Hey guys
First project for the shop I thought to share with you. My shop is basically just a small portion of the basement so dust is always an issue. After seeing some nice ideas for air filters from fellow LJs, I decided to give the concept a tried. I bought a real cheap fan for 20$, and grabbed some 3/4 MDF left over from a friend’s project and here you go. The whole thing is quite large actually for my taste. It was more of an experiment than a real project at the start, so I decided to go with 3 filters (furnace filters, 0.99$ each); 1 at the entry, 2 at the exit. Turns out that 2 at the exit is overkill a bit and reduce the air flow. So picture 3 gives you how all this is made, and picture 2 shows the entry filter after an afternoon use. I wired it with a dimmer so I can turn the noise down a bit when working and put it in full speed when I leave the shop.
All comments are welcomed!

Nice build…I have made 3 of these for my shop and use 2 filters on the intake side so as not to get dust in the motor and shorten its life. They work really good..

Very nice build. I just replaced my furnace so this project is high on the list. Is it standard to have the air intake top and exhausting out the bottom?

Hi Jeff. Good question. Must designs that I have seen so far use a furnace fan, so the intake/outake are usually on bpth side. Since I had to go with a bottom/top design, I figured that I wanted the air flowing to the floor instead of hitting the ceilling and moving more dust into the air. But I don’t have any definite answer on this. Fortunately, I could just swap the fan upside down to change the direction of the flow if I want…
Ken; you should definitely try this. Just look at the picture of my filter, after 1 afternoon in the shop to realize that all this goes into your lung / everywhere in the house! :D I guess this design isn’t nearly as efficiant as the profersionnal one, but for 30$, it’s a no-brainer IMO.
