Anti-Haze Frame is an air system which is auto-powering and shaped in a window. The totally enclosed structure can effectively obstruct the air inside and outside.
When the air quality is generally good, the solar panels on the top can charge the storage battery and work as sunshade
When it is raining, the top plate can be used as a canopy.
When the air condition is poor, the top plate will filter the haze and convey the fresh air into the room.
