Laptop filters

provide dust & dirt protection for your PC. A common concern is that adding a Laptop filter to the air inlet port near the power supply fan may do little to block dust & dirt from entering the Laptop unit. Modern computers have numerous internal fans & it is often difficult to differentiate between the air intake & exhaust. Some fans are used just to circulate internal air. A simple Laptop filter on the back of a PC is not going to work for the long term.

A better computer filter solution is a breathable filter bag that covers all inlet & outlet ports of a Laptop unit but still allows the Laptop to be cooled properly. Modern dust bag style Laptop filters protect the entire unit from dust, dirt, & other airborne contaminants. They are designed in sizes to fit virtually any Laptop tower

& can be installed in minutes. They work well for monitors & printers as well, both of which need clean filtered air to assure proper long-term operation.

Laptop filters used on Laptop cabinets also do a poor job protecting your Laptop from dust & dirt in the long term. One reason is because majority Laptop cabinets require you to open the cabinet to operate the Laptop, for instance to access the CDROM or floppy drive. These operational requirements allow dust to bypass the cabinet dust filter & traps dust within the cabinet which eventually will be pulled inside the PC & settle there. This is completely preventable with a dust bag filter.

It is very important to use Laptop filters with PCs used in industrial or workshop situations where dust and dirt can very rapidly reduce the reliability and lifespan of the computer. Critical Laptop components exposed to dust and dirt, particularly the mechanical components like the keyboard & CD-ROM, can cease to operate without warning, & many times cannot be repaired once damaged by these contaminants. Studies have shown that dust can fill an unprotected Laptop in a matter of days, causing it to overheat. & metal dust can cause circuits to short-out, introducing a new workshop hazard. Dust bag style Laptop filters can do a lot to minimize these issues.

A problem with traditional Laptop filters is that they are designed to capture dust without impacting the amount of air that can enter the Laptop for cooling. This requires them to be fairly porous with the filter designed to capture the larger dust particles and allowing smaller dust particles and other airborne particles to pass through. The small surface area of the standard filter means that the air-flow must be relatively high, and dust & dirt collecting in the filter material quickly begins to restrict air flow. This problem is ameliorated by the larger dust bag, where the huge surface area of the filter translates into lower air-flow speed & a larger area to spread the dust trying to enter the Laptop. The lower air-flow speed also ensures less dust makes it through the filter material, especially smaller dust particles & airborne mists.

A small investment in a dust filter can provide a level of insurance that your Laptop equipment will operate when you need it to, & not wear out before its time. Dust bag style Laptop filters are especially effective, easy to install & inexpensive.
