Air Compressor vs Canned Air

[xNukam]

Okay so I found a $10 Air Compressor at Big Lots a little bit ago

But I'm wondering if this will be what I need to clean out the dust of my pc, I'm just tired of spending $5-$10 on canned air every few weeks, I just would like to know if this air compressor above will get the job done.

An air compressor is fine if the air coming out of it is filtered for both dirt and water. I highly doubt a $10 compressor has both of those.
