times smaller in diameter than human hair) – including pollen, mould and bacteria.
HEPA filter
Dyson Allergy and Animal machines have a sealed HEPA (High-efficiency Particle Airflow) filter to capture particles as small as 0.1 microns. That’s equivalent to a single particle of cigarette smoke.
How Root Cyclone™ technology works
- Fibres and pet hair are separated out of the airflow and deposited in the bin
- Dirt is drawn into a powerful cyclone. Centrifugal forces of 500G fling larger dirt, debris, fibres and pet hair into the clear bin.
- Finally, a cluster of smaller, tighter cyclones generate centrifugal forces up to 150,000g, which extract particles as small as bacteria. You could fit 200 on this full-stop alone.
- Dyson cyclones can capture particles down to 0.5 microns – including pollen, mould and bacteria.
Dyson microbiology lab
Dyson has its own microbiology lab at its Research, Design and Development centre in Wiltshire.
In it, Dyson scientists study household dust and dirt, in all its forms. A lot of the work they do involves studying house dust mites (Dermatophagoides pteronyssinus). They keep them in colonies, feeding them a ground-up mixture of wheat germ and dog biscuit in ideal temperature conditions (25oC and 75% relative humidity). Their research informs new and better ways of removing them.
Dyson microbiologists were instrumental in the development of the Dyson Airblade™ hand dryer. Working with leading independent hygiene specialists they developed new criteria for measuring hand dryer hygiene. Part of it involved 50 raw chickens - put to good use to contaminate hands in order to measure hand bacteria before and after washing and drying using different types of hand dryer.
Dyson is thought to be the only appliance manufacturer in Europe (possibly the world) to have its own in-house microbiology lab.
