To maintain optimum cooling performance and stability of your computers and electronics it is necessary that on a regularly scheduled basis that you blow out the dust that accumulates. I have seen the interior components of computers so laden with dust that a blanket had actually developed causing the computer to overheat and stop functioning. Not forgetting to mention that dust build up on electronics can cause an overheated condition that potentially can lead to a fire.
A solution to this issue is to used cans of compressed air. This is a good solution; however, it can also be a costly solution with the costs of canned air being as high as $7 or 8$. A solution to eliminating the ongoing expense of canned air is the Metro Vaccuum Electric Duster. Bite the bullet on the cost of this duster and never buy cans of compressed air again.
Don’t let the name of this product fool you into thinking this is a vaccuum cleaner. It is the opposite, it is a duster with a 3/4 HP blower and it is awesome (and powerful) that will blow the dust out of just about anything. When blowing dust from your computer, make sure you do it in an open air environment (like outdoors) and make sure you wear eye protection.
I found a good deal on this at Amazon that you can use as a price comparison and where you can get a good read on the customer reviews (of over 1500 reviews). I cannot emphasize the importance of keeping your electronics dust free.
Electric duster is compact and comfortable to use.
