Portable air purifiers and monitors

Why you need them and which to buy

It may be allergy season but you don’t have to suffer – there are many portable air purifiers and monitors that not only alert you to poor quality air, but clean it for you. Beacon (beacon-home. com) combines biorhythmic lighting and hi-fi speakers with an air quality monitor. You get real-time app updates on humidity, pollutants and more, plus advice on how to improve things. For a designer touch try Jacob Jensen’s Air Quality Monitor ( jacobjensendesign.com, right), which monitors indoor air and grades it. Want cleaner air in a jiffy? Pick up a Dyson Pure Cool Link (dyson. co.uk) and remove up to 99.95% of airborne nasties. Outside, use Wair’s Anti-Pollution Scarf (wair.fr/en) to filter out bacteria and pollen on the move.
