About Wynd

Wynd Technologies, Inc. is based in Silicon Valley, California and was founded by MIT graduate Ray Wu.  As an avid traveler, Ray was concerned about air pollution and air quality issues, especially when visiting relatives in Beijing. Ray and the Wynd team wanted to create products that help people breathe healthier air wherever they go, so they launched Wynd.  

The first product, Wynd Plus, was launched in Kickstarter and generated over 12 times of initial crowdfunding target. It is one of the best air purifier sold through Kickstarter.  

In 2020, two new Wynd Products were introduced.  The Wynd Halo, a comprehensive air quality monitor which helps you track your indoor air environment.  The Wynd Max Purifier, which purifier the air of 600 square feet of space in 15 minutes, helps you clean your indoor air environment.
