Choosing The Right Duster
As you look at a duster can, whether on a store shelf or on your desktop, it is not likely that you'll recognize the difference between products. Of course, some cans are tall and some are short, but to the untrained user it is all the same.
Unfortunately, that is not the case!
In fact, these products feature a bit more complexity than one would think; and understanding that complexity will help you Make The Right Choice.
It is NOT Air in a Can
First and foremost, it is imperative to note that a computer cleaning duster is NOT "canned-air". This misperception, can lead consumers to use the product in a manner that can be harmful to themselves or to the equiptment they are cleaning.
Computer-cleaning dusters actually contain a liquefied gas, which functions as the products propellant (similar to any other aerosol product on the market). The only difference is in other aerosol products the propellant is used to propel a product (hair spray, cooking spray, insecticide, etc) through the nozzle. However, in a duster propellant is used to propel it's own vapors through the nozzle.
It is important to clarify this for two reasons:
- Understanding that these products are not just air in a can will hopefully give you a better appreciation for some of the information to follow, and help facilitate the need for proper usage, storage, etc.
- Most dusters today contain one of two types of compressed-gas, and understanding that there is a difference will help you select the right product for the job at hand.
