Today, the air movement experts at Dyson announced the release of the company's first air purifier: the Dyson Pure Cool. Essentially a combination of the company's existing Air Multiplier tech and the new 360-degree glass HEPA filter, the Pure Cool will launch in China and Japan this April, with a U.S. release coming at a later, as-yet-unannounced date.
Beginning with sales in Asia makes perfect sense. China's air pollution problems are well-known, and a 2010 Greenpeace study determined that it resulted in 1.2 million deaths in the country in 2010 alone. While this figure was largely down to outdoor pollution, indoor air quality is still important—particularly during the winter months.
There is some debate as to the effectiveness of air purifiers, and depending on the type, some can actually cause more harm than good. In particular, ionic air purifiers produce ozone as a byproduct, which can become harmful in enclosed environments. Still, air purifiers can be a boon for those suffering from severe allergies or asthma.
The Pure Cool will make use of a HEPA filtration system. HEPA stands for High Efficiency Particulate Air and was first developed as part of the Manhattan Project, as a means of protecting soldiers from radioactive particles. Known for their overall effectiveness, the only major downside of HEPA filters is that they do need to be replaced on a regular basis.
