How to Build a Dust Collection System

Woodworking tools, particularly power sanders, can create a considerable amount of fine, airborne sawdust. This sawdust can be irritating to nasal passages and the respiratory system, and, in the case of some woods, the sawdust can even be toxic. Working in a well-ventilated area and wearing a dust mask can help, but one of the most effective ways to reduce the amount of airborne sawdust is to build a dust collection system that can be placed next to the work area to catch most of the airborne dust before it spreads.

20-inch-by-20-inch general purpose air conditioning filter
20-inch-by-20-inch allergy air conditioning filter
Duct tape

Instructions

- 1
  Place a 20-inch square box fan face down (with the power cord facing upwards) on a work table.
- 2
  Place a fine, allergy air conditioner filter over the back side of the fan. The air flow direction arrow on the side of the filter should be pointing toward the fan.
- 3
  Position a general purpose AC filter over the allergy filter on the back side of the fan. Once again, the filter's air flow direction arrow should be pointing toward the fan.
- 4
  Tape the two filters together around their perimeters, eliminating any gaps between the filters through which air could escape. Then tape the filters to the back side of the fan, eliminating any gaps through which air could escape.
- 5
  Stand the fan next to the work area, with the filter-covered side closest to the tool creating the sawdust. Plug in the fan, and turn it on high before beginning to sand. The sawdust created should be collected by the filters, helping to keep the air in the room clean.
