Cleaning Your Computer and Dust Filters

Dust buildup inside your computer case is one of the main reasons it gets sluggish, or the components fail, as dust prevents proper cooling. Proper cleaning is very important.

If you’re considering using computer dust filters, you should clean the computer first to get rid of any dust build-up already within the computer. Magnetic dust filters are designed to stop dust getting inside your computer case, so it can operate like brand new. Preventing dust entering the case will not only optimize your computer’s performance (or that of any other electronic device), but also maximize its life span. 

Cleaning Your Computer

If you have a service contract that covers maintenance, consult with your provider to have your computer professionally cleaned. Otherwise, follow these steps.

  1. Check your owner's manual. If the manufacturer has provided specific instructions, follow them.
  2. Get any supplies you might need: a can of compressed air, Endust for Electronics or any household plastic or metal cleaning fluid, a soft brush (such as a paintbrush) and an anti-static rag, plus a dust mask if you're allergic to dust.
  3. Shut down the computer.
  4. Leave the computer plugged into the surge suppressor but have the power off
  5. Disconnect all peripherals from the computer.
  6. Remove the computer cover (see your owner's manual for instructions).
  7. Ground yourself to the computer with any professional grounding equipment you have. Otherwise, ground yourself by touching a metal part of the chassis.
  8. Spray compressed air over the fan blades, power supply chassis, drive chassis and circuit boards. Be sure to stop the fan blades from spinning while blowing compressed air over it. This can be done with a toothpick. Blow as much dust out of the PSU as possible. Do not open unless you are familiar with the dangers and precautions needed.
  9. Gently brush off dust that the forced air didn't dislodge.
  10. Brush any remaining dust out from the bottom of the chassis.
  11. Wipe the inside and outside of the cover thoroughly.
  12. Replace the cover and reconnect the peripherals.
  13. Place filter over air intakes.

A clean computer can work much faster than a dirty one!

Cleaning Your Dust Filters

The only maintenance that your computer dust filters need, is proper cleaning. Depending on how dirty the filters are, different methods may be used.

  • Please check the filters on a regular basis to ensure that they stay clean, as dirty filters will hamper airflow.
  • Remove the filter from the case by hand and lay it down on a flat surface.
  • Remove dust and dirt by gently brushing it clean by either using your hand or a soft brush.
  • If the filter becomes excessively dirty, use a bit of soapy water and a soft brush to wash it while it is laid down on a flat surface.
  • Rinse the soap out with cold water under a slow running tap. Do not use hot water as it may cause the filter to delaminate.
  • Again lay the filter flat on some absorbent material like such as towel paper and pat dry from the top.
  • Make sure the filter is completely dry before refitting it to your computer.

If the instructions above are followed carefully, your dust filters will be as good as new.
