Made this today to collect some dust out of the air in the shop. Made from some old scraps and an old roof vent fan. Uses 2-20X20 furnace filters.

This will be a lotta help from that nasty dust. I like the double filter idea

I’ll bet that thing really sucks! :-)

Good idea using the attic fan for this.

Do you use it on the floor or up on a bench or hanging from the ceiling ?

Definitely more heavy duty then mine. I just tie a filter, on the back side of a fan

Goat, Carl, Seems to work very well, I am very surprised at how much the first filter picks up. The first filter was basically plugged and I had to vacuum it out but the second filter was very clean. Dusty, I have used it on the floor set up on a saw horse, I am working on making it also hanging but want it versatile to do all three.

It would be best used off the floor to capture the fine particles in the “breathing zone” .
All of the bigger ,less harmful, stuff falls to the floor naturally and just clogs your filters faster : )

I made one like this, but a problem I have with it is that I can’t change the speed of the fan. As it is, it cavitates, meaning the fan speed attempts to pull to fast, almost as if there was no filter, just another wood side. If I start to slide the filter out, then it flows properly. Are you having that problem too?
