A simple air blower like the one pictured above costs just `500 but has several uses. The most common use is to blow the dust out from a desktop computer cabinet, but you can also use it to clean out set top boxes, TV cabinets, laptops, gaming consoles, projectors and various items around the house. If you plan on using the blower with an electronic item, make sure that you unplug the mains power first. It's also a good idea to take the device out in the open and use some sort of protection for your eyes, nose and mouth. You can buy an air blower from any computer market.
