Air Purifying Drone / Air Purifying Drone

The Drone is a drone that can purify the polluted air.
The main object is providing clean air to people. Evidently, the atmosphere in cities is incalculable.
So, we do not aim to purify all of that enormous amounts. Instead, we focus on supplying clean air directly to the ground with
the drone's powerful motor. It will bring same effect as like operating a huge air circulator in cities.
The drone is designed as a double fan structure. The air filter is placed in each upside, and downside fan.
There are air filters between both fans purifying the fine dust through the inhaling and releasing process.
