Why a Dyson vacuum cleaner is the most effective for people with asthma and allergies

Most ordinary vacuum cleaners can’t retain all the dirt and dust they pick up – some is expelled out of the machine and back into the air. Dyson vacuums use Radix Cyclone™ technology and are more than 99.9% efficient at separating dust and dirt. Dyson barrel, upright and compact vacuum cleaner models with a HEPA filter remove particles as small as 0.1 microns. So the air expelled contains up to 150 times less mould and bacteria than the air you breathe.

3. Protective mesh
Expelled air contains up to 150 times less allergens than the air you breathe.

2. PTFE filter with HEPA performance
Air passes through a PTFE (polytetrafluoroethylene) filter, which is 99.97% efficient at removing particles as small as 0.3 microns.

1. Protective mesh
Allergen-laden air is drawn into the filter through a protective mesh.

Dyson and Asthma in New Zealand

In New Zealand, asthma is a potentially fatal condition that kills just over 200 New Zealanders every year. It is a condition that is widespread across all age groups, especially children of whom 1 in 4 are affected. Whilst at Dyson we know we cannot cure asthma, we do know that we can help reduce asthma triggers in the home and that's something we hope will make you breathe a little easier.

Asthma and Respiratory Foundation of New ZealandAsthma and Respiratory Foundation of New Zealand

Dyson is the only floorcare company to partner the Asthma and Respiratory Foundation of New Zealand. The main objective of this alliance is to help accomplish deep reaching, long term and better solutions for people with asthma, whilst raising funds and awareness for the foundations.

Asthma and Respiratory Foundation's Sensitive Choice programSensitive Choice

Dyson is also proud to be accepted as part of the Asthma and Respiratory Foundation's Sensitive Choice program. The Sensitive Choice program was developed to assist consumers to identify products that are low irritant and low allergy, and which may help reduce their symptoms.

Dust and allergies

Most common allergic reactions are triggered by dust mites and their faeces, pollen, fungus, fibres, food particles, pet hair and dander, and insecticides – all ingredients that make up household dust. Because a Dyson vacuum doesn’t lose suction, it removes more of these triggers from the home with every clean.

HEPA filter

Some Dyson barrel, upright and compact vacuum cleaners have a sealed HEPA (High-Efficiency Particle Air) filter - the same filters used by hospitals – to capture particles as small as 0.1 microns. That’s equivalent to a single particle of cigarette smoke. Particles this small include common household allergens such as pollen, mould spores and dust mite faeces.

Dyson microbiology lab

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

Here a team of 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 helps Dyson develop new and better ways of removing them from your home.
