Why a Dyson vacuum is proven effective for asthma and allergy sufferers

Some ordinary vacuums can’t retain all the dust they pick up – so they vent some of it back into your room. That’s the reason for the dusty, electrical smell. Dyson vacuums use Root Cyclone™ technology, which is 99.9% efficient at separating dust and dirt. All Dyson full-size vacuums also include a HEPA filter to remove particles as small as 0.1 microns. The air they expel contains up to 150 times less mold and bacteria than the air you breathe.

Dyson upright vacuums meet or exceed standards for effectively removing allergen-containing dust from carpets and are the first to be certified Asthma & Allergy Friendly™.

Clean air passes through a second protective mesh. Expelled air contains up to 150 times less mold and bacteria than the air you breathe.

Air passes through a porous filter made from polytetrafluoroethylene, which is 99.97% efficient at removing particles as small as 0.3 microns.

Air containing microscopic allergens is drawn into the filter through a protective mesh.

Asthma & Allergy Friendly™Asthma & Allergy Friendly™

Dyson upright and canister vacuums are approved by 12 allergy associations worldwide, including the British Allergy Foundation (BAF). The BAF have also validated Dyson’s asthma and allergy research, helping us develop even better technology for removing household allergens.

Dust and allergies

Most common allergic reactions are triggered by dust mites and their feces, pollen, fungus, fibers, food particles, even insecticides – all ingredients that make up household dust. Because they use Root Cyclone™ technology, Dyson machines don’t lose suction power, helping them remove more dust, dirt and allergens from your home. You won’t find Root Cyclone™ technology in any other vacuum.

Dyson microbiology lab

Dyson has its own microbiology lab at its Research, Design and Development center in Malmebsury, Wiltshire in the United Kingdom.

Dyson scientists study household dust and dirt, in all its forms. A lot of the work they do involves house dust mites (Dermatophagoides pteronyssinus), one of the most common triggers of asthma and allergies. They keep them in colonies, feeding them a ground-up mixture of wheat germ and dog biscuit in ideal temperature conditions (25°C and 75% relative humidity). The research conducted in our lab informs new and better ways of removing them.

Dyson is thought to be the only appliance manufacturer in Europe (possibly the world) to have its own in-house microbiology lab.
