Pre-Filter Cover for Bosch Pro GAS 12V Vac by Bifiman

Last crawled date: 3 years, 1 month ago

This is a self-made cover for the paper-filter of the Bosch Professional 12V (== 10.8V) accu vacuum cleaner.
It protects the original filter against damage from little stones etc.
As there is some space left between the top of the paper filter and the top mesh of this cover, you can also add some filter fibre to build a prefilter. This way, the fine and hard to clean lamellas of the original Bosch filter don't fill up with dirt and dust so fast.
Until now, I followed a quite known hint from the internet to build a prefilter by modding some Dirt Devil filter, but now I created this part, which (as opposed to the Dirt Devil based solution) fits just perfectly onto the Bosch filter
Still have some ideas for a version 2.0, but this version already fits and works very well. if you also have some ideas, just add a comment. I may consider it for a future release.
