Thanks to the sheer volume of their usage, it is easy for computers to become dirty over time. It is important to ensure keyboards and mice (as well as components are kept clean) not just to prevent damage but also for hygiene reasons. A compressed air can is one of the most budget conscious and convenient ways to do so.
Compressed air cans project a high intensity blast of air (often a form of canned gas such as difluoroethane or trifluoroethane) which can easily blow away build ups of dust, which are the most common form of dirt in technology (with the possible exception of general spills), and can often be tricky to get at.
The ability to blast away the dust without actually having to access the areas is incredibly convenient, especially in terms of cleaning a computer's internal circuits: an area that can be easily damaged if those accessing them arenât careful.
Compressed air cans can be purchased for more than reasonable prices on the web. Many sellers will offer a multiple can deal, which can save on both the cost of the product and postage and is ideal for anyone working with computers in a professional environment, such as in an ICT or software department.
