How not to clean your computer of dust


Computers attract dust because they often do not have proper filters. Computers are seldom opened for cleaning because of the out of sight out of mind issue and dust can build up until the PC shuts down due to ESD (electro static discharge).

Dust is a big problem for computers in business, industry and home, and can significantly reduce the lifespan of the electronics. Using canned air is a risk to health according to this article at wikipedia, and when canned air is tilted it may release refrigerants. Aside from this canned air is generally not strong enough to effectively clean embedded dust in CPU sinks and the like.

Air compressors are too powerful for the delicate electronics boards of computers. Many types of air tools such as compressors create static electricity which weakens computer main boards.

The safest option for forced air with enough velocity to power clean embedded dust needs to be an ESD safe device.
