How to make your own woodshop dust collection systems
Sanding wood produces sawdust that can irritate your nasal passages and lungs. (man sanding window frame image by Richard J Thompson from

Dust collectors systems collect dust and trap fumes. Tools such as table and mitre saws produce chips and sawdust, but sanders produce an especially fine sawdust that stays in the air and can irritate your nasal passages, sinuses and lungs. Vacuuming often can reduce residue in your workshop, but a dust collection system filters the air of sawdust particles and irritants.

  1. 1

    Put the general purpose air filter onto your worktable so the direction arrow points upward.

  2. 2

    Put the fine-particulate air filter on top of the general purpose filter so the direction arrow points upward.

  3. 3

    Measure and cut 20 inches of duct tape. Wrap it along one side of the stacked filters. Fold the extra tape over each side of the filter's edges. Do the same for the other three sides of the filter. Now wrap one continuous piece of duct tape around the taped areas to seal any gaps.

  4. 4

    Place the taped filters against the back of the box fan so that the fine-particulate filter is against the fan. Tape the filters to the fan so there are no gaps.

  5. 5

    Plug the fan in and set it on high. The fan should be facing the sander so it can pull airborne sawdust through the filters and keep the air in your workspace clean.
