DIY Dust Collector For Cleaner Workshop Air
A lot of dust can be generated in the workshop, especially with power tools. The dust is neither healthy nor pleasant to breathe. Effective air filtration in small workshops need not be expensive or complicated, here we show how to make a cheap effective versatile air filter for dust and particles from a box fan, furnace filter(s), and 3-D printed clips (or the handyman’s secret weapon: duct tape). For years in our wood shop we’ve used this 20″ box fan with a fine 20″ wide furnace filter taped over the back or inlet side of the fan. Having served us long and well she’s past retirement condition, so I worked in some upgrades while replacing it. I love duct tape as much as the next hacker or DIY’er (RIP Red Green), but I never liked its permanence in this application. The fan made a great air filter but no longer could easily be used to move more air for ventilation, so I designed and 3D printed some simple brackets that allow easy placement, removal, and exchange of different filters on two of our fans. At home I also use the more fiberous high flow air filters
