Dust Control

Sanding is an inherently dusty process—you’re removing a thin layer of wood with every pass. Good dust control clears dust particles from your work surface before they reach the air and your lungs. Most sanders include a bag or canister, but connecting the sander to a shop vacuum is more efficient for larger jobs. If a sander’s dust port is too narrow for your vacuum hose, you can use an inexpensive adapter to fit most profiles. I like to attach my sander to a shop vacuum with a HEPA filter or to a Festool dust extractor, which captures particles down to 0.3 microns.

Comfort

Comfort matters when you're sanding for hours. A lightweight orbital sander—about 2½ to 3 lbs.—is easier to maneuver and reduces fatigue, especially overhead or on vertical surfaces. Vibration control is just as important; too much vibration can numb your hands over time and reduce precision. Look for sanders with comfortable grips and well-balanced designs that absorb shock—they’ll let you work longer without strain. The right mix of low weight and minimal vibration makes long sanding sessions manageable and keeps your results smooth and consistent.
