shares Dyson, the manufacturer’s of the iconic blade-less fan, declares war on the smallest of villains as they launch their new line of Pure Cool air purifiers in Singapore and Japan. Diesel exhaust fumes, tobacco, soot, heavy metals and toxic organic compounds, are all present in the air. 10,000 litres of this air passes through our nose, mouth and lungs every day. It is this particulate matter, invisible to the human eye that affects more people than any over pollutant. The smaller the particles, the more harmful they are to your health. Airborne particles can cause allergic response and irritation. Crucially, particles as small as PM0.1 can enter the bloodstream and circulate throughout the body, causing more serious long term and short term illness, such as respiratory infections, skin ageing, asthma, even heart attack and stroke. Air purifiers can help combat this. But existing purifiers are inefficient, forcing air through their filters, allowing harmful, ultrafine particles to escape back into the room. The Dyson Pure Cool is the only purifier to use Dyson’s patented 360° Glass HEPA filter. This technology captures 99.95% of particles as small as PM0.1 – trapping it in the filter, so it doesn’t enter your lungs. It projects clean, purified air around the room evenly and quietly. Helping you keep healthy. ￼￼Toby Saville, Dyson Microbiologist: “Dyson engineers focused on developing a high performance filter, capable of capturing the finest, potentially most dangerous particles. The 360° Glass HEPA ￼filter was iteratively tested with different particles to ensure maximum efficiency. The smoke from 228 cigarettes was fed through the machine – with no drop of filtration performance.” Conventional purifiers rely on big motors to force air through bulky filters to capture particles. However due to the velocity of the air, and the inefficiency of the filter, ultrafine particles can pass through, and back into the room. The filters often require changing, washing and drying on a daily basis, which can mean up to six hours without a purifier. 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, containing 1.1m2 of constructed microfibers. Unlike other purifiers that rely on non-woven filters, the Dyson Pure Cool’s filter has been pleated 254 times, meaning it can trap even the smallest particles – including pollen, bacteria, viruses and particles down to PM0.1. Clean air then leaves the amplifier loop at a high velocity and is directed over an airfoil-shaped ramp. This way, a long-range stream of smooth air is released, purifying the air you breathe. ￼￼￼￼ Dyson Pure Cool purifier fan is the only purifier that can also act as a fan, meaning the machine purifies and circulates all year round. Only after six months of continuous use will you need to replace the filter. And it takes less than 60 seconds to do so.
