Busting dust in a basement shop

joints in ductwork. Wipe the duct
clean so the tape sticks, and smooth
the edges to the metal.

Foil dust's entry into ducts

A forced-air system that runs through your shop can send dust throughout the house, so check air ducts. Seal seams between metal duct sections with foil tape, photo right. If the cold-air returns consist of sheet metal nailed between floor joists, seal between the metal and wood with caulk, photo below right. Also, apply a bead of caulk along the top outside edges of the same joists where they meet the subfloor.

If the furnace itself lies within your shop space, wall it off to isolate it from dust. If possible, upgrade to a filter with a higher MERV rating to capture dust that gets into the ventilation system despite your best efforts. Water heaters or other appliances with pilot lights should also be walled off from your workshop.

.3 is fraction of one micron, thus, it is correctly stated/written .3 micron, not microns.

There are risks with using an air gun to remove dust from yourself, possibly blowing something into your skin, or worse into your eye, potentially with some force. Use a vacuum instead.
