Dust Protection Anet A8

Hello,
after 38 Days and 11:34 Hours printing and 11223m Filament i have a blogged nozzle.
The reason is dust. The cooling fan from the Extruder have blow dust on the Filament right before it is going in to the Hotend. Ok i have an Dust filter (see at the Things i made) but that dust filter is before the cooling fan.

After cleaning the nozzle, fan and the head sink i needed a solution for this problem.

Here is my solution.
easy, cheap and quick.
