my take - shop air filter

I\'m old.
I like recycling.
I need an air filter to reduce the dust in my shop.
I found a box fan.
I often do a lot of sanding, which creates a lot of dust and covers everything.
I know there are store filters available commercially and I know it\'s not the most efficient way to do it, but it works and that\'s all I need.
It was built on projects published by many others and I appreciate them.
It\'s not demeaning their work, it\'s just to show how I did it.
It would be great if it helped someone.
As usual, safety always uses PPE around dangerous machines.
I made a simple sketch and wanted to know how it would go with it and what material I needed. 20\" Box Fan -
I found a wood of all kinds.
I put a few laminated floors on both sides, and the rest were removed from the store pile. Filter -
Cheap furnace filter.
I \'d be fine if I did.
If not, it would be easy to modify the framework to add filters and then consider becoming more expensive, but from what I read it seems to be the most economical.
After testing the fan, I washed it to remove dust and dirt.
The metal parts are then polished and primer.
I prepared all the wood rack parts and fixed them to each other on the fan.
Finally, I reconnected the front guard and inserted the filter.
I can put it on the floor next to where I polished it, or I can put my hands on a few ropes and hang it on the raf if needed.
Thanks for reading.
