The air we breathe isn’t always super clean. It’s hard to know what’s in the air and how harmful it is to our health. Table Air is a portable air purifier that provides information about the contaminants we’re breathing. It hooks up via Wi-Fi to an app that produces data about pollutants. Table Air can be switched on or off to purify the air and the user can even adjust the air flow. One of these smart air purifiers will cost backers $95 with estimated delivery in November 2014. The Chinese Table Air hopes to raise $5,000 on Indiegogo.
