Amid rising concerns by the World Health Organization (WHO) about the deteriorating quality of air around the world, Dyson has launched a new air purifier fan technology in Saudi Arabia that captures pollutants that could cause potentially threatening respiratory diseases like asthma. The World Health Organization (WHO) estimates that over 3.5 million people die each year from air pollution and about half of the urban population being monitored by WHO is exposed to air pollution that is at least two and a half times higher than recommended levels. Amid these staggering estimates, Dyson's revolutionary technology that removes 99.95% of potentially harmful ultrafine particles - as small as 0.1 microns from household air - could go a long way in helping reduce the impact of ambient air quality. In a country where the heat keeps people indoors during summers and air-conditioning is often used all year long, it is important to ensure that the quality of the air that people breathe indoors is pure. James Dyson says: "There is more to air than meets the eye. Dyson engineers focused on capturing ultrafine particles as small as 0.1 microns, and 450 prototypes later, we developed the Pure Cool purifier. Our unique 360° Glass HEPA filter is made of 1.1 square meters of constructed borosilicate microfibers, pleated 254 times; it means we can capture 99.95% of particles, as small as PM0.1." The ultrafine particles that the Dyson Pure Cool purifier captures are miniscule. But just how small is 0.1 microns? To put it in to context, a dust mite is around 100-300 microns, beach sand is over 100 microns, and particulate matter of size 0.1 microns (PM0.1) are roughly 100 times smaller than a human hair. These tiny particles are suspended in the atmosphere, and breathing them in results in them clinging to the lining of the lungs – which could lead to respiratory illness and other health problems. Air purifiers can help capture pollutants, bacteria, viruses, pollen, allergens and odours. But some existing purifiers are inefficient, forcing air through their filters too quickly and allowing these potentially harmful, ultrafine particles to escape back into the room. The Dyson Pure Cool purifier fan uses Dyson's 360° Glass HEPA filter. This technology captures 99.95% of particles as small as 0.1 microns – trapping them in the filter, and projecting cleaner, purified air around the room evenly and quietly. While several cities have been developing policies and strategies to combat rising levels of air pollution – technology can play a significant role in controlling the quality of air indoors. Using powerful Air Multiplier technology and an energy-efficient DC motor, the Dyson Pure Cool purifier fan draws in air via a mixed flow impeller. The air is passed through a patented 360° Glass HEPA filter, before cleaner air is passed through the amplifier loop at a high velocity and directed over an airfoil-shaped ramp. This way, a long-range stream of smooth air is released, purifying the air you breathe.
