The Change driving Air Pollution out of our Homes


The Dyson Pure range of air purifiers is built on decades of technology expertise and the cutting-edge design that Dyson is famous for.

Dyson engineers have spent years traveling the globe, testing the air quality in people’s homes and in doing so, they have detected the presence of pollutants, odours and gases, some innocuous and others which may be harmful to respiratory health.

With 25 years’ experience in air flow and filtration, from the research Dyson’s team of engineers and microbiologists carried out, they have discovered the air to contain, among other things, benzene, carbon and coal dust, dead skin and disintegrated faeces as well as formaldehyde.

They have spent years exploring a product that could purify the air, taking away some of the smallest particles floating around people’s homes which has resulted in the Dyson Pure Hot + Cool Link, a fan and heater which purifies the air all year round.

This product features air multiplication technology meaning when air flow is forced to change direction, for example by blades in a traditional fan, the disrupted air is turbulent and noisy. Dyson fans use air multiplier technology which doesn’t buffet the air and have been acoustically engineered to be quieter than conventional fans.

Some conventional purifiers concentrate on speed and force air through the filter which can allow allergens and pollutants to escape. This is a key frustration but it can be easily solved by sealing the filter into the machine. Using a rubber seal, the 360-degree filter is vacuum sealed into the machine’s body, meaning that all air drawn into the machine passes through the filter.

Other purifiers only focus on capturing particles down to 2.5 microns, but Dyson purifiers use a high-efficiency 360-degree glass HEPA filter. The filter media is pleated over 200 times, giving it a huge surface area, to capture 99.95 per cent of allergens and pollutants as small as 0.1 microns from the air. To put that in perspective, a strand of human hair is around 50 microns, so 0.1 microns is incredibly small.

This product also features intelligent sensing. Two sensors are located in the base of the machine, to constantly monitor the indoor air quality.

The first of the sensors detects particles larger than 0.1 microns such as pollen and allergens, whilst the second sniffs the air for Volatile Organic Compounds, detecting a wide range of gases such as fumes. All this data is sent straight to the Dyson Link app, making the invisible pollution visible and allowing us to monitor and keep on top of indoor air quality.

The sensors take the average dust and VOC readings over 45 seconds – rather than reacting immediately to every pollutant detected – to stop very short events starting the fan and constantly switching on and off.

There is also a Dyson link app which allows consumers to monitor the air quality within their home remotely. Simply download the app from the Apple Store or Google Play.
