Create your own, personal bubble of clean air and take it with you wherever you go. This personal air purifier removes dust, allergens, smoke, and pollution, and even helps you track when you might need to use it. You adjust the air quality manually to whatever feels comfortable—or leave it to the tracker to choose the appropriate level automatically. Wynd is small enough to keep at your desk or slip into your car’s cup holder. When it’s on, it delivers nine liters (a three-foot radius) of purified air. And its included tiny tracker changes colors and pushes notifications to your phone to warn you if the surrounding air is unhealthy. You can slide it into the bottom of the purifier or clip it on to a purse or backpack to use it independently when you’re on the go. Maker Ramond Wu wanted to create something that would not only help people breathe cleaner air, but would also help them understand when the air around them is unhealthy—which is often difficult to detect. People take around 20 thousand breaths every day. With Wynd, we can make sure more of those inhales are fresh and clean.
