No matter where you live and work, you’re breathing in chemicals and pollutants, some more dangerous than others. And while changing that norm will take years, if not decades, of policy work, there are interim solutions. Among them: Wynd, a portable air ­filter—­roughly the size of a water ­bottle—that creates a clean-­climate bubble by sucking up pollutants in your immediate vicinity, including ones that can contribute to cancer and heart disease. “What we breathe matters,” says Ray Wu, creator of Wynd, which raised more than $600,000 on Kickstarter and ships April 2017. “We want to enable everyone to enjoy a healthy air environment, no matter where they live or travel.”
