Keeping Dust Out of Your Computer (And How to Clean It)

Dust is a computer term that refers to various types of microscopic particles, including soot, dust, dead skin cells and pet hair. This can result in a variety of problems, from a buildup of dirt and grime, creating a layer of filth, to a loss of speed, which can slow down your PC. Also, no one wants to breathe a cloud of dust, but you can prevent it with some basic home maintenance.

Computers. They are loaded with a variety of unsightly dust and dirt particles. You know the kind I’m talking about. Dust bunnies. Hair. Pet dander. Special ointment. The kind of stuff that has you reaching for the can of compressed air and your favorite electronic device cleaner.

Dust can be the enemy of a computer’s internal components. It can accumulate in the space around the hard drive, on the power supply and in even the little fans that keep components cool. It can also collect on the keyboard and mouse, and eventually saturate the motherboard in a way that affects the performance of the computer. If you have a computer that collects dust, there are steps you can take to keep it from damaging the machine..

Keeping the surroundings around your computer immaculate clean is not a practical method for keeping dust out of a computer. Here’s how to prevent over-maintenance and how to properly clean your PC.

The simplest and most efficient method to keep dust out of your computer case is to add intake filters to the intake fans.

The placement of your intake filters is determined by the airflow arrangement established in your computer’s chassis. For additional information, see our page on airflow optimization.

If at all feasible, you should raise your computer case off the floor. This will cut down on the number of times you have to clean your intake filters each year.

Keep your computer clear of dust to ensure long-term performance and dependability.

When dust accumulates on components to the extent that cooling is hindered, performance suffers.

A clean cooling assembly on CPU, GPU, or motherboard components, for example, implies greater cooling, which leads to improved performance and dependability.

How to put in filters to prevent dust from getting into your system

There are two different kinds of air pressure systems. We’ll go through how to handle both.

While having extremes of either kind of configuration isn’t advised, this article assumes you have a slightly biased cooling system, whether it’s toward a positive or negative air pressure cooling arrangement.

Filters are added to a positive pressure cooling system.

Your intake fans are blowing in more air per second than is being blown out, resulting in positive air pressure cooling.

It will only be necessary to install the intake filters in front of the intake fans.

If your case’s fan intake area doesn’t have filters built in, you may buy fan filters tailored to your fan type.

Wherever feasible, I prefer screw mount filters over magnetic filters.

Filters may be added to a negative pressure cooling system.

Negative air pressure cooling is the polar opposite of positive air pressure cooling. When compared to the intake fans, the exhaust air is pushed out quicker.

You’ll need intake filters in front of any intake fan, cooling holes, grills, or other openings if you’re using the negative air pressure cooling technique.

Filter material and magnetic framed filters are available in shops. They come in a variety of sizes, so you should be able to locate one that fits your needs.

Consider low air resistance filters for this kind of filtering technique to guarantee that the air still pulls in via the appropriate regions.

If your filters limit airflow too much, air will enter your case via small cracks and holes elsewhere.

Filtering pitfalls to avoid

Sometimes you’ll see or hear that old stockings or rags may be used as filters, but I strongly advise against it.

Not only is it always preferable to choose the right solution for a job, but when utilizing anything other than appropriate filters, additional finer technical aspects come into play.

  • Cleaning these improvised filters on a regular basis will be more challenging.
  • Can you guarantee that the material has a suitable airflow resistance?
  • Based on the size of the filtering pores, how soon will the filter material get clogged with dust?

How to Keep Your Computer Clean

Before you begin, ensure sure your computer is completely turned off and that all connections are removed.

1. Take off all of the case lids and filters.

Remove any lids and filters that can be readily removed from your case.

2. Disconnect the graphics card as well as any other cards that have a fan (s)

Remove the single screw that secures the card.

You may discover a release clip or a knurled screw that you can remove with your fingertips depending on the case maker.

Avoid touching the edge connections that connect to the expansion slot.

3. Blow away all the dust using compressed air.

Consider using safety glasses and a filter mask before you begin. It’s also a good idea to perform it outdoors.

Blow any dust out of your computer using an air compressor or a container of compressed air.

Make sure you blow out every inch of the house, both inside and out.

Pay special attention to the fan and heatsink on your CPU.

Brush all the blades of all the fans with a dry old toothbrush. Make sure you’re not putting too much pressure on the fan blades.

Give everything a last blowout to ensure that any remaining dust particles are removed.

Give the final blowout to the card slots. Before reinserting the cards that you removed, make sure these spaces are clean.

To maintain your computer steady in its functioning, follow my guide on cleaning your RAM contacts correctly.

4. Clean the lids and filters on the case.

Clean the lids and filters using compressed air. If the filters need further cleaning, immerse them in lukewarm water and give them a gentle wash with hand soap.

After that, give them a thorough rinse with cold water under the faucet.

Just be sure the water isn’t too hot. This may cause any plastic frame on your filter to distort, making it difficult to reassemble.

Allow them to air dry or use a cold hairdryer to speed up the process.

5. Take care of your graphics card.

Blow out the fan and any other vents or heatsink regions that you can see using compressed air.

To ensure that the contacts of the edge connection stay dust-free, give them one last blow.

Complete the following procedures if you inadvertently touched these edge connections (or if you believe they require cleaning):

  1. Using a high-quality pencil eraser, gently wipe the contacts until a clean surface appears.
  2. Clean all of the eraser debris using a lint-free cloth. It may be necessary to switch to clean parts of the cloth a few times until no more eraser deposits are felt.
  3. Make sure the connections are dust and lint-free by blowing them with compressed air.

Important: Make sure you pay special attention to step 2! There mustn’t be any eraser residue on the contacts.

Cleaning RAM follows the same steps as cleaning hard drives. However, be wary about erasing over any tiny surface-mount components.

6. Replace the cards, filters, and case lids as needed.

Reinstall the graphics card, filters, and case lids now that these components are nice and clean.

Congratulations if you’ve made it this far; your computer is now clean!

Associated concerns

How frequently should your computer be cleaned?

Obviously, how effectively your case is filtered and how much dust is there will determine this. However, you should not wait more than a year between visits; preferably, every six to eight months.

Is it possible for dust to harm your computer?

Long-term overheating may cause harm to your computer if critical parts get blocked with dust, causing overheating. Corrosion may occur when dust is mixed with moisture, resulting in damage.


By adding filters to your system, you may lower your maintenance costs and extend the life of your computer’s components.

This implies that having a computer that lasts longer and is more dependable can save you money since you won’t have to constantly buying new computers or components.

Filters are very inexpensive, and you will undoubtedly profit from their installation.

The first thing to remember is to never use a vacuum cleaner to clean your PC. Dust builds up in your computer every time you turn it on, and vacuum cleaners suck the dust right back out of the vents, where it can settle in your computer and cause problems..
