Removing dust using a hand pump

Abstract

A method of cleaning dust from a computer, computer keyboard, mouse, monitor, or desktop using a hand pump capable of blowing air out of the pump or vacuuming air into the pump. A pump for carrying out this method is disclosed, which pump contains a cylinder having a proximal end and a distal end, a piston inside the cylinder, a handle operatively attached to the proximal end of the piston, and a nozzle at the distal end of the cylinder wherein the hand pump contains side valves adjacent the distal end of the cylinder, which valves open when the piston is moved distally and a front valve which opens when the piston is moved proximally and the cylinder has a dust container surrounding the side valves to collect the dust exiting the side valves to prevent the dust from blowing outside of the cylinder.
