Sidebar: A Rubber Hand Blower as an Alternative to Compressed Gas

An environment friendly alternative to using and buying cans of compressed gas to dislodge dust is a hand blower that relies on your squeezing to create an air stream to dislodge dust.

A hand blower is permanent whereas a can of compressed gas needs to be replaced every so often. However, it will require a little more time and effort since the air stream from a hand blower is not as strong as one from a can of compressed air.

I bought the one pictured here from Garrett Wade for $6.75, not including shipping.

This handblower even as a one-way valve at the nozzle tip to allow air to flow out only. Intake air is drawn through an orifice at the top of the bulb. In this way, the bulb is less likely to suck in the dust you are trying to dislodge in between squeezes.
