Shop Fan/Air Filter

I decided to try to improve my shop air quality (on a budget), and I fully admit to spending way too much time on this, but I was having fun!

Case and stand are made from scraps of plywood, pine and 2 X 4, with some Masonite for accent pieces. Fan parts came from a box fan I had laying around. Knobs were made on my router pantograph.

I intended to put an electronic timer like I used on my drill cabinet, but I was feeling cheap, so I decided to use a mechanical timer that I already had.

Thanks for looking.

That looks like a 5 micron filter, cant get too much more than that and besides, filtering is a good thing

nice build, what impresses me the most is your little wood knobs! (for the rotation)

That’s a great idea, Chris. Nice project. I have a fan that looks exactly like that one and I am constantly moving it around to find a flat spot to set it on for cooling in the shop. Thanks for the idea!!!!!!!!!!!!

Cheers, Jim

Cool idea! Sorry, had to say that.
Nice work.

Nicely done Chris! I like the idea that you can tilt it and that it’s at work bench height so you can bring it closer to your dust maker.

Nice design. How did the filter affect the airflow?

Thanks everybody!

Woodnsawdust – the airflow is definitely reduced considerably with the 5 micron filter… Much better airflow with a cheap filter, so I’ll need to experiment as to which is more effective – better filtration with less airflow or better air flow with less filtration!

Very useful item. I too like the height and its ability to tilt. Certainly nicer looking and more functional than duck taping a filter onto a box fan. Not saying I do that. :)

I really like the tilting aspect. Great job.

As for the filtration, I would go for more filtration over air flow. If you get more airflow, all you’re doing is spreading the finer particles around more to where you’ll be breathing them.

Now that you’ve made one of these, you could easily make a couple others faster now and could place them strategically around your shop to have some nice circulation going.

This is a great idea—may have to add to my “to-do” list!

Question, though: Is 5 microns enough filtration? If I’m remembering right, we’re supposed to be shooting for 1 micron?

I like your idea of removing the grate on the back of the fan. I will incorporate that into mine next time I take it apart.

No. 0.5micron is even better. Otherwise, they just become dust generators recirculating the really hazardous, fine particles.
