Why is hard disk sealed?

The hard disk enclosure is sealed with a filter so that the disk can operate without impurities getting in the way. A single particle of smoke is several times larger than the distance between a disk and the read/write head. Anything that is even that small and certainly anything larger like a dust particle, would cause problems and probably disk failure.
