We all know that all a typical fan does is move air around replete with a long list of sometimes deadly airborne contaminants. James Dyson said, “There must be a better way!”
Things like car exhaust fumes, tobacco, soot, heavy metals, toxic organic compounds, timber/plastic/compound furniture emissions, candles, gas cookers, cleaning sprays, house plants and pets, all release potentially harmful pollutants into your home.
To make matters worse the modern home is well sealed to contain heat or cold but in doing so, it leads to a static air and pollution build-up – often a toxic environment.
China’s Household Appliance Standard and Technology Industry Alliance has released the first global standard for intelligent air purifying fans – featuring test methods first developed on Dyson’s UK Technology Campus. By sensing pollution, capturing it and then circulating cleaner air, these machines are engineered to purify uniformly across a room.
Working in conjunction with Dyson engineers, experts at CHEARI have constructed a 27m2 test chamber designed to better reflect real average living room sizes of Chinese homes.
Tom Bennett, Head of Research, Design, Development and Operations for Dyson China said, “Globally, modern homes trap pollution and limit circulation, but for many people, it goes unrealised. We needed to create a smart machine that accurately senses the pollution for you and a sophisticated Dyson 360° HEPA purification system to remove it from the home.”
But it is not just about purification he added. “Through rigorous testing, we also discovered that to purify a room, powerful projection is key. With our Air Amplifier technology, we can deliver at least 200 litres of cleaner air every second to clean every corner, as our strong results under the new standard reveal”.
Lu Jianguo, Chief Test Engineer at CHEARI, said, “We are always looking at ways to accurately guide consumers toward technologies integrating high performance, smartness and uniformity of purification and recognise the growing need for intelligent air purifying fans.”
“Dyson leads the way in this category of purification so we’ve worked closely with their engineers to bring a test method to China that pushes the purification agenda forward, and welcome other manufacturers to enter into this new category,” he added.
About “air projection purifying devices.”
CHEARI’s new standard covers intelligent air projection purifying devices – a new category of purification. Machines meeting this definition must combine high-efficiency filtration of one or more pollutants (particulate matter, gaseous pollutants and microbes in the air) and air projection technology to deliver uniform purification around the room. The machines must also be intelligent, using sensors to automatically react to pollution and adjust the air supply rate based on the concentration of pollutants detected.
As a hay-fever sufferer I know first-hand how a toxic home environment can bring on itchy, watery eyes and start a sneezing attack that could rival an air-raid siren.
Over the past months I discovered that the microscopic ends of my home carpet pile were breaking off (time to replace the carpet) and how did I discover this? By the debris captured in a so-called air personal air purifier (not a Dyson).
Since replacing carpet with hardwood timber flooring, replacing all air-conditioning filters, and using a Samsung robot vacuum cleaner, my hay-fever attacks have miraculously subsided.
