Smart air purifier Airmega is your clean air police

LAS VEGAS — Here's a scary thought: The air we breathe indoors can be five times as polluted as outside air, according to the Environmental Protection Agency. Since most of us spend a considerable time indoors, we're inhaling a lot of what we shouldn't be.

Smart air purifiers, like those from Honeywell and Mi Air, sync up with apps. But a new air purifier called the Airmega, from Korean company and designed by Yves Behar, is taking air tracking a step further with built-in sensors that optimize the filtration process, based on what's happening to the air in your home.
