Why use the Dust Filter?
 

 

The Dust Filter provides constant protection for your computer 24hrs a day. For such a small price it could save you many hundreds of dollars in repairs, data loss and downtime.

How does the dust get into my computer?
 

 

 

Dust enters the computer case as unfiltered air. Most computers have a CPU fan to keep the CPU at a working temperature and a power supply fan to exhaust heated air our of the case. This creates a negative air pressure within the case and cool unfiltered dust laden air is drawn in through air vents, drives and any other openings around the case and settles on the components.

What does dust do to my computer?
 

 

Dust traps heat on electronic components like an insulating blanket. Dust builds up on fans, heatsinks and other components trapping heat causing overheating and failure of components in your computer. Dust can also cause short circuits and can be a fire hazard.

How does the filter work?
 

 

By introducing a intake case fan and filter, this promotes filtered air to enter the computer case from just 1 intake (some computers may require 2 case fans) and eliminates the chance of unfiltered air being drawn in the case through the air vents etc.

The Dust Filter is a major breakthrough in helping eliminate the build-up of dust in the computer case. It is designed to be completely disposable, perhaps just like an oil filter in a car. Depending on the environment of the computer, it is recommented the Dust Filter and case fan be replaced between 6 - 12 months. To get the most benefit from the Dust Filter, used computers should be professionally cleaned before installation.  

The DUST FILTER will help prevent overheating and prolong the life of a computer.
