This is a simple homemade dust collector fan. I took out four fans from a couple small window fans that I was no longer using. I have them going though 3 furnace filters. The first one being a very cheap one that captures the heavy stuff. It does a reasonably good job.

Nice box you made for it. I think the filter on the exhaust side will only restrict the flow of air.
If you can find a used furnace (now called air handlers) squirrel cage type blower they work a lot better. Check local heating contractors for used ones.

Les – thank you for the advice. I wasn’t sure if I had wanted 3 filters on the inlet, or put one on the outlet. I have been using this for about 3-4 months now, and find that I am actually getting pretty good airflow through it, and finding that I am actually collecting a noticeable amount on the last filter. I have put in a central dust collector connected to my miter saw and table saw (and to be connected to other tools soon), so I have started collecting the majority of the dust at the source. This should greatly improve the overall air quality in the shop. I am sure over the years, I will improve on this collector.
