Sure. You could use a $10 canister of "compressed air" to clean out your PC. But (a) it's not air, (b) just to repeat, it's not air, it's di/tetra-fluoroethane, (c) you're causing all kinds of thermal nonsense, and of course the most obvious (d): *it's one time use*.

Why are you using the fossil fuel equivalent of "blowing on things", have you considered just using electricity?
