Living in cities offers a plethora of opportunities, unfortunately some come at a cost to personal health, with pollution is at an all-time high with unbearable smog smothering the likes of New Delhi, Bejing, and Hong Kong. While some people choose to wear surgical masks to protect themselves, designer Jorge Alberto Treviño Blanco has developed a more stylish, practical alternative called Ohita.

A sleek looking octahedron, Ohita clips onto the wearer’s bag strap or can be attached to a wall. Functioning as a second set of lungs, it filters in bad air and breaths out clean air around the user. When exhaling, Ohita closes emitting air through a set of vents. When inhaling, Ohita exposes it’s bright blue luminous filter.

Ohita doesn’t just offer a purification system. Like Hand Tree, it is able to detect polluted air particles in it’s surrounding. Users may then upload the quality of air via smartphone to various social media platforms like Facebook and Twitter. On top of that, Ohita is also able to a capture smell and store a sample of it for a later time.

Ohita is still just a concept, having been named a semifinalist in Electrolux Design Lab competition, but as pollution continues to become a growing problem, devices like Ohita offer smart, well-designed ways to protect oneself.
